TY - JOUR T1 - Interannual variability of smoke and warm cloud relationships in the Amazon as inferred from MODIS retrievals AN - 20573940; 7920187 AB - Aerosol and cloud data from the MODerate resolution Imaging Spectroradiometer (MODIS) onboard the Earth Observing System (EOS) Aqua are used to investigate interannual variability of smoke and warm cloud relationships during the dry-to-wet transition season (August-October) over the Amazon for two years and its association with meteorological conditions. In one year (2003), smoke aerosols are associated with an increase of cloud fraction and a decrease of cloud effective radius. These effects amplify the cooling at the surface and at the top of the atmosphere (TOA) caused by the aerosol extinction. However, in another year (2002) the cloud fraction decreases with increasing aerosol optical depth. Such a decrease of cloud fraction could offset the effect of increased reflection of solar radiation by the aerosols both at the surface and at TOA. The changes in radiative fluxes between these years would contribute to interannual changes of surface energy fluxes and radiative balance at the top of the atmosphere and influence variability of the wet season onset in the basin. In 2003, the atmosphere was more humid and less stable. These conditions may be relatively favorable for the activation of aerosol particles into cloud condensation nuclei and hence cloud droplets. In 2002, the clouds were less extensive and thinner in a relatively dry atmosphere and presumably dissipated more easily. This study suggests that the aerosol-cloud relation can be influenced by atmospheric structure and convective motions, in addition to changes in aerosols properties. An adequate characterization of aerosol-cloud relationship would require a longer time series of data that includes a variety of climate conditions. The caveat of this analysis is that differences in aerosol absorption and its vertical distribution may have contributed to the observed interannual change of smoke-cloud relationship but could not be determined due to lack of adequate measurements.

Using a numerical model of idealized ice-stream flow coupled to various simple treatments of subglacial bed conditions, we demonstrate that ice-stream flow dynamics significantly modulates the surface-elevation expression of processes taking place at the ice-stream bed. This modulation means that observed surface-elevation changes do not directly translate to basal-elevation changes, e.g. inflation or deflation of subglacial water pockets, of equal magnitude and shape. Thus, subglacial water volume change is not directly proportional to the area integral of surface-elevation changes. Model results show that ambiguities in interpretation of surface elevation changes can be overcome with additional measurements, such as of surface velocity change, and through development of methodology designed to understand transfer of basal change to surface change.

We present an empirical two-band ocean color remote sensing reflectance algorithm (R (sub rs) 670/R (sub rs) 555) for SPM concentrations developed using field measurements obtained in coastal waters influenced by the Mississippi River in 2000, 2002, and 2004. The ratio algorithm was also found to be highly correlated to backscattering coefficient (b (sub bp) (555), r (super 2) =0.96), the backscattering ratio (b (sub bp) (555)/b (sub p) (555), r (super 2) =0.82) and the spectral backscattering slope (gamma , r (super 2) =0.72) in March 2002, a period with large hydrographic variability in the study area. Strong correlations between water column b (sub bp) (555), SPM and nonalgal absorption a (sub nap) (443) suggest the dominant influence of nonalgal particles on b (sub bp) . SeaWiFS derived SPM and gamma distributions indicated event-based variability linked to energetic disturbances such as frontal passages, resuspension, and river discharge that with b (sub bp) /b (sub p) could reveal refractive index and particle size characteristics in the coastal environment.

Results show that the estimated anomalous cooling pattern of the Atlantic during June 2006 relative to June 2005 due to attenuation of surface solar radiation by Saharan dust remarkably resemble observations, accounting for approximately 30-40% of the observed change in sea surface temperature. Historical data analysis show that there is a robust negative correlation between atmospheric dust loading and Atlantic SST consistent with the notion that increased (decreased) Saharan dust is associated with cooling (warming) of the Atlantic during the early hurricane season (July-August-September).

Topics include plant response to elevated CO(2) concentration, interactions with climate change variables and air pollutants, impacts of increased climate variability and frequency of extreme events, the role of weeds and pests, disease and animal health, issues in biodiversity, and vulnerability of soil carbon pools. We critically analyze the links between fundamental knowledge at the plant and plot level and the additional socio-economic variables that determine actual production and trade of food at regional to global scales. We conclude by making recommendations for current and future research needs, with a focus on continued and improved integration of experimental and modeling efforts.

The biological demand for energy is manifest in two requirements, analogous to the voltage and power requirements of an electrical device, which must both be met if life is to be supported. These requirements exhibit discrete (non-zero) minima whose magnitude is set by the biochemistry in question, and they are increased in quantifiable fashion by (i) deviations from biochemically optimal physical and chemical conditions and (ii) energy-expending solutions to problems of resource limitation. The possible rate of energy transduction is constrained by (i) the availability of usable free energy sources in the environment, (ii) limitations on transport of those sources into the cell, (iii) upper limits on the rate at which energy can be stored, transported, and subsequently liberated by biochemical mechanisms (e.g., enzyme saturation effects), and (iv) upper limits imposed by an inability to use "power" and "voltage" at levels that cause material breakdown. A system is habitable when the realized rate of energy transduction equals or exceeds the biological demand for energy. For systems in which water availability is considered a key aspect of habitability (e.g., Mars), the energy balance construct imposes additional, quantitative constraints that may help to prioritize targets in search-for-life missions. Because the biological need for energy is universal, the energy balance construct also helps to constrain habitability in systems (e.g., those envisioned to use solvents other than water) for which little constraint currently exists.

The differences in (super 142) Nd signatures of coeval rocks from the two most extensive crustal relicts more than 3.6 billion years old, in Western Australia and southwest Greenland, reveal early-formed large-scale chemical heterogeneities in Earth's mantle that persisted for at least the first billion years of Earth history. Temporal variations in (super 142) Nd signatures track the subsequent incomplete remixing of very-early-formed mantle chemical domains.

In principle, this should lead to the observation of chemical and isotopic signatures that are characteristic of ocean crust and marine sediments in ocean island basalts. This study investigates the thallium (Tl) isotope systematics of lavas from Iceland and the Azores archipelago, in order to determine if their compositions were affected by admixing of ferromanganese sediments or upper ocean crust altered at low temperature. Such materials are known to display strongly fractionated Tl isotope signatures relative to the ambient upper mantle. Two samples from the island of Terceira in the Azores archipelago have Tl isotope compositions significantly different from normal mantle, and this suggests the presence of Fe-Mn sediments. Combined Pb and Tl isotope modelling indicates that the Tl anomalies are not a feature of the Azores plume but produced by assimilation of modern Fe-Mn sediments during magma ascent through the ocean crust. Excluding these two anomalous lavas from Terceira, the Iceland and Azores samples have identical Tl isotope compositions, with an overall mean of epsilon (super 205) Tl=-1.5+ or -1.4 (2SD, n=30) that is indistinguishable from the previously estimated upper mantle average (epsilon (super 205) Tl=-2.0+ or -0.5). The near-constant Tl isotope compositions of the Iceland and Azores lavas may indicate that the respective mantle plume sources contain virtually no Fe-Mn sediments or altered upper ocean crust. Alternatively, it is possible that the lack of Tl isotope variation reflects quantitative removal of fractionated Tl from the slab during subduction and dehydration. A less straightforward explanation is that past marine environments produced sediments and altered marine basalts with nearly unfractionated Tl isotope compositions. All three scenarios have important implications and future Tl isotope studies will be able to identify the most feasible interpretation.

Two of the ketones produced have been detected in the Murchison Meteorite but, to our knowledge, there has been no search for the alcohols or other oxidized anthracenes in meteorites. These results seem consistent with the possibility that interstellar ice photochemistry could have influenced the inventory of aromatics in meteorites. Since quinones are also fundamental to biochemistry, their formation in space and delivery to planets is relevant to studies relating to the habitability of planets and the evolution of life.

Visible/nearinfrared (VNIR) spectra ( approximately 0.48 to 0.9 mu m) obtained on March 24, 26, and 27 UT, and near-infrared (NIR) spectra ( approximately 0.75 to 2.5 mu m) obtained on March 10, 11, 12, 23, and 24 UT collectively show absorption features centered near 1.0 and 2.0 mu m, which are indicative of olivine and pyroxene. Analyses of these absorption features indicate an abundance ratio of olivine to pyroxene of approximately 75:25 + or - 5, respectively, with no significant variation in the relative abundance of these minerals across its surface on a regional scale. The band center positions indicate that the mean pyroxene chemistry is approximately Wo (sub 14 + or - 5) Fs (sub 43 + or - 5) . There appear to be at least two pyroxene components: primarily a low-Ca orthopyroxene accompanied by a spectrally significant ( approximately 15-20%) high Fe-rich pigeonite phase. The mean pyroxene composition is significantly more Fe-rich than the Fs (sub 14-26) range found in ordinary chondrites. These pyroxene compositions are suggestive of phases crystallized from partial melts. This would indicate that the parent body of (25143) Itokawa reached temperatures sufficient to initiate partial melting ( approximately 1050 to 1250 degrees C), but that it did not attain the degree of melting required for significant melt mobilization and efficient segregation of the basaltic melt component from the unmelted residual olivine portion. Itokawa's spectral band parameters place it near the S(III)/S(IV) boundary, but within the S(III) taxonomic field. In meteoritic nomenclature, Itokawa would be most analogous to an olivine-rich primitive achondrite. Alternatively, if the high Fs value is not related to partial melting, then Itokawa could also represent a rare atypical LL chondrite, or a previously unsampled oxidized Fe-rich chondritic-like assemblage.

The accuracy of such maps is reduced by a number of factors, including variation in backscatter from the different land cover types that are adjacent to the flood, changes in returns from the water surface that are caused by different meteorological conditions, and the presence of emergent vegetation. This paper describes how improved accuracy can be achieved by modifying an existing flood extent delineation algorithm to use airborne laser altimetry [light detection and ranging (lidar)] as well as SAR data. The lidar data provide an additional constraint that water line heights should vary smoothly along the flooded reach. The method was tested on a SAR image of a flood for which contemporaneous aerial photography existed, together with lidar data of the unflooded reach. The water line heights of the SAR flood extent that was conditioned on both SAR and lidar data matched the corresponding heights from the aerial photograph water line significantly more closely than those from the SAR flood extent that was conditioned only on SAR data. For water line heights in areas of low slope and vegetation, the root-mean-square error on the height differences reduced from 221.1 cm for the latter case to 55.5 cm for the former.

Coincident Envisat Synthetic Aperture Radar (SAR) coverage of the region during this period offers a detailed look at the development of the polynyas within several hundred kilometers of the ice front. The high-resolution imagery and derived ice motion fields show bands of polynya ice. In this study, ice thickness from AMSR-E 36 GHz polarization information serves as the basis for examination of the response. The quality of the thickness of newly formed sea ice from AMSR-E is first assessed with thickness estimates derived from ice surface temperatures from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. The effect of large areas of thin ice in lowering the ice concentration estimates from both NT2/ABA approaches is clearly demonstrated. (mod. journ. abst.)

The modular approach adopted for its development includes a phase of candidate selection, followed by template matching, in which the probability associated to each detection is established, and finally, by the analysis of the probability volume, in which the identification of craters on the image is achieved. It is tested on a set of images from four different regions of the surface of the planet Mars, all obtained by the same sensor in the last decade. The recognition rates for craters with radii that are larger than five pixels are very good, both globally and for each of the individual areas. The performance of the algorithm in the face of the variation of some of its parameters is analyzed and discussed in detail. We believe that this is a tool that is suitable for a general application in any area of a planet or satellite captured in an image, whatever the geomorphological setting, the optical sensor, and the conditions of illumination are.

Since the time of the first American expedition to observe the 1780 eclipse during the American Revolutionary War--with the British granting the observation vessel safe passage to Maine's Penobscot Bay--the U.S. government has had a history of supporting scientific expeditions to remote eclipse sites under difficult conditions. A recent expedition to Libya to observe and study the 29 March 2006 eclipse continues that tradition. Copyright 2007 by the American Geophysical Union.

Yet numerical models developed to predict climate change and ice sheet-driven sea level fluctuations have substantial limitations: Poorly represented physical processes in the ice sheet component likely lead to an underestimation of sea level rise forced by a warming climate.

The two products are NASA's gauge-corrected TRMM 3B42 Version 6 (3B42), and the satellite-only NOAA Climate Prediction Center (CPC) morphing technique (CMORPH). The two products were evaluated against ground-based rain gauge-only and gauge-corrected Doppler radar measurements. The analyses were performed at multiple time scales, ranging from annual to diurnal, for the period March 2003 through February 2006. The analyses show that at annual or seasonal time scales, TRMM 3B42 has much lower biases and RMS errors than CMORPH. CMORPH shows season-dependent biases, with overestimation in summer and underestimation in winter. This leads to 50% higher RMS errors in CMORPH's area-averaged daily precipitation than TRMM 3B42. At shorter time scales (5 days or less), CMORPH has slightly less uncertainty, and about 10%-20% higher probability of detection of rain events than TRMM 3B42. In addition, the satellite estimates detect more high-intensity events, causing a remarkable shift in precipitation spectrum. Summertime diurnal cycles in the United States are well captured by both products, although the 8-km CMORPH seems to capture more diurnal features than the 0.25 degree CMORPH or 3B42 products. CMORPH tends to overestimate the amplitude of the diurnal cycles, particularly in the central United States. Possible causes for the discrepancies between these products are discussed.

This is solved in both the approximate continuum limit and the more exact discrete form. A time evolution model is developed for Y DNA or mtDNA that takes into account the reflective boundary modeling minimum microsatellite length and the original difference equation. A comparison is made between the more widely known continuum Gaussian model and a discrete model, which is based on modified Bessel functions of the first kind. A correction is made to the SMM model for the probability that two individuals are related that takes into account a reflecting boundary modeling minimum microsatellite length. This method is generalized to take into account the general n-step model and exact solutions are found. A new model is proposed for the step distribution.

The retrieval algorithm and the accuracy of the parameters retrieved from passive satellite remote sounders must be validated. The Intercontinental Chemical Transport Experiment - North America (INTEXNA) and the European Aqua Thermodynamic Experiment (EAQUATE) provide important validation of satellite observations with ongoing satellite measurement programmes such as Terra, Aura, and Aqua. One of the experimental objectives is to validate chemical species observed from ultraspectral sounders with aircraft in situ measurements, such as the NPOESS Airborne Sounder Testbed-Interferometer (NAST-I). Detailed intercomparisons between aircraft in situ measured and NAST-I retrieved CO profiles were performed to assess the retrieval capability of a passive infrared spectral remote sounder. Validation results illustrate that the CO vertical structure can be obtained by the NAST-I. The thermal radiances are most sensitive to CO emissions from the free troposphere. However, the profile retrieval accuracy depends on the CO uncertainty in the terrestrial boundary layer. It is shown here that the CO distribution in the terrestrial boundary layer over the sea cannot be obtained with reliable accuracy where there is little contrast between the surface air and surface skin temperature.

NEAs fabricated by inlaying vertically aligned carbon nanofibers in SiO sub(2) matrix are applied as "points-and-lid" DEP devices in aqueous solution. The miniaturization of the electrode size provides a highly focused electrical field with the gradient enhanced by orders of magnitude. This generates extremely large positive DEP forces near the electrode surface and traps small bioparticles against strong hydrodynamic forces. This technology promises new capabilities to perform novel cell biology experiments at the nanoscale. We anticipate that the bottom-up approach of such nano-DEP devices allows the integration of millions of nanolectrodes deterministically in lab- on-a-chip devices and will be generally useful for manipulating submicron particles.

These statistics are obtained using validated, high quality Moderate Resolution Imaging Spectroradiometer (MODIS) land surface albedo (MOD43B3) data flagged as snow in the associated Quality Assurance (QA) fields. Near Real-Time Ice and Snow Extent (NISE) data are used as an additional discriminator of snow extent. Statistics are provided for the first seven MODIS bands, ranging from 0.47 to 2.1 mu m, and for three broadbands, 0.3-0.7, 0.3-5.0 and 0.7-5.0 mu m. The statistics demonstrate that each ecosystem classification has a discernible spectral albedo signature when accompanied by snow on the ground. This indicates that winter canopy and the underlying surface radiative properties are impacted by the presence of snow overlying these surfaces. For example, the 0.47 mu m albedo of winter snow-free evergreen needleleaf forests increases from 0.03 to 0.36 in the presence of snow, compared to an increase of 0.04 to 0.76 for croplands. In general, the albedo of snow-covered ecosystems with some winter canopy has lower albedos than ecosystems with little to no winter canopy; for example the 0.47 mu m albedo of snow-covered mixed forests is 0.39 compared to 0.87 for barren/deserts and 0.95 for permanent snow. These statistics can be used within land surface models in a stand-alone mode, to prescribe albedo values in atmospheric General Circulation Models (GCMs), or be incorporated into research and operational projects. They are intended to provide researchers with representative spectral albedo values of IGBP ecosystems in the presence of snow that are derived from validated satellite data.

Most conventional SWE retrieval algorithms depend on the difference between the brightness temperatures (T sub(b)'s) at these frequencies. The effect of atmospheric absorption is generally assumed to be insignificant, and thus often not taken into account in such estimation. In this paper this effect is closely examined with the aid of AMSR-E and radiosonde data sets over two widely separated regions in the continental U.S.A. Results of the analysis show that even under a clear sky the atmospheric absorption could account for as much as ~25-50% to the estimation of SWE. For example, the AMSR-E estimated SWE of 10 cm would become about 13.6 cm when measured at the ground level under the same atmospheric condition; the estimation based on surface emission alone (i.e., no atmosphere) would be about 15.2 cm. There is some regional dependence of this atmospheric absorption effect, but the effect of seasonal variation is negligibly small. Under cloudy conditions, the impact of liquid cloud absorption is significant and it appears necessary to perform either cloud screening or quantify the cloud effects on SWE estimation from 19 to 37 GHz radiometric measurements at ground level or satellite altitudes.

The irregular temporal sampling of ocean color sensors can produce biases in monthly and annual mean chlorophyll estimates. We quantified the biases due to sampling using data assimilation to create a ''truth field'', which we then sub-sampled using the observational patterns of MODIS and SeaWiFS. Monthly and annual mean chlorophyll estimates from these sub-sampled, incomplete daily fields were constructed and compared to monthly and annual means from the complete daily fields of the assimilation model, at a spatial resolution of 1.25 super(o) longitude by 0.67 super(o) latitude. The results showed that global annual mean biases were positive, reaching nearly 8% (MODIS) and >5% (SeaWiFS). For perspective the maximum interannual variability in the SeaWiFS chlorophyll record was about 3%. Annual mean sampling biases were low (<3%) in the mid-latitudes (between -40 super(o) and 40 super(o)). Low interannual variability in the global annual mean sampling biases suggested that global scale trend analyses were valid. High latitude biases were much higher than the global annual means, up to 20% as a basin annual mean, and over 80% in some months. This was the result of the high solar zenith angle exclusion in the processing algorithms. Only data where the solar angle is <75 super(o) are permitted, in contrast to the assimilation which samples regularly over the entire area and month. High solar zenith angles do not facilitate phytoplankton photosynthesis and low chlorophyll concentrations occurring here are missed by the data sets. Ocean color sensors selectively sample in locations and times of favorable phytoplankton growth, producing overestimates of chlorophyll. The biases derived from lack of sampling in the high latitudes varied monthly, leading to artifacts in the apparent seasonal cycle from ocean color sensors. A false secondary peak in chlorophyll occurred in May-August, which resulted from lack of sampling in the Antarctic. Persistent clouds, characteristic in the North Pacific, also produced overestimates, again by selectively sampling only the high growth periods. In contrast, areas characterized by thick aerosols showed chlorophyll underestimates to nearly -30% in basin monthly means. This was the result of selective sampling in lower aerosol thickness periods, which corresponded with lower phytoplankton growth periods. A combination of MODIS and SeaWiFS sampling was most effective at reducing mid-latitude biases due to inter-orbit gaps, sun glint, and sensor tilt changes. But these biases were low using a single sensor, suggesting multiple sensors had little effect in reducing global and regional monthly and annual mean biases. Ocean color data are an invaluable source of information about global biological processes. However, these results suggest that sampling errors need to be considered in applications involving global and regional mean chlorophyll biomasses as well as seasonal variability and regional trend analysis.

Sm and Nd fractionate from each other during silicate differentiation since Nd is less compatible than Sm during magmatic processes, with greater Sm/Nd residues than in partial melts. The two chronometers: (super 146) Sm- (super 142) Nd (t/2 = 103 Ma) and (super 147) Sm- (super 143) Nd (t/2 = 106 X 1000 Ma) are applied to this suite of shergottites and details of the analytical techniques and precisions are listed in the appendix. The results are presented of the enriched shergottites (Shergotty, Zagami, NWA856, Los Angeles), Intermediate (EETA 79001) and depleted (SaU008, DaG476 and SaU094) with published crystallization ages and measured (super 147) Sm/ (super 144) Nd time-integrated ratios, which are plotted against these measured ratios in lavas. A two-stage coupled (super 142) Nd- (super 143) Nd evolution model is derived for a chondritic Martian magma ocean projected to 150 M ago. The linear arrays for the Sm-Nd isotope systematics for these meteorites are consistent with mixing between two separate sources formed approximately 4535 Ma and approximately 4457 Ma ago. An incompatible- trace-element enriched reservoir is suggested to be a late-stage quenched residual melt from the Martian magma ocean in which progressive crystallization occurred for approximately 100 Ma after core formation.The results also imply that a primitive atmosphere was present during this time, acting firstly as an insulating cover and retarding solidification, followed by removal within the first 10 (super 9) yr.

AN - 68433147; 17960273 AB - Microfluidic diaphragm valves and pumps capable of surviving conditions required for unmanned spaceflight applications have been developed. The Pasteur payload of the European ExoMars Rover is expected to experience temperatures ranging between -100 degrees C and +50 degrees C during its transit to Mars and on the Martian surface. As such, the Urey instrument package, which contains at its core a lab-on-a-chip capillary electrophoresis analysis system first demonstrated by Mathies et al., requires valving and pumping systems that are robust under these conditions before and after exposure to liquid samples, which are to be analyzed for chemical signatures of past or present living processes. The microfluidic system developed to meet this requirement uses membranes consisting of Teflon and Teflon AF as a deformable material in the valve seat region between etched Borofloat glass wafers. Pneumatic pressure and vacuum, delivered via off-chip solenoid valves, are used to actuate individual on-chip valves. Valve sealing properties of Teflon diaphragm valves, as well as pumping properties from collections of valves, are characterized. Secondary processing for embossing the membrane against the valve seats after fabrication is performed to optimize single valve sealing characteristics. A variety of different material solutions are found to produce robust devices. The optimal valve system utilizes a membrane of mechanically cut Teflon sandwiched between two thin spun films of Teflon AF-1600 as a composite "laminated" diaphragm. Pump rates up to 1600 nL s(-1) are achieved with pumps of this kind. These high pumping rates are possible because of the very fast response of the membranes to applied pressure, enabling extremely fast pump cycling with relatively small liquid volumes, compared to analogous diaphragm pumps. The developed technologies are robust over extremes of temperature cycling and are applicable in a wide range of chemical environments.

This increase is not related to changing f (sub O2) and the valence of Cr, but rather to the increased availability of elements for coupled substitution with the Cr (super 3+) ion, namely Na and Al. The availability of Al and Na to partition into pyroxene is due to delayed nucleation of plagioclase for the QUE 94201 Martian basalt composition. Direct valence state determination by XANES shows that Cr (super 3+) is the dominant valence state in pyroxene at IW-1, IW, and IW+1. Trivalent Cr is apparently much more compatible in the pyroxene structure than divalent Cr, and thus an increasing D (sub Cr) for both augite/melt and pigeonite/melt with increasing f (sub O2) is a function of the increased activity of Cr (super 3+) in the crystallizing melt.

The ejecta deposits consist of a lower spheroid bed, containing clay and dolomite spheroids, and an upper diamictite bed with boulders and clasts of limestone and dolomite. The matrix of both beds is composed of clay and micritic dolomite. The rare earth element (REE) compositions in the matrix of both units show strong similarities in concentrations and pattern. Furthermore, the Zr/TiO (sub 2) scatter plot shows a linear correlation indicating one source. These results indicate that the basal spheroid bed has the same source and was generated during the same event as the overlying diamictite bed, which lends support to a single-impact scenario for the Albion Formation ejecta deposits. The elevated concentrations of non-meteoritic elements such as Sb, As, U, and Zn in the matrix of the lower spheroid bed are regarded to have been derived from the sedimentary target rocks at the Chicxulub impact site. The positive Eu and Ce anomalies in clay concretion and in the matrix of the lower part of the spheroid bed in Albion Island quarry is probably related to processes involved in the impact, such as high temperature and oxidizing conditions. Analogous trace element anomalies have been reported from the distal Cretaceous-Paleogene (K/T) boundary clay layer at different sites. Thus, the trace element signals, reported herein, are regarded to support a genetic link between the Chicxulub impact, the ejecta deposits along the Mexico-Belize border, and the global K/T boundary layer.

Our study area is 15 650 km (super 2) of the Barrow, AK coastal plain adjacent to the Arctic Ocean; a vast expanse of tundra, lakes, and arctic wetlands of such low relief as to be nearly devoid of terrain features. The accuracy of the ICESat-derived elevation measurements is assessed by comparison with differential global positioning system (DGPS) data acquired along ICESat ground tracks. The ICESat-derived elevations have a mean accuracy, relative to the DGPS elevations, of -0.01 plusmn 0.18 m. ICESat-derived elevations on the Arctic coastal plain provide an excellent source for DEM control. We employ the ICESat-derived ground control points (GCPs) in two distinct InSAR processing steps: 1) selected points are used to perform baseline refinements, which improves the ERS-1 and 2 interfero-grams and 2) the ICESat-derived GCP position data (latitude, longitude, elevation) are then used as control in mosaicking multiple InSAR-derived DEMs. The resulting ICESat-controlled DEM has a mean accuracy of -1.11plusmn 6.3 m relative to an independent standard, which is a commercial airborne InSAR-derived DEM having 0.5 m rms accuracy. This easily meets DTED-2 standards and suggests that DEMs derived using only ICESat altimetry for ground control would meet similar standards in other regions of low relief.

AN - 50255923; 2008-069830 AB - The equatorial Medusae Fossae Formation (MFF) is enigmatic and perhaps among the youngest geologic deposits on Mars. They are thought to be composed of volcanic ash, eolian sediments, or an ice-rich material analogous to polar layered deposits. The Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) instrument aboard the Mars Express Spacecraft has detected nadir echoes offset in time-delay from the surface return in orbits over MFF material. These echoes are interpreted to be from the subsurface interface between the MFF material and the underlying terrain. The delay time between the MFF surface and subsurface echoes is consistent with massive deposits emplaced on generally planar lowlands materials with a real dielectric constant of approximately 2.9+ or -0.4. The real dielectric constant and the estimated dielectric losses are consistent with a substantial component of water ice. However, an anomalously low-density, ice-poor material cannot be ruled out. If ice-rich, the MFF must have a higher percentage of dust and sand than polar layered deposits. The volume of water in an ice-rich MFF deposit would be comparable to that of the south polar layered deposits.

Relying on the recent advances in satellite remote sensing and geographic information system (GIS) techniques, this paper aims to map landslide susceptibility over most of the globe using a GIS-based weighted linear combination method. First, six relevant landslide-controlling factors are derived from geospatial remote sensing data and coded into a GIS system. Next, continuous susceptibility values from low to high are assigned to each of the six factors. Second, a continuous scale of a global landslide susceptibility index is derived using GIS weighted linear combination based on each factor's relative significance to the process of landslide occurrence (e.g., slope is the most important factor, soil types and soil texture are also primary-level parameters, while elevation, land cover types, and drainage density are secondary in importance). Finally, the continuous index map is further classified into six susceptibility categories. Results show the hot spots of landslide-prone regions include the Pacific Rim, the Himalayas and South Asia, Rocky Mountains, Appalachian Mountains, Alps, and parts of the Middle East and Africa. India, China, Nepal, Japan, the USA, and Peru are shown to have landslide-prone areas. This first-cut global landslide susceptibility map forms a starting point to provide a global view of landslide risks and may be used in conjunction with satellite-based precipitation information to potentially detect areas with significant landslide potential due to heavy rainfall.

We present a meta-analysis of new simulations of the full evolution of gas and aerosol species and other existing experiments with variations of the same model. The comparison highlights the importance of several physical processes in determining radiative forcing, especially the effect of climate change on stratosphere-troposphere exchange, heterogeneous sulfate-nitrate- dust chemistry, and changes in methane oxidation and natural emissions. However, the impact of these fairly uncertain physical effects is substantially less than the difference between alternative emission scenarios for all short-lived species. The net global mean annual average direct radiative forcing from the short-lived species is .02 W/m super(2) or less in our projections, as substantial positive ozone forcing is largely offset by negative aerosol direct forcing. Since aerosol reductions also lead to a reduced indirect effect, the global mean surface temperature warms by 60.07 by 2030 and 60.13 by 2050, adding 19% and 17%, respectively, to the warming induced by long-lived greenhouse gases. Regional direct forcings are large, up to 3.8 W/m super(2). The ensemble-mean climate response shows little regional correlation with the spatial pattern of the forcing, however, suggesting that oceanic and atmospheric mixing generally overwhelms the effect of even large localized forcings. Exceptions are the polar regions, where ozone and aerosols may induce substantial seasonal climate changes. JF - Journal of Geophysical Research.

The main goal is to assess the HO sub(x) budget and to quantify the impact of snow emissions on ambient HO sub(x) as well as on CH sub(2)O and H sub(2)O sub(2). This analysis is based on composite diurnal profiles of HO sub(x) precursors recorded during a 3-day period (July 7-9), which were generally compatible with values reported in earlier studies. The model simulations can reproduce the observed diurnal variation in HO sub(2)+RO sub(2) when they are constrained by observations of H sub(2)O sub(2) and CH sub(2)O. By contrast, model predictions of OH were about factor of 2 higher than the observed values. Modeling analysis of H sub(2)O sub(2) suggests that its distinct diurnal variation is likely controlled by snow emissions and loss by deposition and/or scavenging. Similarly, deposition and/or scavenging sinks are needed to reproduce the observed diel profile in CH sub(2)O. This study suggests that for the Summit 2003 period snow emissions contribute ~25% of the total CH sub(2)O production, while photochemical oxidation of hydrocarbon appears to be the dominant source. A budget assessment of HO sub(x) radicals shows that primary production from O( super(1)D)+H sub(2)O and photolysis of snow emitted precursors (i.e., H sub(2)O sub(2) and CH sub(2)O) are the largest primary HO sub(x) sources at Summit, contributing 41% and 40%, respectively. The snow contribution to the HO sub(x) budget is mostly in the form of emissions of H sub(2)O sub(2). The dominant HO sub(x) sink involves the HO sub(2)+HO sub(2) reaction forming H sub(2)O sub(2), followed by its deposition to snow. These results differ from those previously reported for the South Pole (SP), in that primary production of HO sub(x) was shown to be largely driven by both the photolysis of CH sub(2)O and H sub(2)O sub(2) emissions (46%) with smaller contributions coming from the oxidation of CH sub(4) and the O( super(1)D)+H sub(2)O reaction (i.e., 27% each). In sharp contrast to the findings at Summit in 2003, due to the much higher levels of NO sub(x), the SP HO sub(x) sinks are dominated by HO sub(x)-NO sub(x) reactions, leading to the formation and deposition of HNO sub(3) and HO sub(2)NO sub(2). Thus, a comparison between SP and Summit studies suggests that snow emissions appear to play a prominent role in controlling primary HO sub(x) production in both environments. However, as regards to maintaining highly elevated levels of OH, the two environments differ substantially. At Summit the elevated rate for primary production of HO sub(x) is most important; whereas, at SP it is the rapid recycling of the more prevalent HO sub(2) radical, through reaction with NO, back to OH that is primarily responsible.

Accurately simulating urbanization-induced temperature hazard is critical for realistically representing urban regions in the land surface-atmosphere climate system. However, inclusion of urban landscapes in regional or global climate models has been overlooked due to the coarse spatial resolution of these models as well as the lack of observations for urban physical properties. Recently, National Aeronautics and Space Administration (NASA) Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) observations illustrate important urban physical properties, including skin temperature, surface albedo, surface emissivity, and leaf area index, It is possible to identify the unique urban features globally and thus simulate global urban processes. An urban scheme is designed to represent the urban-modified physical parameters (albedo, emissivity, land cover, roughness length, thermal and hydraulic properties) and to include new, unique physical processes that exist in urban regions. The urban scheme is coupled with National Center for Atmospheric Research (NCAR) Community Land Model Version 2 (CLM2) and single column coupled NCAR Community Atmosphere Model CAM2/CLM2 to assess the mechanisms responsible for UHI. There are two-steps in our model development. First, satellite observations of albedo, emissivity, LAI, and in situ observed thermal properties are updated in CLM2 to represent the first-order urban effects. Second, new terms representing the urban anthropogenic heat flux, storage heat flux, and roughness length are calculated in the model. Model simulations suggest that human activity-induced surface temperature hazard results in overlying atmosphere instability and convective rainfall, which may enhance the possibility of urban flood hazard.

Two sets of QPFs are made, one using the initial water vapor field from the NCEP 40-km Eta initial analysis, and another in which the initial Eta water vapor field is modified by incorporating the PWV data from the SCIGN receivers. Lateral boundary data for the QPFs, as well as the hydrostatic component of the GPS zenith delay data, are estimated from the Eta analysis. Case studies of a winter storm on 2 February during the 1997/98 El Nino, and storms leading up to the La Conchita, California, landslide on 10 January 2005, show notably improved QPFs for the first 3-6 h with the addition of GPS PWV data. For a total of 47 winter storm forecasts between February 1998 and January 2005 the average absolute QPF improvement is small; however, QPF improvements exceed 5 mm in several underpredicted rainfall events, with GPS data also improving most cases with overpredicted rainfall. The GPS improvements are most significant (above or near the 2s level) when the low-level winds off the coast of Southern California are from the southern (SW to SE) quadrant. To extend the useful forecast skill enhancement beyond six hours, however, additional sources of water vapor data over broader areas of the adjacent Pacific Ocean are needed.

With the availability of satellite rainfall analyses at fine time and space resolution, it has also become possible to mitigate such hazards on a near-global basis. In this article, a framework to detect floods and landslides related to heavy rain events in near-real-time is proposed. Key components of the framework are: a fine resolution precipitation acquisition system; a comprehensive land surface database; a hydrological modeling component; and landslide and debris flow model components. A key precipitation input dataset for the integrated applications is the NASA TRMM-based multi-satellite precipitation estimates. This dataset provides near real-time precipitation at a spatial-temporal resolution of 3 h and 0.25 degree x 0.25 degree . In combination with global land surface datasets it is now possible to expand regional hazard modeling components into a global identification/monitoring system for flood/landslide disaster preparedness and mitigation.

Atacama and Mars soils have similar sulfate concentrations; possess phyllosilicates (e.g., smectite) and minor carbonate. Nitrate has not been detected on Mars, but its presence has been proposed. The similar compositions of Atacama and Mars soils have prompted the visible-infrared (0.35-25 [mu]m) investigation of Atacama soils as Mars analogs. Results from this work determined the best infrared features for detecting sulfate, nitrate, carbonate, and phyllosilicate on Mars. The fundamental region (>6.5 [mu]m) was not suited for salt and phyllosilicate detection because of overlapping spectra from primary silicates (e.g., feldspar), water and carbon dioxide. The visible near-infrared (0.35-2.5 [mu]m) region was suited for detecting carbonate, nitrate, gypsum water of hydration, and phyllosilicate hydroxyls without interference from primary silicates. However, gypsum water of hydration features can obscure phyllosilicate hydroxyl, carbonate and nitrate, features if gypsum levels are high. Overtone/combination absorption features in the midinfrared were determined to be the best indicators of sulfate (4.48-4.70 [mu]m), nitrate (4.12 [mu]m), and carbonate (3.98 [mu]m) because interferences from overlapping primary silicate and water features are not present in this region. Interferences from CO sub(2) and thermal emission effects in the overtone/combination region are possible but may be minimized by corrective techniques. Infrared analysis of Atacama Desert soils can provide insight into the spectral search of sulfate, nitrate, carbonate, and phyllosilicate containing soils on Mars.

The AIE comprises of i) Fountoukis and Nenes aerosol activation module for obtaining cloud condensation nuclei; ii) Seifert and Beheng algorithms for precipitation microphysics but with modified accretion constant for the coarse vertical-resolution typical of a global general circulation model (GCM); and iii) Khvorostyanov and Curry parameterization for computing the effective radius (r sub(e)) of cloud drops. The upgraded package, named McRAS-AC, was evaluated using the 3-year ARM-SGP Single Column Model (SCM) data. Invoking only the most dominant sulfate aerosols over the region, McRAS-AC simulated realistic annual mean and annual cycles of cloud water, cloud optical thicknesses, cloud drop number concentration, and r sub(e). The follow-on SCM-sensitivity simulations showed that accretion of cloud water is sensitive to i) the terminal velocity of hydrometeors produced by autoconversion and ii) cloud height increases due to in-cloud condensation heating. The impact of aerosol mass concentration on the resultant column cloud water, and bulk optical properties of clouds were assessed by using 1/8 to 8 times the average monthly aerosol mass concentration estimates of GOCART aerosol climatology. A log-linear relation between cloud-radiative forcing and aerosol-mass concentration emerged in the simulated data.

C57BL/6 adult (10- to 12-week) male mice were exposed by whole-body inhalation to control air or 0.3, 1, or 5 mg/m super(3) respirable aggregates of MWCNTs for 7 or 14 days (6 h/day). Histopathology of lungs from exposed animals showed alveolar macrophages containing black particles; however, there was no inflammation or tissue damage observed. Bronchial alveolar lavage fluid also demonstrated particle-laden macrophages; however, white blood cell counts were not increased compared to controls. MWCNT exposures to 0.3 mg/m super(3) and higher particle concentrations caused nonmonotonic systemic immunosuppression after 14 days but not after 7 days. Immunosuppression was characterized by reduced T-cell-dependent antibody response to sheep erythrocytes as well as T-cell proliferative ability in presence of mitogen, Concanavalin A. Assessment of nonspecific natural killer (NK) cell activity showed that animals exposed to 1 mg/m super(3) had decreased NK cell function. Gene expression analysis of selected cytokines and an indicator of oxidative stress were assessed in lung tissue and spleen. No changes in gene expression were observed in lung; however, interleukin-10 (IL-10) and NAD(P)H oxidoreductase 1 mRNA levels were increased in spleen.

The ASD is intended to serve as a cost effective front-end monitor for anthrax surveillance systems. The principle of operation is based on measuring airborne endospore concentrations, where a sharp concentration increase signals an anthrax attack. The ASD features an air sampler, a thermal lysis unit, a syringe pump, a time-gated spectrometer, and endospore detection chemistry comprised of dipicolinic acid (DPA)-triggered terbium ion (Tb3+) luminescence. Anthrax attacks were simulated using aerosolized Bacillus atrophaeus spores in fumed silica, and corresponding Tb-DPA intensities were monitored as a function of time and correlated to the number of airborne endospores collected. A concentration dependence of 102-106 spores/mg of fumed silica yielded a dynamic range of 4 orders of magnitude and a limit of detection of 16 spores/L when 250 L of air were sampled. Simulated attacks were detected in less than 15 min.

Historical Case Studies From the US, Italy, and Sri Lanka AN - 954461384; 11692150 AB - Malaria is currently prevalent in many countries and has been for centuries. Primary controllers of the distribution and incidence of malaria in the past have been economic, social, military, political etc. with a modest contribution from local climate variations. Studies of potential impacts of climate change on the epidemiology of diseases such as malaria have focused on the impact of changing environmental conditions on vector physiology but little attention has been paid to factors that explain historical variations in spatial and temporal distributions of the disease. This talk reports results of three historical case studies from the US, Italy and Sri Lanka that bring together a breadth of information from varied sources in order to illustrate the value of including such information in studies of disease-climate connections.

In this paper, the authors propose an algorithm that estimates thin ice thickness and detects fast ice using Defense Meteorological Satellite Program (DMSP) Special Sensor Microwave Imager (SSM/I) data in the Antarctic Ocean. Detection and estimation of sea ice thicknesses of <0.2 m are based on the SSM/I 85- and 37-GHz polarization ratios (PR85 and PR37) through a comparison with sea ice thicknesses estimated from the Advanced Very High Resolution Radiometer (AVHRR) data. The exclusion of data affected by atmospheric water vapor is discussed. Because thin ice and fast ice (specifically ice shelves, glacier tongues, icebergs, and landfast ice) have similar PR signatures, a scheme was developed to separate these two surface types before the application of the thin ice algorithm to coastal polynyas. The probability that the algorithm correctly distinguishes thin ice from thick ice and from fast ice is approximately 95%, relative to the ice thicknesses estimated from AVHRR. Although the standard deviation of the difference between the thin ice thicknesses estimated from the SSM/I algorithm and AVHRR is approximately 0.05 m and thus not small, the estimated ice thicknesses from the microwave algorithm appear to have small biases and the accuracies are independent of region and season. A distribution map of thin ice occurrences derived from the SSM/I algorithm represents the Ross Sea coastal polynya being by far the largest among the Antarctic coastal polynyas; the Weddell Sea coastal polynyas are much smaller. Along the coast of East Antarctica, coastal polynyas frequently form on the western side of peninsulas and glacier tongues, downstream of the Antarctic Coastal Current.

Rather than driving impact models with conditions based upon summary statistics from an ensemble of global climate models (GCMs) or relying on a prescribed range of inputs, end-to-end assessment is conducted for a wide variety of GCMs and emissions scenarios. The resulting distribution of impacts may be used to elucidate internal dynamics of the system and to attach model and societal-based probabilities to individual outcomes.To demonstrate the method, preliminary results from a World Bank project on the effect of climate change on Bangladesh's agricultural sector are presented. Working with a wide range of collaborators in Bangladesh, 48 climate change scenarios (16 GCMs and 3 emissions scenarios) were generated from 2020-2100 for each of 16 regions in Bangladesh. These scenarios were then used to drive the Decision Support System for Agrotechnology Transfer (DSSAT) biophysical model for major cereal crops. Output generated from a smaller subset of hydrologic and coastal model scenarios is then used to adjust the yield production to account for projected river floods in the Ganges/Brahmaputra/Meghna basin and coastal inundation from the Bay of Bengal, respectively. The result is a probabilistic distribution of agricultural impacts for Bangladesh that retains model and societal uncertainties throughout the assessment process.

Four main geologic features are present in the mapping area: 1) the main shield, 2) the rift aprons, 3) plains lava flows, and 4) a fan-shaped debris apron. Along with the current version of the geologic map, we will present a focused analysis of the geomorphology and formation of chasmata associated with the rift zones. The rift aprons extend from the lower northeast and southwest flanks of the main shield. At the apex of the rift aprons are a dense concentration of intertwined chasms and chains of pit craters that together make up the rift zones. Morphologically, the chasms have theater-shaped heads and narrow downstream. The orientations of the chasms trend with the slope of the main shield. No levees or flow margins are apparent giving the individual chasms a morphologic appearance similar to lunar sinuous rilles. The chasms are typically 1-3 km wide, with some coalesced areas up to 8-km-wide, and are 100's of meters deep, based on MOLA gridded data (128 pixels/degree). High-resolution images from MOC (2.9-6.1 m/pixel) and High Resolution Imaging Science Experiment (HiRISE) (0.25 m/pixel) reveal layers of bedrock in the upper quarter to upper half of the chasm walls, with the lower sections of the walls covered by debris and dust. HiRISE image PSP_001642_1895 shows at least ten layers of bedrock cropping out in a staircase-like fashion in the upper quarter of a chasm wall on the southwest flank of Ascraeus Mons. We interpret the bedrock layers observed in this HiRISE image to be lava flows that were emplaced during construction of the main shield, which are now exposed as a result of the chasm formation. Formation of the chasmata is thought to be by various processes including volcanic, tectonic, fluvial, and glacial or a combination thereof. We agree with a volcanic origin for the chasmata, formed by high volume, long duration eruptions and the release of volatiles along a NE-SW trending rift zone. Chasms were modified later by other surface processes. Intruding magma surfaced along the lower flank of Ascraeus Mons feeding the flow field that comprises the rift apron. Understanding the origin of the chasmata will provide better insight into the eruption dynamics required to form the rift aprons.

It is also an important prerequisite for studies of comparative planetology, e.g., the comparison between terrestrial and planetary surface features. Numerous small and low shield volcanoes on Mars and associated vents and lava flows have previously (e.g., Plescia, 1981) been compared to terrestrial plains volcanism, as defined by Greeley (1982) to be intermediate between flood basalts and the Hawaixian shields. However, the Martian low shields got relatively little attention so far, and despite some work on their topography (e.g., Sakimoto et al., 2003), not many thorough analyses have been carried out so far. This study investigates the topography and morphology of the low shields and associated landforms using MOLA, THEMIS, and MOC data. They display many similarities with terrestrial basaltic volcanic fields, and so far we did not identify any features that are unknown from Earth. They include relatively small and low shields, lava flows, which are often associated with lava channels and tunnels, and volcanic rift zones. Our results reconfirm the Viking-based conclusion that plains volcanism in the eastern Snake River plains is perhaps the best terrestrial morphological analogue for these Martian surface features. Icelandic shields, distinct structures in Hawaixi, and other basaltic landforms also show some similarities to Martian plains volcanism. Landforms previously not known from the low shields are sinuous rilles, interpreted as evidence for high eruption rates, spatter cones, and inflation features. Extremely shallow flank slopes of less than 0.5 degrees suggest the eruption of lavas with very low viscosity, which might be the result of high eruption temperatures, high effusion rates, a low Si- and a high Mg-content along with a possible high Fe-content, or a combination of these factors. The distribution of low shields in Tharsis does not show any obvious association with large-scale tectonic features. They might represent recent volcanism, which is not related to mantle plumes, but to a zone of partial melting in an anomalously warm mantle underneath a thickened crust (see the new model recent Martian volcanism of Schumacher and Breuer, 2006, 2007).

The products produced by these processes result in substantial changes in the optical and physical properties of planetary surfaces. Space weathering discussions have generally centered on soils, but exposed rocks will also incur the effects of weathering. Rocks have much longer surface lifetimes than an individual soil grain and thus record a longer history of exposure. By studying the weathering products which have built up on a rock surface, we can gain a deeper perspective on the weathering process and better assess the relative importance of various weathering components. Using FIB (focused ion beam) techniques, we have been able to extract several micro-cross-sections through the weathered patina on lunar rock 76015 in which the delicate stratigraphy of the patina coating is beautifully preserved recording roughly 22 million years of exposure to the space environment. Weathering processes, particularly micrometeorite bombardment and sputtering from solar wind particles, can both deposit and erode material from the surface. The patina varies in thickness across our samples from none in some places, to several microns thick in others. It is composed of many discrete melt- and vapor-deposited units of varying sizes and thicknesses, some stretching across much of the section, others only a few hundred nanometers in extent. By volume, there is considerably more melt deposited than vapor or sputtered material. The boundaries between units are generally sharp, suggesting fast cooling rates. The units are compositionally quite heterogeneous, similar to the range seen in lunar agglutinate glasses. Some of the units are rich in nanophase metallic iron, others have little or none. In general, smaller glass units tend to be more enriched in nanophase iron than larger units. Several small grains have been entrained among the glass units. The preservation of solar flare particle tracks in the accreted grains and substrate implies cold accretion. The complexity and variability of the stratigraphy within the sections we have studied is providing unique insights into the complex and stochastic nature of space weathering.

Features in various places on Earth (Tamlamakan Desert, China; Namib Desert, Namibia; Thar Desert, India; Sahara Desert, Mauritania and Niger; Rub al Khali, Saudi Arabia) and Mars (Chasma Boreale, Noachis Terra, Wirtz Crater) provide insights into the characteristics and origin of wind-related landforms on Titan seen by the Cassini RADAR. Longitudinal duneforms are the most common depositional features seen in the equatorial regions of Titan and indicate supplies of sand-sized particles blown generally by bidirectional winds. The terrestrial analog sites chosen exhibit diverse wind features that are generally well understood and have morphologies comparable to those on Titan. Key features of terrestrial and Martian dune morphology may that appear in the comparatively lower resolution RADAR images of Titan in the equatorial regions include extension of barchan horns (e.g. T3 swath at approximately 30 lat, 15 lon; T28 swath at approximately 0 lat, 28 lon), merging barchan convoys (T3 swath at approximately 30 lat, 15 lon), climbing dunes (T3 swath at approximately 10 lat, 120 lon), sand streaks indicating seasonal wind directions (T3 swath at approximately 10 lat, 115 lon; T25 swath at approximately 0 lat, 40 lon), and transitions of linear dunes to transverse dunes (T8 swath at approximately 10 lat, 230 lon). Although these features appear on Titan at resolutions that often preclude definitive characterization, their presence strengthens the case for the dune fields having familiar characteristics and behaviors and being active currently or in the past. Analysis of these features and application to Titan adds to the understanding of the evolution of the Titanian dune forms and their transition to other terrains as well as implications for global climate models and wind patterns.

The recent detection of methane occurring in the Martian atmosphere and the possibility that its origin could be attributed to biological activity, have highlighted the importance of understanding the mechanisms that distinguish biogenic from abiogenic sources. A number of recent studies have demonstrated that methane produced by purely abiological processes (>120 degrees C) can be difficult to distinguish from methane produced biologically at low temperature (<120 degrees C). The delta 13C of the methane has traditionally been used as the critical factor in distinguishing between different methane sources, where it was thought that biological processes were responsible for methane with very light carbon isotope ratios ( approximately -60ppm) while methane with delta 13C values closer to 0ppm were formed abiogenically. It has been now shown that biological and non-biological methane can have variable delta 13C values making delta 13C alone an unreliable identifier for non-biological methane provenance. Clearly, the difficulty in distinguishing biogenic from abiogenic methane in terrestrial continental aqueous systems makes it all the more difficult to ascertain methane origin on the surface of Mars and therefore draw conclusions on the existence of a Martian biosphere. In this work we outline a novel technique for determining methane biogenicity. We report the delta 13C of CO2 and CH4 of gases collected from two terrestrial hot springs: Great Boiling Springs, NV (GBS) and Surprise Valley Hot Springs, CA (SVHS). The delta 13C values for CO2 range from -12.0 to -8.5ppm for GBS, and from -24.8 to -12.8ppm for SVHS. delta 13C values for CH4 range from -48.3 to -24.9ppm for GBS, and from -51.2 to -50.0ppm for SVHS. Our data indicate that methane is in isotopic equilibrium with CO2 at depth and therefore provides a means to calculate formation temperature. All samples indicate temperatures above 155 degrees C using calculated carbon isotope equilibrium fractionation factors. This minimum formation temperature excludes the possibility that CH4 formed directly from the action of microorganisms, and is consistent with the lack of detection of methanogens from most of these springs using culture-independent molecular techniques.

Sand dunes and other aeolian features are unique in the study of climate change in that they are geological features formed by atmospheric forces. In particular, cold-climate sand dunes are surface features that become more active under windy, nonicy conditions, but less active under nonwindy and/or icy conditions. Thus they are extremely sensitive to changes in temperature, humidity, and atmospheric dynamics that drive climate change. The presence of a well-defined shift in southern hemisphere dune morphology may shed new light on recent climate change on Mars. Poleward of roughly 60 degrees S, dunes take on a rounded and eroded appearance consistent with inactivity, whereas dunes equatorward of this latitude appear largely indistinguishable from active dunes. All dune fields poleward of 55 degrees S that are visible in Mars Odyssey THEMIS visible images and Mars Global Surveyor Mars Orbiter Camera (MGS MOC) images have been identified and categorized according to their level of degradation. Preliminary results suggest that the morphological shift occurs at approximately 60 degrees S at all longitudes, generally corresponding well with the boundary of near-surface ground ice according to ground ice models, terrain morphological studies, and data from the Neutron Spectrometer on Mars Odyssey. In one meridional corridor (40 degrees E-130 degrees E, south and east of Hellas Planitia), Neutron Spectrometer data extend as far north as 50 degrees S. This bulge is not reflected in dune morphology, suggesting that any link between ground ice and dune morphology is complex.

These tiny deposits formed by vapor condensation during cooling of the gases that drove the fire fountain eruptions responsible for the formation of the beads. Volcanic glass beads are present in most lunar soil samples in the returned lunar collection. The mare-composition beads formed as a result of fire-fountaining approximately 3.4-3.7 Ga ago, within the age range of large-scale mare volcanism. Some samples from the Apollo 15 and Apollo 17 landing sites are enriched in volcanic spherules. Three major types of volcanic glass bead have been identified: Apollo 15 green glass, Apollo 17 orange glass, and Apollo 17 "black" glass. The Apollo 15 green glass has a primitive composition with low Ti. The high-Ti compositions of the orange and black glasses are essentially identical to each other but the black glasses are opaque because of quench crystallization. A poorly understood feature common to the Apollo 15 and 17 volcanic glasses is the presence of small deposits of unusual materials on their exterior surfaces. For example, early studies indicated that the Apollo 17 orange glasses had surface enrichments of In, Cd, Zn, Ga, Ge, Au, and Na, and possible Pb- and Zn- sulfides, but it was not possible to characterize the surface features in detail. Technological advances now permit us to examine such features in detail. Preliminary FE-TEM/X-ray studies of ultramicrotome sections of Apollo 15 green glass indicate that the surface deposits are heterogeneous and layered, with an inner layer consisting of Fe with minor S and an outer layer of Fe and no S, and scattered Zn enrichments. Layering in surface deposits has not been identified previously; it will be key to defining the history of lunar fire fountaining.

In the well-exposed and well-preserved terrains, such as the young flood lavas in Elysium Planitia, the morphologic and topographic information provided at approximately 30 cm/pixel in HiRISE stereo image pairs is yielding fundamentally new insight into volcanic processes. However, in areas where the volcanic surfaces are either mantled or degraded, we find that the 6 m/pixel MRO Context (CTX) images are optimal for volcanological studies. The mantling deposit is apparently tens of meters thick on the major shield volcanoes. Also, while the HiRISE color data have proven invaluable in many studies, most Martian volcanic terrains are sufficiently dust-covered to limit the utility of these data. One counter example is that, in cross-section, the thick mantling deposit on the flanks of Olympus Mons is found to be different in color than dust-covered surfaces. This suggests that this approximately 60 m thick deposit may have a different composition (and genesis) than the dust that settles from the atmosphere. One possible explanation is that this is a young airfall deposit of volcanic ash. Kilometer-scale vent structures show a great deal of diversity, including examples that appear to have been primarily effusive, primarily explosive, or exhibit a combination of eruptive styles. Lava flows also show a diversity that may exceed the range of well-preserved eruptive styles seen in mafic eruptions on the Earth. In addition to many large aa-like lava flows, we have imaged platy-ridged (i.e., rubbly pahoehoe) flood lavas, and inflated pahoehoe sheet flows similar to terrestrial examples (except perhaps in erupted volume). However, there are also indications of very large turbulent floods of lava that may not have any well-preserved terrestrial counterparts. The HiRISE observations may provide insight into very large flood lava flows on Venus, the ancient Earth, the Moon, and Io. Perhaps most important for the current Mars exploration strategy is the clear evidence for recent hydrovolcanic activity in the equatorial lowlands.

AN - 746073349; 11696472 AB - Large-scale distributions of ozone (O sub(3)) and aerosols were measured with a differential absorption lidar (DIAL) on the NASA DC-8 aircraft during the Megacity Initiative: Local Global and Research Observations (MILAGRO) and Intercontinental Chemical Transport Experiment - Phase B (INTEX-B) field experiments conducted from 24 February - 22 March 2006 and 17 April - 15 May 2006, respectively. Remote O sub(3) and multi-wavelength aerosol backscatter and aerosol depolarization profiles were simultaneously measured below and above the DC-8 along its ground track. During the INTEX-B Pacific phase, long-range transport of aged and relatively fresh Asian pollution was often observed in the free troposphere in eastern Pacific. Average latitudinal and longitudinal variations of O sub(3) and aerosols have been derived from the remote and in situ O sub(3) data for INTEX-B. This paper presents comparisons between the measured averaged tropospheric O sub(3) cross sections and analyses from several chemical transport models demonstrating that they have general agreement in atmospheric structure and pollution layer features. However, several general trends were found between the observations and the models. Compared to DIAL measurements, two models underestimate O sub(3) by 2-10 ppbv in the lower troposphere (0-6 km) and all the models overestimate O sub(3) in the upper troposphere (10-12 km) by 8-20 ppbv. The O sub(3) difference between models and DIAL measurements do not show significant trends over the range of latitudes (22-61 N) observed. The contribution of stratosphere-troposphere exchange to the latitudinal variation of O sub(3) over the Pacific has also been examined, and these results will also be presented.

AN - 744674377; 11690838 AB - Clay-supported TiO2 photocatalysts can potentially improve the performance of air treatment technologies due to enhanced adsorption and reactivity of volatile organic compounds (VOCs). In this study, a bench-top photocatalytic flow reactor was used to evaluate hectorite-TiO2 and kaolinite-TiO2, two novel composite materials synthesized in our laboratory. Toluene, a model hydrophobic VOC and a common indoor air pollutant, was introduced in the air stream at realistic concentrations and reacted under UVA (l max = 365 nm) or UVC (l max = 254 nm) irradiation. The UVC lamp presented secondary emission at 185 nm, leading to the formation of ozone and other short-lived reactive species. Performance of clay-TiO2 composites was compared with that of pure TiO2 (Degussa P25) and with UV irradiation in the absence of photocatalyst under identical conditions. Films of clay-TiO2 composites and of P25 were prepared by a dip- coating method on the surface of Raschig rings placed inside the flow reactor. An upstream toluene concentration of 150 ppbv was generated by diluting a constant vapor flow with dry air, or with humid air at 10, 33, and 66 % relative humidity (RH). Toluene concentrations downstream were determined by collecting Tenax-TA ® sorbent tubes and subsequent thermal desorption/gas chromatography/mass spectrometry (TD/GC/MS) analysis. The fraction of toluene removed, %R, and the reaction rate, Tr, were calculated for each experimental condition from the concentration changes registered with and without UV irradiation. Use of UVC light (UV/TiO2/O3) led to overall higher reactivity, which can be partially attributed to contribution of gas phase reactions by O3 and other short-lived species. When the reaction rate was normalized by the light irradiance, Tr/Iλ , the UV/TiO2 reaction under UVA irradiation was more efficient for samples with a higher content of TiO2 (P25 and Hecto-TiO2), but not for Kao-TiO2. Considering the effect of relative humidity, in all cases reaction rates peaked at 10% RH, with values 10-50% higher than those measured under dry air. However, a net inhibition was observed as RH increased, indicating that water molecules competed effectively with toluene for reactive surface sites and limited the overall photocatalytic conversion. As compared with P25, inhibition by co-adsorbed water was less significant for Kao-TiO2 samples, but was more dramatic in the case of Hecto-TiO2 due to the high water uptake capacity of the hectorite clay.

Starting with a single strong layer with power-law creep rheology over a weaker substrate, she systematically explored the wavelengths and growth rates of instabilities leading to boudinage and folding, extending the semi-analytic, infinitesimal perturbative methods of Fletcher [1974] to multiple layers representing differing crust and mantle rheologies and continuous strength envelopes. Such methods placed constraints on the thermal structure and tectonic history of Earth, Venus, and Mars. As finite element methods became available on workstations, she and her colleagues considered the behavior of layered rheologies and growth of faults in finite extension. Following the discovery of 150-250-km-wavelength cross-grain gravity lineations in the Pacific Plate [Haxby, 1986], some attempted to explain these as extensional instabilities under plate driving forces [Winterer and Sandwell, 1987], while others proposed small-scale convection as the underlying mechanism [e.g., Buck and Parmentier, 1986]. Plate motions, mantle rheology, stress, and thermal state in the past are poorly constrained. Whether diffuse extension or small-scale convection or some other mechanism is the prime source of the short wavelength undulations remains an open question [Wessel and Bercovici, 1996; Sandwell and Fialko, 2004; Forsyth et al., 2006]. In any case, finite-amplitude deformation of a cooling, extending lithosphere does not lend itself to simple analytic models, and is complicated by the coupling of thermal and density anomalies to finite strain with Coulomb strength envelopes under gravitational loads. Such a regime may exist not only at mid-ocean ridges but in transient spreading centers of the terrestrial planets and icy moons. This paper will show that a multi-layer approximation to young oceanic lithosphere tends to have the highest growth rates of instabilities at wavelengths 4x lithospheric thickness, casting doubt on the extensional boudinage mechanism for wavelengths in excess of 150 km. Model strength envelopes that achieve the observed Pacific Plate wavelength have low growth rates. We also review the results of finite-element models for a case applicable to the oceanic problem.

Archean organic matter not only tends to be poorly preserved, but it also may include remnants of both biogenic and non-biogenic processes and may co-exist with younger post-depositional contaminants. The new technology of NanoSIMS, however, is providing sub-micron scale elemental and isotopic analyses that can address these complexities. For example, a recent study of Neoproterozoic organic microfossils (super 1) has demonstrated that metabolically important elements (e.g., C, N, and S) can be correlated with cellular structures identified by optical microscopy. That study also suggested that N/C ratios reflect precursor compounds and may be important biosignatures. These results illustrate nano-scale structure and elemental composition of clearly biogenic remains and thus can be used as guidelines for interpreting less well preserved organic fragments from older or even extraterrestrial materials. Moreover, since NanoSIMS allows materials to be analyzed in thin section, spatial relationships between organic matter, the mineral matrix, and any veins or cracks can be determined, allowing discrimination between indigenous material and possible post-depositional contamination by younger microbes, migration of soluble organic molecules, or hydrothermal alteration. New NanoSIMS investigations of early Archean cherts from the Pilbara of Western Australia demonstrate that organic carbon within the matrix of these cherts has morphological and elemental characteristics different from those of organic carbon that occurs in hydrothermal veins. In addition, the organic structures in the matrix have a spatial relationship to Si and O that seemingly reflects silica nucleation on organic surfaces, (super 1) arguing that those structures are the same age as the mineral matrix and thus are not post-depositional contaminants. Finally, some of the organic structures in the matrix have NanoSIMS element maps reminiscent of those from the undisputedly biogenic, Neoproterozoic microfossils. (super 1) While that similarity might suggest a biological origin for the early Archean structures, additional analyses including isotopic determinations are planned to further evaluate this possibility.

Approximately 30% of the total volatile material is involved in this process and one of the consequences of this redistribution of the mass is a change in the gravity field of the planet that causes observable effects on the motion of spacecraft in Mars orbit. The basic process is one in which atmospheric CO2 is deposited on the winter pole with a corresponding reduction in atmospheric pressure followed by a sublimation back into the atmosphere and an increase in pressure. This process causes a semiannual variation in the mass of the atmosphere but because the orbit of Mars is eccentric the southern hemisphere winters are longer and the pressure variation asymmetric. Tracking by the Deep Space Network (DSN) of the Mars Global Surveyor (MGS) spacecraft over 4 Mars years and more recently of the Mars Reconnaissance Orbiter (MRO) spacecraft have been used to study the changes in the seasonal mass deposited in the polar regions each winter. The observed variations show the clear seasonal cycle, similar to the predicted deposition by Mars global circulation models but also suggest additional processes may be involved in the movement of mass during a Mars year. The seasonal effect of loading on the crust and the movement of carbon dioxide in and out of the regolith with the seasons are possible explanations.

The first indicated that Mars once had a dynamo and global magnetic field, now gone; the second indicated that most parts of Mars were much older than we had previously believed. Evidence for the buried impact basins came from MOLA topography in the form of Quasi-Circular Depressions (QCDs), most of which had no visible expression. While crater retention ages derived from visible and buried impacts are likely a closer approximation to the actual age of buried surfaces, those ages would still be minimum ages because there could be basins buried so deeply they would not have an expression in topography alone. Some of those more deeply buried basins may be expressed as Circular Thin Areas (CTAs) in crustal thickness models, derived from MGS topography and gravity data. Many CTAs are coincident with previously mapped QCDs, and the ratio of non-QCD CTAs to QCDs is highest in areas of deepest burial, both of which support the idea that many CTAs may be deeply buried impact basins. Crustal thickness data also reveals the presence of several additional very large impact basins, bringing the total > 1000 km in diameter to 20. The N(300) crater retention ages for these basins, from superimposed CTAs and QCDs, indicate that most of the basins formed in a very brief interval of time, perhaps in only 100 million years. This may be a Martian equivalent of the "terminal lunar cataclysm". More interesting, the brief interval when most of the large basins formed also appears to bracket the time when the martian dynamo died: the 5 least magnetized basins all have N(300) 3.0. The change in crustal magnetic field intensity over this time is a factor 10. The switch from dynamo to "no-dynamo" conditions on Mars may have occurred in less than a few 10s of MY, and, given its association with the "spike" in large basin production on Mars, it is worth considering whether the death of the dynamo may have been prompted by the largest of these impacts, 4 of 5 of which may have occurred in the 60 MY interval just prior to the loss of the magnetic field.

Orsted and CHAMP satellite magnetic observations with greatly improved measurement accuracies and temporal and spatial coverage of the Antarctic, have now supplanted the Magsat data. We combined the new satellite observations with the near-surface survey data for an improved magnetic anomaly map of the Antarctic lithosphere. Specifically, we separated the crustal from the core and external field components in the satellite data using crustal thickness variations estimated from the terrain and the satellite-derived free-air gravity observations. Regional gaps in the near-surface surveys were then filled with predictions from crustal magnetization models that jointly satisfied the near-surface and satellite crustal anomalies.

Resolution of this debate has major implications for the prediction of glacier mass balance, because it determines how rapidly a glacier can respond dynamically to changes such as weakening or removal of an ice shelf. Current IPCC assessment of sea-level rise takes little account of such changes, on the assumption that dynamic responses would be too slow to have any appreciable effect on ice discharge fluxes. However, this assumption must be questioned in view of observations showing massive increases in glacier velocities following removal of parts of the Larsen Ice Shelf, Antarctica, and of others showing diurnal velocity changes apparently linked to the tides. Here, I use a simple force-perturbation model to calculate the response of glacier strain rates to tidal rise and fall, assuming associated longitudinal-force perturbations are transmitted swiftly far inland of the glacier grounding line. Results show reasonable agreement with observations from an Alaskan glacier, where the velocity changes extended only a short distance up-glacier. However, for larger Antarctic glaciers, big velocity changes extending far upstream cannot be explained by this mechanism, unless ice-shelf "back forces" change substantially with the tides. Additional insight will require continuous measurement of velocity and strain-rate profiles along flow lines of glaciers and ice shelves. An example is suggested, involving continuous GPS measurements at a series of locations along the centre line of Glaciar San Rafael, Chile, extending from near the calving front to perhaps 20 km inland. Tidal range here is about + or -0.8 m, which should be sufficient to cause a variation in ice-front velocity of + or -2 cm h (super -1) about its average value of 75 cm h (super -1) , assuming local seawater depth of 150 m and glacier thickness of 200-400 m.

However, our knowledge of the sub-ice crust is very limited due to the paucity of outcrops and seismic observations, particularly in central Greenland. In order to augment these sparse constraints, we modeled terrain and airborne free-air gravity data which provide estimates for Moho and related crustal thickness. These estimates were obtained from the inversion of isostatically corrected terrain effects where the computed gravity effects of the terrain's rock, water, and ice components were subtracted from the terrain-correlated free-air anomalies. The terrain-correlated free-air components were estimated from the correlation spectrum between the free-air anomalies and the terrain's gravity effects which are assumed to reflect isostatic disturbances of the crustal terrain. The results indicated an average crustal thickness of about 37 km for Greenland, with greater values by 5-10 km, in the southern Greenland Archean blocks and Caledonian Foldbelt, and comparably lower values in northern Greenland. The thinner crustal thickness estimates in the north are strongly correlated with the faster basal melt regions of the ice sheet and glaciers. The crustal thickness map provides constraints for an improved interpretation of the Iceland hotspot track in northern Greenland at about 100-70 Ma.

The effort culminated in the participation of 67 nations in research programs from pole-to-pole and out into space and the ultimate benefits remain difficult to assess. In fact, historians of science are still struggling to chart the IGY's origin, plans, and progress missing and/or conflicting information. The IGY Gold History Preservation Initiative strives to assist this effort by identifying IGY participants and gathering materials/resources which could be of significance in reconstructing/rediscovering the IGY's key events and personalities.

Synthetic spectra across a crater topographic profile are created using the modeling results. The synthetic spectra are examined for spectral variations created by changes in lighting conditions induced by the topography. Changes above the modeling uncertainties are seen in both spectral slope and band depths, though the most pronounced change is in band depth. The data have insufficient spectral resolution to determine if there are any changes in band center due to photometric effects. No additional absorption features are introduced by the photometry. These results have serious implications on the interpretation of spectral observations in terms of abundance estimates and alteration processes as a function of location and association with geologic features.

The earth science community can benefit by sharing software assets such as code, applications, documentation, and standards. However, there are also challenges involved in reusing software, and these barriers must be identified and broken down in order to encourage more systematic software reuse. The NASA Earth Science Data Systems (ESDS) Software Reuse Working Group has been chartered to oversee the process that will maximize the reuse of potential software components. As part of this work, we have collected case studies from members of the ESDS Software Reuse Working Group about their experiences in software reuse. This poster will present information from four such case studies, including a comparison of the common issues they faced and how those issues were resolved. The presentation will examine some of the lessons learned by these projects, how they can be used to improve future software reuse efforts, and include a summary of the benefits realized by these projects.

The Gulf-front towns of Holly Beach and Cameron, Louisiana were located within the hurricane's right-front quadrant and suffered near total destruction. In a cooperative program between the U.S. Geological Survey, NASA, University of New Orleans, Louisiana State University and Louisiana Department of Natural Resources, aerial photography and airborne topographic lidar were acquired of the coastal towns and adjacent beach systems of the Chenier Plain, both before and after landfall. These data show erosion and accretion along the coast as well as the near total removal of structures within the impacted communities. The shallow offshore shelf seaward of the Chenier Plain in western Louisiana is conducive to large storm surges along the coast, the surge during Rita reaching approximately 5 m. Beach systems along the Chenier Plain are low relief, their peak elevations generally rising no higher than approximately 2 m above mean high water. As a consequence, during Rita, the entire beach system was not overwashed in the classic sense of waves periodically overtopping a berm or dune, but was continuously submerged, as characterized by the "inundation regime" of Sallenger (2000). In Holly Beach, preliminary analyses of lidar data show that the shoreline retreated on average approximately 18 m, and the beaches lost significant quantities of sand, lowering beach elevations in places >1 m. The low relief of beach systems, coupled with the potential for high storm surges, makes the Chenier Plain of Louisiana one of the United States' most vulnerable coasts to extreme storms.

Past work inferred that it was emplaced via tubes and inflated sheets, although only indirect evidence of tubes was found. Here we discuss field work on the Carrizozo vent region, comprising a low shield approximately 7 by 5 km in diameter, rising up to 60 m above the pre-flow terrain. From the western flow margin, Differential Global Positioning System (DGPS) data show three topographic plateaus increasing to 2, 8, and 10 m, and possibly a fourth at 12 m, above the adjacent terrain across 1.2 km towards the vent. The discontinuous plateaus include lava collapse and rise pits. 30 m/pix Shuttle Radar Topography Mission (SRTM) and DGPS data show that plateaus are typified by <1 degree slopes, except across pit walls where slopes are steeper. SRTM derived slopes increase from 2 to 9 degrees across the next 1.3 km, rising 50 m above the plateau terrain to the summit. The near vent region is typified by more numerous collapse and inflation pits resulting in a less uniform plateau surface. The vent (Little Black Peak) is capped by a approximately 30 m tall cinder pile and small ( approximately 5 m) summit depression. Although Little Black Peak is the prominent summit feature, the vent area appears to comprise a set of three coalesced cinder piles and a perched lava pond. East of the main vent is a collapsed lava tube, exposing a network of three branching tubes that descend into the eastern flow field at different topographic levels. Lava flow textures and structures suggest that the Carrizozo low shield was built through a combination of several tube-fed sheet inflation events, breakouts resulting in small surface lava flows, and several mildly explosive episodes at the vent. The eruption also fed a much more extensive, likely tube-fed lava flow beyond the extent of the primary low shield for 10s of kilometers. Therefore, the bulk of the flow field is located beyond the extent of the Carrizozo low shield. Similar small-vents are seen in clusters on Mars and elsewhere on the Earth. The distribution of lava deposits at Carrizozo suggest that care should be taken when estimating low shield volume or surface area based on remote sensing data alone, particularly if the vent is located within a field of vents where embayment of extensive lava flow fields might have occurred.

The organic detector consists of 3 subsystems, the Sub-Critical Water Extractor (SCWE), Mars Organic Detector (MOD), and @2M-Capillary Electrophoresis instrument (mu -CE). The Mars Oxidant Investigation (MOI) has the capability to independently characterize oxidants within both the atmosphere and regolith. Currently, miniature versions of each component instrument exist as validated field-test units. The Urey flight-instrument has been engineered and a functional full-scale ( approximately 7,000 cm (super 3) ) prototype will be completed within 2 years. The organic detection system utilizes a 2-stage extraction procedure which first liberates organic compounds from the soil or regolith sample using high-temperature high-pressure water (SCWE). Target organics are then isolated via sublimation onto a cold finger (MOD). The analytical system is configured around the mu -CE instrument which separates and analyzes fluorescamine-labeled primary amine compounds. The target amines include several of the major molecular species ubiquitous in terrestrial life such as amino acids, amino sugars, and nucleobases. Naturally fluorescent PAHs can also be separated and quantified. The high sensitivity of the mu -CE system and efficiency of SCWE extraction allow for detection of amino acids from biodensities of approximately 10 (super 3) cells/g in 60mg of sample. The capability of the Urey instrument to detect chiral amino acids will allow discrimination between abiotic formation and biosynthesis by an extant or extinct Martian biota. If proteins and amino acids have been degraded, Urey can resolve various amine decarboxylation products. The cold and dry climate of Mars should have minimized diagenesis of biological materials in the near-surface regolith, allowing biosignature preservation on geological timescales if the samples were adequately protected from radiolysis. Urey has been selected as part of the Pasteur payload for the 2013 ESA ExoMars mission. The proposed drilling capabilities of the ExoMars Rover will allow for the greatest chance of success in the detection of biomolecules characteristic of terrestrial life.

The nature of these small vents and their deposits can provide insight into eruptive styles prevalent during what may have been the last stages of active volcanism on Mars. More importantly, information on the spatial distribution of small vents can be compared to other areas of volcanism to ascertain whether or not significant similarities or differences exist. Any differences may be due to changes in eruptive style as volcanic activity migrated from one volcanic center to the next (Arsia to Pavonis to Ascraeus), or possibly a reflection of the lava distribution systems (influenced by internal plumbing and crustal structure) of the three volcanic centers. In this study, 88 small vents have been systematically identified for a sample area (270 km X 480 km) south of Pavonis Mons. Approximately 45% of the sample area is covered by two adjacent High Resolution Stereo Camera image strips, and approximately 65 % of the remaining sample area is covered by a Thermal Emission Imaging System visible image mosaic. Analysis is based on the distance from each feature to its nearest neighbor (NN) to determine whether the spatial distribution is random and, if so, the character of randomness. The objective is to obtain insight into the underlying formation processes and the possibility of interactions among the neighboring features. The distribution of NN distances for small vents is very well fit by the classic Poison Nearest Neighbor (PNN) distribution, with a mean value of 14.1 km + or - 2 km. Because the distribution is well-described by the PNN, we infer that the spacing of small vents at Pavonis is consistent with a randomly distributed Poisson process. Thus, small vents are equally likely to occur at any location within the sample area, and the existence of any vent does not influence the location of any other vent. Analyses of skewness and kurtosis of the NN distribution also fall within the acceptable ranges for a Poisson process, further supporting the basic inference that vents at Pavonis are spatially random in a Poisson sense. This inference is consistent with the hypothesis that development of each small eruptive vent is fed by independent shallow magma chambers and not driven by a single, centralized plumbing system.

The unique color and stereo data provided by the HRSC has enabled new studies of the formation, evolution, and styles of martian volcanic constructs and processes. Studies have focused on individual edifices/processes, as well as global assessments. Radial valley networks on some volcanoes (Hecates, Ceraunius) appear to be related to magmatic heating and melting of snowpack. Mapping of lava flow morphologies on Olympus Mons and on the Tharsis Montes show an evolution from tube-fed to channel-fed flows, with implications for the nature of the magma source underlying Tharsis. Lava flows on Ascraeus Mons had yield strengths, effusion rates, and eruption durations consistent with Hawaiian volcanoes. Syria Planum was dominated by both swarms of small shields, and a single larger edifice as the source of long lava flows. Finally, the wide areal coverage at consistently high resolution of HRSC images has enabled a chronology of Martian volcanism to be determined using crater statistical methods. We find that Olympus Mons, the Tharsis Montes, and Hecates Tholus likely formed by 3.5 Ga, but have continued to have effusive eruptions throughout Martian history, with multiple caldera-forming eruptions between 100 Ma to 1 Ga. Evidence suggests that the most recent volcanic eruptions on Mars occurred on Olympus Mons, as recently as a few Ma. In contrast, the highland paterae surrounding the Hellas Basin (e.g., Hadriaca & Tyrrhena Paterae) ceased major eruptions prior to 1 Ga. The low-viscosity lavas flooding Gusev Crater (MER Spirit landing site) are 3.65 Ga, and postdate older sediments. Further studies are in progress.

This lake has become the focus of the Pavilion Lake Research Project (PLRP), which is an on-going, multi-disciplinary science effort to understand the existence of unusual microbialites in Pavilion Lake. This project forms part of a NASA-UBC led effort to investigate the analog potential of terrestrial lacustrine carbonates to early Earth and potentially early Mars systems. Here we present an overview of research at Pavilion Lake: a combination of hypothesis and exploration driven research to study the lake's unusual freshwater microbialite structures. The foundation for this study is the seminal work by Laval et al. (2000), which provides an overview of the morphological characteristics of the microbialites, and explores the physical limnology of Pavilion Lake. Several key hypotheses and questions related to the role of biology in the formation of the microbialites, and the effect of varying light levels on the microbialite morphologies have since resulted from Laval et al. (2000), but to date remain untested and unanswered. We are currently revisiting Pavilion Lake to test hypotheses concerning the geobiological factors affecting the microbialite formation, and to collect further exploration data related to understanding the lake's structure and development. In particular, we are (1) investigating the hypothesized biological origins of the microbialites and the controlling input of PAR on their morphological variation, (2) exploring the physical and chemical limnological properties of the lake, especially as these characteristics pertain to microbialite formation, and (3) determining the spectral (visible to thermal infrared) and erosional properties of the carbonates. This presentation will provide an overview of key findings from the current exploration thrust and describe planned future endeavors.

The Gusev coatings may be derived from the dissolution of adhering soil and/or parent rock along with the addition of S and Cl from outside sources. Transient water for dissolution could be sourced from melting snow during periods of high obliquity, acid fog, and/or ground water (Haskin et al., 2005). Coatings on basalt in the hyper-arid (< 2mm y-1) Atacama Desert may assist in understanding the chemistry, mineralogy and formation mechanisms of the Gusev Basalt coatings. The Atacama Desert climate is proposed to be analogous to a paleo-Mars climate that was characterized by limited aqueous activity when the Gusev coatings could have formed. The objectives of this work are to (i) determine the chemical nature and extent of surface coatings on Atacama Desert basalt, and (ii) assess coating formation mechanisms in the Atacama Desert. Preliminary backscattered electron imaging of Atacama basalt thin-sections indicated that the coatings are as thick as 20 Mm. The boundary between the coating and the basalt labradorite, ilmenite, and augite grains was abrupt indicating that the basalt minerals underwent no chemical dissolution. The Atacama coatings have been added to the basalt instead of being derived from basalt chemical weathering. Semi-quantitative energy dispersive spectroscopy shows the coatings to be chemically homogeneous. The coating is depleted in Ca (0.9 wt% CaO) and enriched in K (1.3 wt.% K2O) and Si (69.1 wt.% SiO2) relative to the augite and labradorite grains. A dust source enriched in Si (e.g., poorly crystalline silica) and K and depleted in Ca appears to have been added to the basalt surface. Unlike the Gusev coatings, no P, S, and Cl enrichment was observed. However, Fe (3.2 wt.% FeO) was present in the Atacama coatings suggesting the present of Fe-oxides. While the chemistry of Atacama coating does not mirror the Gusev coating, the coating formation mechanism may be similar. The Atacama coatings of surface basalt are derived completely from exogenous sources. If surface Mars rocks have experienced limited wetting conditions as in the Atacama, then Mars coatings may be derived only from dissolution of material adhering to rock.

In this work we aim to determine a) whether or not such deposits could melt and generate liquid water on Mars and b) whether or not these deposits could be capable of supporting life. To address these questions we are studying snowpack deposits in a Mars analog environment at Lassen National Park. The Lassen snowpacks cycle through yearly stages of accumulation and melt and are sites of snow algae activity. Snow algae on Earth are known to live dormant within the cold polar regions of Earth and become active only during the transient melt season when liquid water is generated from dissipating snowpacks (Hoham 1975, Hoham et al. 1983). The critical factor in the survival of snow algae is a period of time when the snowpack contains liquid water. On Earth this generally occurs in high alpine regions in late spring and summer. At Lassen National Park, the snow algae are preferentially found in locations where the snowpack is large enough to survive long into the summer. On Mars our calculations can indicate if liquid water forms in the snowpack. Our research characterizes this potential habitable abode and thereby assesses the potential for favorable environmental conditions which could allow lifeforms to exist in the near-surface environment of Mars. Here we provide a quantitative assessment of the physical conditions within a terrestrial snowpack in an alpine environment from in situ data. An analysis of this data presents an improved understanding of the physical processes driving the seasonal cycles of accumulation and melt. Numerical modeling helps predict the physical conditions within the snowpack, snowpack stability under various environmental conditions, as well as the timing and magnitude of melt events. We will have utilized this numerical model in conjunction with spacecraft data to model the behavior of snow and ice deposits associated with the gully features on Mars. Our improved understanding of the physics of snowpack behavior and the interplay of ambient environmental conditions allows us to assess the potential habitability of snow and ice deposits on both Earth and Mars to improve our understanding of the biologic potential in such locales.

The recent report from the Intergovernmental Panel on Climate Change (IPCC) demonstrates that policy makers will be relying heavily on such GCM forecasts to assess the potential impacts of various greenhouse gas scenarios on society. However, climate simulation capabilities are not easily disseminated to the majority of researchers--let alone educators, students, or a myriad of other climate change stakeholders--because most GCMs require high-level computing capabilities and programming support. This lack of broad public access, coupled with the ever-increasing complexity of climate models, can lead to misunderstandings and a distrust of simulation results that compromises climate scientists' ability to convey critical findings: findings that could otherwise help determine society's ability to mitigate, adapt to, or even take advantage of, future climate change. The software and educational tool designs created by the Educational Global Climate Modeling Project (EdGCM) are proof that it is possible to put sophisticated computer climate simulation capabilities--not just "demo" software or output from pre-run simulations--into the hands of non-modelers for use in education and research. The ultimate goal of the EdGCM Project is to get crucial climate simulation technologies into the hands of teachers, professors, and all those who are informing the next generation of policy makers and scientists about climate change, so that we have a skilled workforce capable of dealing with the multitude of climate impacts facing society in the 21st century.

Such derivations have led to great insight into the cratering process, yet have typically treated targets as continuous media. In many cases, however, planetary materials represent irregular and discontinuous targets, the effects of which on the scaling relationships are still poorly understood. We continue to examine the effects of varying impact conditions on the excavation and final dimensions of craters formed in sand. This contribution presents some of the data collected during and after the impact of glass and aluminum spheres into medium- and coarse-grained sand targets. Experiments are performed with the Vertical Impact Facility at the Johnson Space Center during which the ejecta were documented with the Ejection-Velocity Measurement System (EVMS). Projectiles impacted the target at speeds ranging from 0.32 to 1.9 km/s and at normal incidence angles. The EVMS produces stroboscopic images of ejecta in flight by flashing a "sheet" of laser light at programmed rates; the illumination sequence initiates at impact, which serves as the reference time for subsequent measurement of particle kinematics. The "sheet" is aligned such that fragments of the target with multiple images in the photograph were traveling radially from the impact site. The velocities of a large number of ejected fragments are measured in each photograph, and those values can be decomposed into their respective speed and launch-angle components. Evolution of ejection speed with crater growth is fit using ejecta-scaling theory and crater size-scaling relationships are applied to the final crater dimensions. Results have implications for the role of target material grain size as well as the mechanism by which the projectile deforms.

The obvious physiographic and especially crater retention age differences were major drivers in promoting endogenic theories for the origin of the lowlands, even though suggestions of ancient impact basins were also reported. Below the surface, the lowland basement may in fact be very similar to the highlands, at least in age. Quasi-Circular Depressions (QCDs) revealed by MOLA data showed hundreds of features that appear to be buried impact craters and which implied a crater retention age for the lowland basement that was substantially older than previously thought, perhaps as old as the exposed and visible highlands. The highlands themselves also have a population of buried impact basins, so based only on topographic expressions of impact basins, the lowlands appeared to be still somewhat younger than the highlands. But crater retention ages based on QCDs alone are likely minimum ages, as there could well be impact basins buried so deeply that no topographic expression remains. Crustal thickness data derived from topography and gravity data reveal Circular Thin Areas (CTAs) which may be deeply buried impact basins. Support for this comes from (a) many of the CTAs are in fact coincident with previously observed QCDs, (b) the ratio of non-QCD CTAs to QCDs is greatest in areas of thickest burial (the lowlands, Tharsis), and (c) cumulative frequency curves including non-QCD CTAs along with QCDs have a similar character to those for QCDs alone. These same curves indicate both the highlands and lowlands are even older than previously thought (based on QCDs alone) and that the lowland basement may be as old as the highland basement. While this has important implications for possible endogenic origins for the lowlands, the same crustal thickness data reveal the presence of more large basins in the lowlands, indicating that impact played a major role in creating the topographic character of the northern third of Mars. Dating of these basins indicates all those in the lowlands, and most of those in the highlands, formed in a brief interval of time, perhaps analogous to the Late Heavy Bombardment on the Moon.

In February and March 2007, the New Horizons spacecraft obtained a global snapshot of Io's volcanism. A 350-kilometer-high volcanic plume was seen to emanate from the Tvashtar volcano (62 degrees N, 122 degrees W), and its motion was observed. The plume's morphology and dynamics support nonballistic models of large Io plumes and also suggest that most visible plume particles condensed within the plume rather than being ejected from the source. In images taken in Jupiter eclipse, nonthermal visible-wavelength emission was seen from individual volcanoes near Io's sub-Jupiter and anti-Jupiter points. Near-infrared emission from the brightest volcanoes indicates minimum magma temperatures in the 1150- to 1335-kelvin range, consistent with basaltic composition.

The inducing EEJ and Sq current systems are provided by the comprehensive model of Sabaka et al. (2004). The three-dimensional (3-D) conductivity model of the Earth includes oceans of laterally variable conductance and a spherical conductor (1-D) underneath. Our model studies demonstrate that induction effects in Z due to the EEJ are negligible everywhere inland for all local times. At CHAMP altitude (400 km) the magnetic signal induced by EEJ above the oceans does not exceed 2-5% of the external field during local noon. This, in particular, means that considering the induction effects is not necessary when modeling the EEJ current strength from inland surface magnetic measurements and/or satellite data. As expected, induction in the oceans strongly affects the Sq field. The model studies show that the anomalous induction effect (defined as the difference between results obtained with 1-D and 3-D conductivity models) of Sq is substantial at CHAMP altitude, comprising 50% of the total field. It is therefore necessary to consider induction in the oceans when modeling Sq variations for both ground-based and satellite data. Finally, we demonstrate that the anomalous behavior of the daily variations in Z at south Indian sites, namely, a large positive prenoon peak, can be explained by 3-D induction of the Sq variations, with no contribution from the EEJ.

No similarly massive carbonates have been detected. We present the results of coupled atmospheric and geochemical calculations of the formation of the sulfate-rich Meridiani sediments, and offer an explanation for why extensive layered carbonates are not found there or elsewhere on Mars. Large scale volcanism from the build-up of Tharsis during the late Noachian would have injected large amounts of SO (sub 2) into the atmosphere. Efficient photochemical conversion of SO (sub 2) to H (sub 2) SO (sub 4) would have caused widespread sulfuric acid/water clouds, similar to those seen on Venus today. Precipitation from these clouds and acidification of surface water would have sustained a thick, warm CO (sub 2) atmosphere via carbonate inhibition. Such an atmosphere could have been subjected to loss to space via impact erosion and sputtering. Once atmospheric SO (sub 2) gas production dropped and waters become more alkaline, the remaining CO (sub 2) in the atmosphere collapsed to form poorly consolidated carbonate patinas on rock surfaces and in open fractures.

Therefore, their formation via non-enzymatic reactions is highly relevant to Gilbert's RNA world scenario (1986) and the origin of life. In laboratory synthesis of oligonucleotides from monomers, it is necessary to remove the water molecules from the reaction medium to shift the equilibrium in favor of oligonucleotide formation, which would have been impossible for reactions that took place in dilute solutions on the early Earth. Model studies designed to address this problem demonstrate that montmorillonite, a phyllosilicate common on Earth and identified on Mars, efficiently catalyzes phosphodiester-bond formation between activated mononucleotides in dilute solutions and produces RNA-like oligomers. The purpose of this study was to examine the sequences and regiospecificity of trimer isomers formed in the reaction of 5'-phosphorimidazolides of adenosine and uridine. Results demonstrated that regiospecificity and sequence specificity observed in the dimer fractions are conserved in their elongation products. With regard to regiospecificity, 61% of the linkages were found to be RNA-like 3',5'-phosphodiester bonds. With regard to sequence specificity, we found that 88% of the linear trimers were hetero-isomers with 61% A-monomer and 39% U-monomer incorporation. These results lend support to Bernal's hypothesis that minerals may have played a significant role in the chemical processes that led to the origin of life by catalyzing the formation of phosphodiester bonds in RNA-like oligomers.

Lakes Chandler, Deborah, and Gilmore, located in Western Australia, are among the rare terrestrial examples of dry lakes hosting evaporite minerals, such as jarosite and alunite, indicative of acidic conditions. The three dry lakes were chosen for study because of differences in local bedrock geology, which is a primary factor affecting brine compositions and related fractionation processes. Specifically, Lake Deborah is unusual in having komatiitic (ultramafic) rocks within its drainage basin, whereas Lakes Chandler and Gilmore are associated with more silicic rocks. Little is known about the distributions of evaporite mineral phases in these systems. Multispectral imagery acquired by the orbital Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), as well as hyperspectral imagery from HyMap, an Australian airborne sensor, are being analyzed to map the evaporite mineralogy. These data are being compared with hyperspectral data of the Martian surface collected by the OMEGA and CRISM orbital imaging spectrometers. Remote sensing information on the spatial distributions of acid playa minerals should help resolve questions concerning sources of acidity and related sedimentary processes, such as calcrete and silcrete development. Evaporite minerals formed near springs along playa margins often are especially interesting as these areas may reflect unusual local inflow sources, as well as brine compositional gradients and zones of mixing. Such hydrochemical gradients typically correspond to gradients in salinity, Eh and pH and offer a broad range of options for biological activity. We seek to answer these questions: Are any of the Martian deposits actual evaporites, or were they formed by some other process? Are there associated features, such as silcretes, which might be linked to aquifer chemistry, and even to possible biological mediation? If some Martian deposits are evaporites formed in playa-like settings, what are the best areas to search for fossil and chemical trace fossil preservation? How can we identify these areas using orbital remote sensing and rovers?

This is particularly true of the Arctic region, where year-to-year variations in planetary wave forcing (and possibly other factors) appear to strongly modulate the possibility for chemical ozone loss. This study will examine temperature and ozone change between about 1960 and 2008 in the Arctic using observations, meteorological analyses, and the Goddard Earth Observing System Chemistry-Climate Model (GEOS CCM). Analysis of observations will re-examine the suggestion of Pawson and Naujokat (JGR, 1999) that there may be a tendency for dynamically undisturbed winters to become colder between 1960 and 2000. Controlled experiments with the GEOS CCM allow examination of the significance of this apparent trend and isolation of possible mechanisms for it.

Ozone recovery is also strongly dependant on transport and temperature, which are significantly different between the middle 21st century and the 1980s due to greenhouse gas increases. This paper investigates changes in transport and their impacts on ozone distributions in the post-CFC era using simulations from the Goddard Earth Observing System Coupled Chemistry-Climate Model. Model simulations of the recent past and the 21st century with projected greenhouse gas increases under the IPCC A1B scenario are analyzed. Model simulations show an enhancement of the Brewer-Dobson circulation with a trend of 3%/decade in tropical upwelling. The accelerated Brewer-Dobson circulation increases the mean ozone transport, resulting in less ozone in the tropics and more ozone in the extratropics. Model results reveal that, in the 2060s when the stratospheric halogen loading recovers to 1980 values, ozone changes below 30 km can be mainly attributed to the enhanced mean advective transport. The total column ozone changes, however, are determined by the combined effects of a stronger mean transport and slower ozone loss reactions arising from upper stratosphere cooling. In the tropics, enhanced upwelling outweighs reduced ozone photochemical losses, and the model projects that tropical total column ozone does not recovery to 1980 values. In the extratropics, enhanced downwelling, combined with ozone increase above 30 km, causes a "super recovery" of ozone. We will also discuss inter-hemispheric differences in the changes of the transport and the contraction of the tropical upwelling.

Detection of the initial stages of recovery has been the topic of a number of recent papers. An important aspect of recovery is the attribution of changes to the removal of ozone-depleting substances. The attribution is complicated by expected changes in stratospheric ozone due to increasing greenhouse gases. We use data from SBUV measurements on Nimbus 7 and the NOAA series of satellites to make a first attempt at observing the different expected time signatures from ozone-depleting substances and greenhouse gases. Ozone depleting substances, as represented by the Equivalent Effective Stratospheric Chlorine (EESC) have now peaked and begun their slow decline. Greenhouse gases, such as carbon dioxide, continue to increase nearly linearly. We examine the data in the upper stratosphere (~1-10 hPa) where the greenhouse gas signature is expected to be nearly constant with latitude, and the lower stratosphere (~25-64 hPa) where the greenhouse gas signature is expected to change sign from ozone decreases in the tropics to ozone increases in the mid to high latitudes. Our goal is to use data to confirm the response of ozone to changes in ozone-depleting substances and to eventually detect the response of ozone to greenhouse gases.

Giovanni, the NASA GES DISC Interactive Online Visualization ANd ANalysis Infrastructure, is a simple-to-use yet powerful tool for research on and application of global warming and climate change, as well as their impacts on such areas as weather, air quality, agriculture, and water resources. Giovanni is an online data system with a remarkable capability for data exploration, basic research, and exemplary data visualization, utilizing data from many different NASA Earth observation missions. With these long-term, high resolution and widely available data sets, including parameters such as temperature, precipitation, and greenhouse gases (water vapor, methane, carbon dioxide, and ozone), Giovanni provides capabilities to facilitate climate change and global warming research. Examples include the computation and visualization of long-term means; the analysis of time series and trends; the study of inter-annual and intra- annual variabilities; and the identification and study of extreme events (e.g hurricanes, floods, droughts, El Nino, La Nina). In addition to images, Giovanni also provides the output data in ASCII, HDF, NetCDF, and KML formats, and exports output images to Google Earth. Giovanni has proven to be a highly successful and popular climate services infrastructure that is significantly contributing to the study of global warming and climate change and their social, political, economic, and environmental issues that affect all of us on this planet.

We focus on several key industrial and urban pollutants: ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO), and sulfur dioxide (SO2) to analyze changes in pollution concentrations over Beijing, as well as other industrialized regions around the world for comparison. We use remote sensing data from NASA's Aura Ozone Monitoring Instrument (OMI) and Terra/Measurements Of Pollution In The Troposphere (MOPITT). Preliminary analysis show a reduction in NO2 concentrations compared to previous years in August. However, changes in the longer lived trace pollutants such as tropospheric ozone, CO and SO2 are less apparent and highly variable due the influence of the regional meteorology. In particular, pollution levels in Beijing depend on whether the prevailing winds are blowing in from the sparsely populated north or from the heavily industrialized provinces to the south, i.e. the nearby Tianjin area and the more southeastern Shanghai region. Preliminary back-trajectory analysis reveal air parcels coming from the south correlate well with high pollution days over Beijing.

In both rural and very polluted situations, we find that a simple "contour graph" parameterization of the local principal ozone production rate can be estimated using only the variables [NO] and j sub(rads) [HCHO]: Po(O sub(3)) = c (j sub(rads) [HCHO]) super(a) [NO] super(b). The method immediately suggests a local interpretation for concepts of VOC limitation and NOx limitation. We believe that the product j sub(rads) [HCHO] gauges the oxidation rate of observed VOC mixtures in a way that also provides [HO sub(2)] useful for the principle ozone production rate k [HO sub(2)] [NO], Mechanisms suggest that ozone production due to RO sub(2) is proportional to the HO sub(2) process, hence we may capture all ozone chemical production. The success of the method suggests that dominant urban primary-HCHO sources may transition to secondary plume-HCHO sources, so that HCHO is never too far away from an evolving steady state with VOC reactivity. Are there other, simple, near-terminal oxidized VOC's which help gauge ozone production and aerosol particle formation? Regarding particles, we report on suggestive relationships between far-downwind (Atlantic PBL) HCHO and very fine aerosol. Since j sub(rads) [HCHO] provides a reactive-flux rate, we may understand distant-plume particle production in a more quantitative manner. Additionally, we report on a statistical search in the nearer field for relationships between glyoxals (important penultimate aromatic and isoprene reaction products) with ozone and aerosol production, looking for VOC's that might be most implicated, e.g aromatics and biogenics. Note that all three of our variables j sub(rads), [HCHO], and [NO] are relatively easily measured in widespread air pollution networks, and all are deducible form space-borne observations. Estimation of [NO] from [NO sub(2)] (the species observable from space) may require care. Wider measurement of HCHO and its reactivity should be key environmental measurements, justifying relatively greater expeditures. Fortunately, the use of the 3.58 micron microwindow for HCHO remote sensing allows more economical resolution of HCHO than other techniques.

Perennial ice is ice that survives the summer and consists mainly of second year and the older multiyear ice types. The rapid rate of decline in the perennial ice cover has been reported and examined previously and with the precipitous decline in 2007 and again in 2008, the Arctic Ocean has become an intense area of climate change result. The perennial ice area in 2007 was observed to be 27% less than the previous record low established in 2005 and was 38% less than climatological average. The sea surface temperature (SST) in the Arctic has also been on the rise at about 0.7 per decade with the SST at the Chukchi Sea region being observed by satellite data to be anomalously higher than average by about 5 oC. This is an indication that ice-albedo feedback effects in the region are already being observed and that a recovery of the perennial ice cover in the foreseeable future may not be possible. To gain insight into the state of the multiyear ice cover, we take advantage of the large contrast in the emissivity of first year and multiyear ice in winter and assess the variability and trend of the older multiyear ice type. The contrast is largest in February when the ice is cold and dry and the technique and is most pronounced between first year and the older multiyear (3 years or older) ice types. The retrieved area of winter multiyear ice is about 2 million km super(2) less than that of the perennial ice area observed during the previous summer indicating that only the older and thicker types of multiyear ice are included. The trend of the retrieved multiyear ice cover for the period 1979 to 2007 is observed to be about -14%/decade which indicates a significantly faster decline than the perennial ice cover. This suggests that the thicker component of the perennial ice cover is declining even more rapidly that the perennial ice. The area and extent of the perennial ice in 2008 appears to be the second lowest if not the lowest during the satellite era. The persistence of low values during the recent decade and especially in 2007 and 2008 is a manifestation of a generally thinner Arctic ice cover in the recent years than in the 1980s. This phenomenon together with the observed rapid rise in SST suggest that the impact of ice-albedo feedback is becoming an important factor that needs to be considered in the changing Arctic.

Comparing the results forced by daily- or monthly- averaged values, we find that the sudden events significantly affect the ocean from bi-weekly to annual changes, with consequences on the Pacific warm pool and beyond. By classifying TRMM data into weather regimes we find that the northward propagation of the Indian ocean signals up to the Bengladesh is linked to the eastward propagation of the MJOs around the Planet.

The original product reports aerosol optical depth and a variety of other aerosol parameters at a spatial resolution of 10 km over both land and ocean. The 10 km product is actually constructed from 500 m pixels, which permits a strict selection process to choose the "best" or "cleanest" pixels in each 10 km square for use in the aerosol retrieval. Thus, the original 10 km product provides a useful product, accurate in many applications. However, the 10 km product can miss narrow aerosol plumes and the spatial variability associated with urban air pollution. The MODIS aerosol team will be introducing a finer resolution aerosol product over land regions in the next release of the product (Collection 6). The new product will be produced at 3 km resolution. It is based on the same procedures as the original product and benefits from the same spatial variability criteria for finding and masking cloudy pixels. The 3 km product does capture the higher spatial variability associated with individual aerosol plumes. However, it is noisier than the 10 km product. Both products will be available operationally in Collection 6. The new 3km product offers new synergistic possibilities with PM2.5 monitoring networks, AERONET and various air quality models such as CMAQ.

The Climate Change Adaptation Task Force is part of PlaNYC, the city's long- term sustainability plan, and is composed of over 30 city and state agencies, public authorities and companies that operate the region's roads, bridges, tunnels, mass transit, and water, sewer, energy and telecommunications systems all with critical infrastructure identified as vulnerable. It is one of the most comprehensive adaptation efforts yet launched by an urban region. To guide the effort, Mayor Michael Bloomberg has formed the New York City Panel on Climate Change (NPCC), modeled on the Intergovernmental Panel on Climate Change (IPCC). Experts on the panel include climatologists, sea-level rise specialists, adaptation experts, and engineers, as well as representatives from the insurance and legal sectors. The NPCC is developing planning tools for use by the Task Force members that provide information about climate risks, adaptation and risk assessment, prioritization frameworks, and climate protection levels. The advisory panel is supplying climate change projections, helping to identify at- risk infrastructure, and assisting the Task Force in developing adaptation strategies and guidelines for design of new structures. The NPCC will also publish an assessment report in 2009 that will serve as the foundation for climate change adaptation in the New York City region, similar to the IPCC reports. Issues that the Climate Change Adaptation Task Force and the NPCC are addressing include decision- making under climate change uncertainty, effective ways for expert knowledge to be incorporated into public actions, and strategies for maintaining consistent and effective attention to long-term climate change even as municipal governments cycle through their administrations.

As a result, the structure and evolution of the PBL contains information directly related to land surface states. To examine the nature and magnitude of land-atmosphere coupling and the interactions and feedbacks controlling PBL development, the authors used a large sample of radiosonde observations collected at the southern Atmospheric Research Measurement Program-Great Plains Cloud and Radiation Testbed (ARM-CART) site in association with simulations of mixed-layer growth from a single-column PBL/land surface model. The model accurately predicts PBL evolution and realistically simulates thermodynamics associated with two key controls on PBL growth: atmospheric stability and soil moisture. The information content of these variables and their influence on PBL height and screen-level temperature can be characterized using statistical methods to describe PBL-land surface coupling over a wide range of conditions. Results also show that the first-order effects of land-atmosphere coupling are manifested in the control of soil moisture and stability on atmospheric demand for evapotranspiration and on the surface energy balance. Two principal land-atmosphere feedback regimes observed during soil moisture drydown periods are identified that complicate direct relationships between PBL and land surface properties, and, as a result, limit the accuracy of uncoupled land surface and traditional PBL growth models. In particular, treatments for entrainment and the role of the residual mixed layer are critical to quantifying diurnal land-atmosphere interactions.

Two flights of the NASA DC-8 are compared and contrasted. Chemical data from the DC-8 flight on 18 July show evidence for interleaving and mixing of polluted and stratospheric air masses in the vicinity of the subtropical jet in the upper troposphere, while on 2 August the DC-8 flew through a polluted upper troposphere and a lowermost stratosphere that showed evidence of an intrusion of polluted air. We compare data from both flights with RAQMS 3-D global meteorological and chemical model fields to establish dynamical context and to diagnose processes regulating the degree of mixing on each day. We also use trajectory mapping of the model fields to show that filamentary structure due to upstream strain deformation contributes to tracer variability observed in the upper troposphere. An Eulerian measure of strain versus rotation in the large-scale flow is found useful in predicting filamentary structure in the vicinity of the jet. Higher-frequency (6-24 km) tracer variability is attributed to buoyancy wave oscillations in the vicinity of the jet, whose turbulent dissipation leads to efficient mixing across tracer gradients.

Subsequently, the discovery of chemical signatures of extinct or extant life in Europa's ocean and on its surface became a distinct possibility. Moreover, understanding of Europa's potential habitability is now one of the major goals of the Europa Orbiter Flagship mission. It is likely, that in the early stages of Europa's ocean formation, moderately alkaline oceanic sulfate-carbonate species and a magnetite-silicate mantel could have participated in low-temperature biogeochemical sulfur, iron and carbon cycles facilitated by primitive organisms (Zolotov and Shock, 2004). If periodic supplies of fresh rock and sulfate-carbonate ions are available in Europa's ocean, then an exciting prospect exists that life may be present in Europa's ocean today. In our laboratory, we began the study of the plausible biogeochemical reactions under conditions appropriate to Europa's ocean using barophilic psychrophilic organisms that thrive under anaerobic conditions. In the near absence of abiotic synthetic pathways due to low Europa's temperatures, the biotic synthesis may present a viable opportunity for the formation of the organic and inorganic compounds under these extreme conditions. This work is independent of assumptions regarding hydrothermal vents at Europa's ocean floor or surface-derived oxidant sources. For our studies, we have fabricated a high-pressure (5,000 psi) reaction vessel that simulates aqueous conditions on Europa. We were also successful at reviving barophilic psychrophilic strains of Shewanella bacterium, which serve as test organisms in this investigation. Currently, facultative barophilic psychrophilic stains of Shewanella are grown in the presence of ferric food source; the strains exhibiting iron reduction capability will be later selected and used to facilitate biogeochemical reduction of iron under simulated temperature and pressure of Europa's ocean. The results of this work will enable us to ascertain whether Europas cold, high-pressure ocean is capable of supporting life. In addition, the data from this study will help in generating a list of organic and inorganic target molecules for future remote sensing and in situ exploration missions.

Here, satellite radar observations are used to produce a composite picture of the life cycle of convection in these two regions. Estimates of the broadband thermal flux from the geostationary Meteosat-8 satellite are used to identify and track organized convective systems over their life cycle. The evolution of the system size and vertical extent are used to define five life cycle stages (warm and cold developing, mature, cold and warm dissipating), providing the basis for the composite analysis of the system evolution. The tracked systems are matched to overpasses of the Tropical Rainfall Measuring Mission satellite, and a composite picture of the evolution of various radar and lightning characteristics is built up. The results suggest a fundamental difference in the convective life cycle between land and ocean. African storms evolve from convectively active systems with frequent lightning in their developing stages to more stratiform conditions as they dissipate. Over the Atlantic, the convective fraction remains essentially constant into the dissipating stages, and lightning occurrence peaks late in the life cycle. This behavior is consistent with differences in convective sustainability in land and ocean regions as proposed in previous studies. The area expansion rate during the developing stages of convection is used to provide an estimate of the intensity of convection. Reasonable correlations are found between this index and the convective system lifetime, size, and depth.

Over the entire watershed, the mean extent of inundation during the snow-free months is 2.6 x 10 super(5) km super(2), consistent with previous independent static or satellites-derived estimates. The maximum in yearly inundation, showing propagation from south to north between April and June, exhibits strong seasonal and inter-annual variations. The consistency of the inundation estimates is then analyzed at local or basin-wide scale using different in situ or satellite- derived snow and runoff parameters. The results show a strong relationship between the inundation extent and the snowmelt date, the snowpack depth at three in situ stations located in the southern part of the basin. Over the northern part, results show that flooding is more closely linked to the amount of water coming downstream from the southern part of the basin. A close systematic relationship is also found between the inundation extent and the local in situ runoff at six locations as well as with the altimeter-derived discharge measured at the Ob estuary. This case study evaluation shows the potential of these data sets to provide consistent information about the seasonal and inter-annual variations of inundation over a major Boreal river basin. These results also suggest new potential to improve the description of the snow-inundation-runoff relationship that are fundamental for climate and hydrological models.

Present examples include potential loss of all Arctic sea ice and instability of the West Antarctic and Greenland ice sheets. Tipping points are characterized by ready feedbacks that amplify the effect of forcings. The notion that these may be runaway feedbacks is a misconception. However, present "unrealized" global warming, due to the climate system's thermal inertia, exacerbates the difficulty of avoiding global warming tipping points. I argue that prompt efforts to slow CO2 emissions and absolutely reduce non-CO2 forcings are both essential if we are to avoid tipping points that would be disastrous for humanity and creation, the planet as civilization knows it.

AN - 20622681; 7588265 AB - The intensity of moist convection is an important diagnostic of climate change not currently predicted by most climate models. We show that a simple estimate of the vertical velocity of convective updrafts in a global climate model reproduces observed land-ocean differences in convective intensity. Changes in convective intensity in a doubled CO sub(2) simulation are small because the tropical lapse rate tends to follow a moist adiabatic profile. However, updrafts strengthen by similar to 1 m s super(-1) with warming in the lightning-producing regions of continental convective storms, primarily due to an upward shift in the freezing level. For the western United States, drying in the warmer climate reduces the frequency of lightning-producing storms that initiate forest fires, but the strongest storms occur 26% more often. For the central-eastern United States, stronger updrafts combined with weaker wind shear suggest little change in severe storm occurrence with warming, but the most severe storms occur more often.

Using an antecedent precipitation index (API) as a proxy of antecedent moisture conditions, this note estimates time-varying NRCS-CN values determined by the 5-day normalized API. Driven by a multiyear (1998-2006) Tropical Rainfall Measuring Mission Multi-satellite Precipitation Analysis, quasi-global runoff was retrospectively simulated with the NRCS-CN method and compared to Global Runoff Data Centre data at global and catchment scales. Results demonstrated the potential for using this simple method when diagnosing runoff values from satellite rainfall for the globe and for medium to large river basins. This work was done with the simple NRCS-CN method as a first-cut approach to understanding the challenges that lie ahead in advancing the satellite-based inference of global runoff. We expect that the successes and limitations revealed in this study will lay the basis for applying more advanced methods to capture the dynamic variability of the global hydrologic process for global runoff monitoring in real time. The essential ingredient in this work is the use of global satellite-based rainfall estimation.

Enhancement ratios and emission factors for HCOOH, CH sub(3)OH, HCN, C sub(2)H sub(6), and OCS relative to CO at 250-350 hPa are inferred from measurements of young plumes compared with lower mixing ratios assumed to represent background conditions based on a CO emission factor derived from boreal measurements. Results are generally consistent with the limited data reported for various vegetative types and emission phases measured in extratropical forests including boreal forests. The low correlation between fire product emission mixing ratios and the SF sub(6) mixing ratio is consistent with no significant SF sub(6) emissions from the biomass fires.

Whole-body vibration training (WBVT) is intentional exposure to WBV to increase leg muscle strength, bone mineral density, health-related quality of life, and decrease back pain. The purpose of this study was to quantitatively evaluate vibration exposure and biodynamic responses during typical WBVT regimens. Methods: Healthy men and women (N = 16) were recruited to perform slow, unloaded squats during WBVT (30 Hz; 4 mm sub(p-p)), during which knee flexion angle (KA), mechanical impedance, head acceleration (Ha sub(rms)), and estimated vibration dose value (eVDV) were measured. WBVT was repeated using two forms of vibration: 1) vertical forces to both feet simultaneously (VV), and 2) upward forces to only one foot at a time (RV). Results: Mechanical impedance varied inversely with KA during RV (effect size, eta super(2) sub(p): 0.668, P < 0.01) and VV ( eta super(2) sub(p): 0.533, P < 0.05). Ha sub(rms) varied with KA ( eta super(2) sub(p): 0.686, P < 0.01) and is greater during VV than during RV at all KA (P < 0.01). The effect of KA on Ha sub(rms) is different for RV and VV ( eta super(2) sub(p): 0.567, P < 0.05). The eVDV associated with typical RV and VV training regimens (30 Hz, 4 mm sub(p-p), 10 min times d super(-1)) exceeds the recommended daily vibration exposure as defined by ISO 2631-1 (P < 0.01). Conclusions: ISO standards indicate that 10 min times d super(-1) WBVT is potentially harmful to the human body; the risk of adverse health effects may be lower during RV than VV and at half-squats rather than full-squats or upright stance. More research is needed to explore the long-term health hazards of WBVT.

These two factors give rise to significant inaccuracies whenever a single grid area average soil wetness value is inserted into a stress function to calculate the evapotranspiration rate for a large grid area. A numerical method is presented to mitigate this problem. The distribution of soil wetness within a grid area is represented by binning, and a numerical integration of the stress function over this binned distribution provides a spatially integrated wetness stress term for the whole grid area, which permits calculation of grid area fluxes in a single operation. The method is very accurate when 10 or more bins are used. It can deal realistically with spatially variable precipitation, conserves moisture exactly, strongly reduces any oscillations, and allows for precise modification of the soil wetness distribution after every time step.

In the next 5,000 years agricultures developed independently in at least six regions of the world. It is virtually certain that it was not a chance occurrence that so many new agricultures appeared in the same 5,000 years. What inhibited agriculture world wide for 44,000 years and what changed similar to 10,000 years ago? Here we suggest that a major factor influencing the development of agricultural societies was climate stability. From the experience of four cultures we estimate that the development of agriculture needed similar to 2,000 years of climate free from significant climate variations on time scales of a few centuries. Using the Empirical Mode Decomposition technique specifically designed to exhibit the time history of the amplitude of variations in non-stationary time series such as climate proxy records, we find that between 50,000 years ago and the termination of the Younger Dryas similar to 11,600 years ago there was probably no time span as long as 2,000 years that was free of relatively large century scale variations. Furthermore variations on these time scales appear to have been relatively small since the Younger Dryas (YD) ended, supporting our proposition concerning the importance of climate stability in the history of human culture.

Up to date, no systematic methods are available to provide aerosol vertical profiles except lidar technology. However the current satellite-based lidar measurements are limited to a narrow line when satellite overpasses. It would need an ensemble of lidar measurements collected from a period of time or from multi-platforms to cover a region such as the United States. With one snapshot, the MODIS-estimated aerosol (top) layer height (hereinafter aerosol height) can provide the 1st order approximation of the vertical extent of aerosol loading derived from the visible spectrum, giving a virtual 3-D view of pollution transported from source to downwind regions. Aerosol height index is developed to show a relative measure between near-surface (aerosol index=0) and elevated aerosol layers (aerosol height index = 2). Aerosol height is estimated to intercompare with ground-based, air- and space-borne lidar measurements. In addition to INTEX-A field campaign period (July 1 August 15, 2004), a suite of pollution events from 2000 to 2007 will be illustrated in detail along with meteorological fields and trajectory analyses. The immediate applications, in addition to air quality monitoring, include smoke injected height of forest fires (for modeling purpurse) and the conversion of aerosol optical depth to PM2.5 mass concentration.

Relevant data products include MODIS Aerosol Optical Depth (AOD), CALIOP aerosol information, and PM sub(2.5) and ozone surface monitor data. Giovanni services include maps, time series, Hovmoller plots, statistical analysis of one or more data sets for a selected region, and image animations of satellite data. For A-Train sensors, Giovanni is capable of providing vertical profile information for various atmospheric components measured along the A-Train orbit tracks. Additionally, the capability to generate AOD/PM sub(2.5) correlation maps, a research tool for understanding the utility of satellite data for monitoring U.S pollution at various temporal and spatial scales, has been added to the Giovanni system. We present several high pollution events in U.S based on these Giovanni analysis and visualization tools. On August 1-5, 2007 a combination of local pollution sources, long range transport of smoke from Canada and the U.S northwest, and hot and humid conditions lead to a high PM sub(2.5) event over the eastern half of the continental U.S. CALIOP profile data from Giovanni are used here to analyze the vertical transport of the pollution plumes and to better understand the satellite observations and the relative contribution of the various pollution sources to surface PM sub(2.5) concentrations. In the spring of 2007, large wildfires occurred in Georgia and Florida. During the active burning period, Atlanta experienced seven PM sub(2.5) National Ambient Air Quality Standard (NAAQS) exceedances, most occurring during May. Correctly predicting air quality during a wildfire can be difficult, as shown by the missed Air Quality Index (AQI) forecasts for those exceedance days. We use ground- based and multi-satellite data to characterize the impact of these fires on air quality in the Atlanta metropolitan area. The AOD/PM sub(2.5) correlations in conjunction with data on optical properties of urban aerosols and meteorological conditions are examined to determine satellite value-added information for improving air quality modeling in urban areas.

The HSRL instrument measures profiles of aerosol extinction, backscatter and depolarization. The height of the Planetary Boundary Layer was derived by identifying sharp gradients in the HSRL 532-nm aerosol backscatter signal profiles using an automated technique based on Brooks (2003) [I.M. Brooks, Finding Boundary Layer Top: Application of Wavelet Covariance Transform to Lidar Backscatter Profiles. Journal of Atmospheric and Oceanic Technology 20, 1092-1105, 2003]. The technique uses a Haar wavelet covariance transform with multiple wavelet dilation values to adapt to non-ideal conditions where there can be gradients in the background signals and the boundary layer can be ill defined. The technique also identifies the top and bottom of the transition (i.e. entrainment) zone. We have further modified the algorithm to find PBL heights using HSRL backscatter data acquired during GoMACCS and MILAGRO, where complex terrain and overlying aerosol layers further complicate identifying the boundary layer. In addition, PBL heights are derived from HSRL backscatter data acquired during the CHAPS campaign, in another urban environment where the terrain is not as complex. We will describe the algorithm modifications we have made and show boundary layer heights and transition zone thicknesses for HSRL measurements over the Oklahoma City, Houston, and Mexico City areas during CHAPS, TexAQS/GoMACCS, and MILAGRO.

The Fourth Assessment Report of the IPCC estimates that direct radiative forcing due to all aerosols is a cooling of -0.50 W m-2 with absorbing aerosol (black carbon) responsible for a warming of +0.22 W m-2, but the uncertainties associated with these numbers are very large. Better measurements of the optical properties of aerosols, especially absorption coefficient and asymmetry parameter, and their spatial and temporal distribution are required to reduce these uncertainties and improve the ability of models to predict climate change. Aero3X was designed to provide such measurements. It is a light weight (11 kg), compact (0.25 x 0.30 x 0.6 m), and fast (1 Hz sample rate) instrument intended for use on Unmanned Aerial System (UAS) but suitable for flight on other aircraft and for surface measurements. Aero3X uses an off-axis cavity ring-down technique to measure extinction coefficient and a reciprical nephelometry technique for measurement of total-, forward- and back-scatter coefficients at wavelengths of 405 nm and 675 nm. Its outstanding precision (0.1 Mm-1) and sensitivity (0.2 Mm- 1) allow the determination of absorption coefficient, single-scattering albedo, estimates of backscatter to extinction ratio and asymmetry parameter at both wavelengths, and Angstrom exponent. Together with its humidification system for measurement of the dependence of aerosol optical properties on relative humidity, these represent a complete set of the aerosol optical properties important to climate and air quality. Aero3X was designed to operate in pollution plumes where NO2 may cause interference with the measurement, therefore, a measurement of NO2 mixing ratio is also made. The paper will cover the main points of instrument design and present performance data obtained in Ames Research Center labs with calibration aerosol and at Lawrence Berkeley Laboratory with black carbon aerosol. A comparison with more standard instrumentation will be presented. A theoretical study showing that the combination of measurements made by Aero3X can give a rough idea of aerosol composition will also be presented.

The cities of Houston and Dallas are both in violation of the EPA air quality standard for 8-hour concentration of surface ozone. The Texas Commission on Environmental Quality (TCEQ) uses the CAMx air quality model to study scenarios for reducing emissions to bring the state into agreement with EPA requirements. The results from the model analyses are incorporated into the State Implementation Plan (SIP) that provides the detailed procedures by which the state will improve air quality in the future. We present preliminary results in trying to use satellite data to understand how the air quality models are doing in the free troposphere and in regions where there are no ground station data available. We will focus on the use of TES data to evaluate ozone and carbon monoxide fields from CAMx and outline our plans to incorporate data from AIRS and other satellite instruments into the analysis.

Coastal subsidence exacerbates these overall impacts. In the New York City metropolitan area, rates of relative sea level rise for the last 100 years range between 2-4 mm/yr, to which ongoing glacial isostatic adjustments (GIA) contribute on average ~40 %. While this percentage diminishes as climate-induced sea level trends increase, it remains non-negligible. We apply Ramstorf's (2007, Science, 315, 368-370) semi-empirical methodology that links global temperature change to sea level rise for IPCC SRES A1B, A2, and B1 greenhouse gas emission scenarios, using World Climate Research Programme (WCRP) Coupled Model Intercomparison Project phase 3 (CMIP3) dataset for 11 global climate models. Sea level projections are corrected for GIA, using Peltier's ICE-5G 1deg x 1deg gridded dataset. Projected global sea level rise by the end of the 21st century ranges between 48 and 94 cm above the 2001-2005 base period. Projections of regional sea level rise encompassing the New York metropolitan region will be presented. An importance consequence is the increase in flood hazards even with small increments of sea level and constant storm climatology. For example, in New York City, a flood event with a current recurrence interval of 1 in 10 years, is likely to occur once a year or less by the 2080s.

One of the goals of this mission was to better understand the behavior and distribution of water in the TTL, which is important to climate through the greenhouse effect and the radiative impact of clouds. Here, we present new measurements of water vapor in the TTL measured by the JPL Laser Hygrometer (JLH) on the WB-57 aircraft during TC4. JLH utilized both harmonic and direct-absorption spectroscopy to measure water vapor. JLH water vapor profiles are compared with EOS MLS satellite retrievals as well as the Cryogenic Frostpoint Hygrometer. These results have been verified by recent laboratory measurements by JLH. We will discuss the implications of these profiles for theories of cloud formation in the TTL.

These measurements are made globally at urban scale resolution with no inter-orbital gaps that make them potentially very useful for air quality research, such as the determination of the sources and processes that affect global and regional air quality, and to develop applications such as air quality forecast. However, the use of satellite data for such applications is not as straightfoward as satellite data have been for stratospheric research. There is a need for close interaction between the satellite product developers, in-situ measurement programs, and the air quality research community to overcome some of the inherent difficulties in interpreting data from satellite-based remote sensing instruments. In this talk we will discuss the challenges and opportunities in using OMI products for air quality research and applications. A key conclusion of this work is that to realize the full potential of OMI measurements it will be necessary to combine OMI data with data from instruments such as MLS, MODIS, AIRS, and CALIPSO that are currently flying in the "A-train" satellite constellation. In addition similar data taken by satellites crossing the earth at different local times than the A-train (e.g., the recently MetOp satellite) would need to be processed in a consistent manner to study diurnal variability, and to capture the effects on air quality of rapidly changing events such as wild fires.

Most previous studies of past and future O sub(3) changes have neglected the influence of aerosol-cloud interactions. We apply the NASA Goddard Institute for Space Studies model for Physical Understanding of Composition- Climate INteractions and Impacts (G-PUCCINI) to quantify the impact of aerosol-cloud interactions on O sub(3) radiative forcing and surface air quality for the 2030 A1B future atmosphere relative to 1995. Aerosols simulated include sulfate, organic carbon, black carbon, sea-salt and dust. The aerosol-cloud interactions simulated for liquid-phase stratus and cumulus clouds include (1) the first aerosol indirect effect: increased (decreased) cloud reflectivity due to an increase (decrease) in aerosols and cloud droplet number concentrations and reduced (increased) droplet sizes: and (2) the second aerosol indirect effect: change in cloud cover, cloud liquid water path and precipitation due to smaller droplet sizes that inhibit precipitation processes. For 2030 relative to 1995, the aerosol indirect effect is -0.69 Wm-2 mainly due to increases in cloud liquid water path at the expense of suppressed precipitation leading to increases in cloud optical depth. The global annual mean O sub(3) radiative forcing across this time period is +0.126 Wm-2, 10% less than for experiments that do not consider aerosol-cloud interactions. Our results imply that aerosol-cloud interactions have limited the O sub(3) forcing since the preindustrial. When aerosol-cloud interactions are included, simulated surface O sub(3) at 2030 is decreased across the United States and South Asia and increased across Europe, around 1-2 pbbv on the annual mean. We use the model to explore the effect of the observed global decrease in reflective aerosol since 1990 on tropospheric O sub(3) despite the counteracting influence of air quality control legislation on O sub(3) precursors in the United States and Europe, and the simultaneous decline in the methane growth rate across the same time period.

AN - 20242760; 8326983 AB - Resolution of important outstanding questions in air quality, climate change and ozone layer stability demands global observations of multiple chemical species with high horizontal and vertical resolution from the boundary layer to the stratopause. We present a mission concept that delivers the needed atmospheric composition observations, along with cloud ice and water vapor data needed for improvements in climate and weather forecasting models. The mission comprises ultraviolet and infrared nadir and microwave limb viewing instruments observing wide swaths each orbit. We review the scientific goals of the mission and the measurement capabilities this concept will deliver. We describe how precessing orbits offer significant improvements in temporal resolution and diurnal coverage compared to sun-synchronous orbits. Such improvements are needed to quantify the impact of critical "fast processes" such as deep convection on the composition and radiative properties of the upper troposphere, a region where water vapor and ozone are strong but poorly understood greenhouse gases. This concept can serve as the "Global Atmospheric Composition Mission" (GACM) recently recommended by the National Academy of Sciences decadal survey as one of 17 priority earth science missions for the coming decade.

Absorbed solar radiation is the energy input to the Earth-atmosphere system, while thermal radiation emitted to space is the sink. Global energy balance, modulated by clouds, aerosols, absorbing gases, atmospheric and ocean heat transports, and their interacting heat capacities, produces the prevailing climate at the Earths surface. Radiative heating and cooling determines the atmospheric temperature distributions which in turn provide the ultimate driving force behind atmospheric motions. The physics of radiative transfer is well understood, so that in principle, accurate heating and cooling rates could be calculated for any specified state of the atmosphere. The task of the GCM radiative transfer model is to perform these calculations fast enough to be practical in climate simulations, while retaining as much of the attainable accuracy as possible. For tractability, the physical realism of the model atmosphere is described in terms of idealized plane-parallel geometry. The GCM radiation model also provides diagnostic information by means of which the GCM performance can be evaluated against available observations. These objectives can be achieved using the correlated k-distribution for modeling thermal radiation, and the single gauss point doubling/adding for modeling solar radiation. Results show that CO2 is the principle non-condensable core-component of the terrestrial greenhouse, accounting for about 20 per cent of the total (33 K) terrestrial greenhouse effect, while the principal feedback components, water vapor and clouds, account for about 50 and 25 per cent, respectively. In the context of current climate, doubled CO2 by itself increases the terrestrial greenhouse by 1.2 K, while feedback contributions, due primarily to water vapor, add an additional 1.5 K.

Important data fields include total and tropospheric column densities, as well as collocated data for cloud fraction and cloud top height, surface albedo and snow/ice coverage, at the resolution of the OMI instrument (12 km * 26 km, at nadir). The retrieved NO sub(2) data have been validated, principally under clear-sky conditions. The first public-release version has been available since September 2006. An improved version of the data product, which includes a number of new data fields, and improved estimates of the retrieval uncertainties will be released by the end of 2007. This talk will describe the standard NO sub(2) data product, including details that are essential for the use of the data for air quality studies.

Using one year of OMI and SLAMS/NAMS ground based data from the EPAs Air Quality System (AQS), NO2 values are compared using a variety of statistical techniques including a time series analysis at each EPA ground station in the continental United States, a site-by- site correlation analysis, site-by-site comparison of mean and standard deviation values, and regional (defined by the ten EPA regions) spatial statistics. In addition, a multivariate statistical prediction model with significance testing is developed to determine within a 95% confidence level the impact of concentration, latitude, region, season, environment (urban vs. rural), and pixel size on the correlation of OMI to EPA NO2 data. The robustness of the statistical model is evaluated using statistical methods. Results of this experiment quantify the ability to use OMI-derived NO2 observations to provide predicted surface concentrations to augment the coverage of the existing NO2 ground networks in regions of sparse or non-existent ground monitors. This predictive capability could facilitate a more capable and integrated observing network for NO2 and lead to more informed air quality management decisions at the local, state, and national level.

Air quality agencies currently use ground monitoring sites to monitor air quality in the San Joaquin Valley. This method provides accurate information at specific points but does not provide a clear indication of what is occurring over large regions. Using measurements from satellite imagery has the potential to provide valuable air quality information in a timely manner across large regions. While previous studies show good correlations between satellite derived Aerosol Optical Thickness (AOT) and surface PM measurements on the East Coast of the United States, the data do not correlate well in the SJV. This paper compares PM sub(2.5) ground data from the California Air Resources Board (CARB) and the Interagency Monitoring of Protected Environments (IMPROVE) sites with satellite data in an effort to understand this discrepancy. To verify satellite AOT value accuracy, ground AOT values were collected from the Aerosol Robotic Network (AERONET) and from measurements using the hand-held MicroTops II Sun Photometer field instrument. We found good correlation of the AOT values between MODIS, MISR and AERONET. However, we found poor correlations between satellite- based AOT values and PM sub(2.5) values, and consideration of aerosol speciation did not improve the correlations. Further investigation is needed to determine the causes of the poor correlation. Acquiring detailed information on the meteorological conditions and vertical profiles of the atmosphere using ground-based LIDAR or data from CALIPSO may provide better results.

AOD provides column integrated aerosol loading which is supplemental to the ground-based in-situ measurements. Monitoring atmospheric loadings of dust and smoke and their subsequent transport using MODIS AOD has been found to be particularly effective, because these aerosol species are frequently transported aloft and not observed by ground-based in-situ networks. Air quality models have become a powerful tool to diagnose and predict three- dimensional distributions of aerosol species. The model performance with dust and smoke is, however, not as good as that with sulfate aerosol. This is because dust and smoke events are episodic and it is difficult to characterize their emissions. Consequently, these aerosol constituents introduce large uncertainties in modeled aerosol distributions. Assimilation of MODIS AOD within an aerosol forecast model makes it possible not only to understand the current aerosol distribution but also to predict it with constraints from the satellite observations. This study presents an assessment of the improvement in aerosol predictions due to the incorporation of MODIS AOD in a regional aerosol forecast model. The Real-time Air Quality Modeling System (RAQMS) with a MODIS AOD assimilation is used to simulate the aerosol distributions for Aug - Oct, 2006, when dust is being transported from Sahara to the Gulf of Mexico and smoke is emitted from biomass burning over the Pacific Northwest. The model performance is evaluated using the CALIPSO observations for assessing vertical profiles and the EPA AIRNow data for assessing the surface distribution. An impact of the MODIS AOD assimilation on each aerosol species is analyzed. Further improvement of the MODIS AOD assimilation is also discussed.

Such intercontinental transport extends the impact of aerosols for climate change, air quality, atmospheric chemistry, and ocean biology from local and regional scales to hemispheric and global scales. Long term, measurement-based studies are necessary to adequately assess the implications of these wider impacts. A satellite-based assessment can augment intensive field campaigns by expanding temporal and spatial scales and also serve as constraints for model simulations. Satellite imagers have been providing a wealth of evidence for the intercontinental transport of aerosols for more than two decades. Quantitative assessments, however, became feasible only recently as a result of the much improved measurement accuracy and enhanced new capabilities of satellite sensors. In this study, we generated a 4-year (2002 to 2005) climatology of optical depth for pollution aerosol (defined as a mixture of aerosols from urban/industrial pollution and biomass burning in this study) over the North Pacific from MODerate resolution Imaging Spectro-radiometer (MODIS) observations of fine- and coarse-mode aerosol optical depths. The pollution aerosol mass loading and fluxes were then calculated using measurements of the dependence of aerosol mass extinction efficiency on relative humidity and of aerosol vertical distributions from field campaigns and available satellite observations in the region. We estimated that about 18 Tg/year pollution aerosol is exported from East Asia to the northwestern Pacific Ocean, of which about 25% reaches the west coast of North America. The pollution fluxes are largest in spring and smallest in summer. For the period we have examined the strongest export and import of pollution particulates occurred in 2003, due largely to record intense Eurasia wildfires in spring and summer. The overall uncertainty of pollution fluxes is estimated at about 80%. A reduction of uncertainty can be achieved with a better characterization of pollution aerosol through integrating emerging A- Train measurements. Simulations by the Goddard Chemistry Aerosol Radiation and Transport (GOCART) and Global Modeling Initiative (GMI) models agree quite well with the satellite-based estimates of annual and latitude- integrated fluxes, with larger model-satellite differences in latitudinal variations of fluxes.

We summarize the types of applications that are being attempted, discuss the successes that have been achieved, and outline the limitations of the data. Column amounts of the trace gases O3, NO2, SO2, HCHO and aerosol optical depths from OMI are being used for estimating emissions, for assimilation into air quality forecast models, and in analyzing the impacts of major source regions. Profiles of CO and O3 from TES are being used in analyses of long range transport of air pollutants and the air quality impacts of megacities and boreal fires. Assimilation of OMI ozone data into an air quality prediction system has proven successful. Limitations of the Aura data include inadequate temporal sampling, relative insensitivity to boundary layer pollution, limited vertical profile information, and cloud interference. All of these limitations must be carefully considered when applying the Aura data for air quality purposes. Possible future expansion of Aura data applications will be discussed.

It is predicted that fire frequency, area burned, fire severity, fire season length, and severe fire seasons will increase under current climate change scenarios. Already, there is evidence of an increased number of extreme fire seasons in Siberia that correlate with current warming. Our overall goal is to explore the degree to which current and future climate variability has and will affect wildfire-induced land cover change and to highlight the significance of the interaction between the biosphere and the climate system. Developing reliable weather and climate data provides the backbone of this research, which is to examine the relationships between weather, extreme fire events, and fire-induced land cover change in the changing climate of Siberia. The primary focus in this presentation is the description of the assembled weather and climate data sets and the verification efforts, followed by an example where the data set is used in a fire prediction application. Ground- based weather observations from the National Climatic Data Center (NCDC) for the years 1983-2006, have been used to verify various modeled meteorological parameters from the NASA Goddard Earth Observing System version 4 (GEOS-4) data. Specifically, we have extracted "Summary of the Day" and "Integrated Surface Hourly (ISH)" weather data from the NCDC. The ISH data has been processed to obtain hourly observation times for all stations in Siberia, including Mongolia and parts of northern China. A subset of these stations have been selected for validation purposes if they meet a criteria of having at least 75% of the possible reporting observations per day and 75% of the possible days in each month. GEOS-4 data interpolated to a 1x1 degree grid have compared well with the NCDC station data, covering the burning season from April through September and for the entire 1983-2006 period. In cases where large differences exist between the NCDC station and the GEOS-4 grid elevations, lapse rate corrections have been applied to the temperature parameters. With the declining number of Siberian surface observation stations through the 1983-2006 period, using GEOS-4 data ensures data coverage over the entire Siberian region and through the entire data set period. One advantage of the GEOS-4 data is that it is consistent and spatially explicit, which makes it easily portable to multiple data applications or models. One such application being used in this study is the Canadian Forest Fire Weather Index (FWI) System developed by the Canadian Forestry Service. Using local noon values of air temperature, relative humidity, wind speed, and daily rainfall as input, the FWI assesses the conditions of forest fire burning potential for the day. Typically, local weather observation stations supply these meteorological parameters. In Siberia, the density of stations is limited; hence results may not be representative of the spatial reality. GEOS-4 data, on the other hand, provides complete temporal and spatial coverage. Using the GEOS-4 meteorological data as input into the FWI, the generated indices compare well with large and small fires in the 1983 to 2006 timeframe.

Current global warming theory asserts that when the atmospheric concentration of CO2 increases, the outgoing longwave radiation at non-window wavelengths is reduced. If the Earths net radiative balance is to remain stable, ground temperatures must rise in response, thereby increasing thermal emission to space. Current models do not account for subsequent changes in cloud cover, because this aspect of the climate feedback system is so poorly understood. One possible response of the cloud-climate feedback process is an increase in the global occurrence of thin cirrus clouds, driven by the increase in longwave cooling in the upper troposphere that results from higher CO2 concentrations. Exacerbating the difficulty of assessing the situation is the fact that passive remote sensing instruments cannot reliably detect cirrus clouds with optical depths less than similar to 0.3, because these clouds do not reflect enough sunlight to create a sufficient contrast with the Earths surface. Now, however, the presence of thin cirrus can for the first time be accurately detected and systematically monitored by the combination of active and passive sensors onboard the CALIPSO satellite. Nevertheless, the data record is still quite limited, as CALIPSO has been in orbit for only 16 months. We have therefore initiated a multi-platform data fusion study to establish a methodology for extending the limited set of CALIPSO measurements to the existing 30-year record of passive remote sensing data, and thus improve our understanding of cloud feedback mechanisms. Using nighttime data from the first 10 days in April 2007 as a training set, we applied a general regression neural network (GRNN) to collocated samples of sea surface temperature (SST) reported by AMSR, brightness temperatures (BT) from the CALIPSO imaging infrared radiometer (IIR), and optical depths (OD) derived from the CALIPSO lidar measurements. The result is an accurate mapping of the optical depths derived from the active sensors to the brightness temperatures computed from the passive sensor measurements. Applying the trained network to this combination of passive sensor parameters, optical depths as small as 0.1 can be reliably retrieved. The relative uncertainties in the retrieval are reasonable, and can be improved significantly by use of a much larger training set.

One of the more difficult directions has been the study of biochemical material in deep glacial ice and in subglacial lakes. Lake Vostok in Eastern Antarctica has been perhaps the most discussed subglacial lake because of its large size (~14,000 sq km), deep location under >3700 m of overlying ice, and thick sediment bed (~200m). Once the physical conditions of the Lake were assessed, questions immediately arose about the potential existence of biological material - either extinct or possibly extant under conditions of extremely limited energy and nutrients [1-2]. To investigate the biology of Vostok, via in-situ methods, is a major issue that awaits proven techniques that will not contaminate the Lake beyond what may have occurred to date. Lake Ellsworth, in West Antarctica, also discovered by ice penetrating radar, is of significantly smaller size, but is also >3500 m below the overlying ice. It represents a wonderful opportunity to design, engineer and build in-situ delivery systems that consider bio-cleanliness approaches to enable examination of its water, sediment bed and the "roof" area accretion ice for biochemicals [3]. Our laboratory has been developing deep UV fluorescence and UV Raman instrumentation to locate and classify organic material at a variety of extremophile locations. The confluence of the measurement techniques and the engineering for high external pressure instrument shells has enabled us to design and begin prototype fabrication of a biochemical sensing probe that can be inserted into a hot-water drilled ice borehole, functioning as a local area mapper in water environments as deep as 6000 m. Real-time command and control is conducted from a surface science station. We have been using the deep Vostok ice cores at the U.S. National Ice Core Lab to validate our science and data analysis approaches with an "inverted" system that has recently generated spatially resolved spectral images of material inside the Vostok cores without extraction or disturbance to the material in the ice. We will describe the instrumentation we will have available for the British Antarctica Survey Lake Ellsworth Exploration field campaign, provide a possible operational scenario and show examples of the kinds of possible measurement results that might be obtained, based upon our Lake Vostok core studies.

This is Tropospheric Infrared Mapping Spectrometry, TIMS. Lockheed Martin has demonstrated echelle technology and a low-noise IR detector in application to carbon monoxide, methane, and water using a grating mapping spectrometer in the lab and in the field. A key idea is focus on narrow, very informative spectral regions and a scanning technology; in low Earth orbit, the only moving part is calibration, or in GEO, a standard scanner. A change of echelle-grating order allows a focus on the 3.57 micron region, allowing determination of total ozone column, formaldehyde column with lower-troposphere vertical information, methane, and nitrous oxide (a useful atmospheric-column measurement). A variant of the design operating near 400 nm would provide extremely compact NO sub(2) measurements, thus allowing compact (8 cm diameter) UV devices to be added as useful companions. Robust, inexpensive, rapidly deployable ozone monitoring is thus proposed going far beyond the expectations of the recent Earth Science Decadal Survey of remote sensing possibilities and needs. Our current research emphasizes the published utility of NO sub(2) and HCHO sensing in defining ozone production and its complex emissions sensitivities. The form of the technology implies that variety of options exist, from a rapid-launch, inexpensive 3.57 micron O sub(3)-HCHO device to a very compact full-suite complement including more CO, CH sub(4) and NO sub(2) information suitable for geostationary orbit. We also mention that careful statistics using full-column measurements and atmospheric thermal structure information from sounders like AIRS or IASI allow a focus on lower tropospheric ozone with little need for a separate stratospheric-ozone device (SBUV, MLS, HIRDLS). Tropospheric chemistry missions can considerably cut in cost and development time; this is important given the EPAs recent emphasis on the human and economic toll of smog ozone, one justifying stricter standards and a broader regional and international focus.

However, because its spatial and temporal resolutions are low relative to other hydrological observing systems and because total terrestrial water storage is a variable unfamiliar to hydrologists, GRACE has yet to become a standard tool for hydrology. Land surface models (LSMs) simulate the redistribution of water and energy incident on the land surface, but their accuracy is limited by the quality of the input data used to parameterize and force the models, the model developers' understanding of the physics involved, and the simplifications necessary to depict the Earth system economically. The advantages of GRACE and LSMs can be harnessed by data assimilation, which synthesizes discontinuous and imperfect observations with our knowledge of physical processes, as represented in a LSM. The model fills observational gaps, provides quality control, and enables data from disparate measurement systems to be merged, while the observations anchor the results in reality. We have assimilated TWS anomalies derived from GRACE into the Catchment LSM. The experimental domain was the Mississippi River Basin. Monthly GRACE estimates were derived for each of the four major sub-basins. Assimilation was performed using an Ensemble Kalman smoother. In addition to simulating soil and snow water storages, the Catchment LSM accounts for variations in the elevation of the water table, making it appropriate for total terrestrial water storage applications. The assimilated results produced groundwater storage time series which more closely resembled piezometer based estimates, relative to the open loop (non-assimilating) simulations. These results emphasize the potential for GRACE to improve the accuracy of hydrologic model output, which will benefit water cycle science and water resources applications. Furthermore, data assimilation enables coarse resolution, vertically integrated terrestrial water storage anomalies from GRACE to be spatially and temporally disaggregated and attributed to different levels of the snow-soil-aquifer column in a physically meaningful way.

Typically, observational data like those from EOS instruments MISR (the Multi-angle Imaging SpectroRadiometer) and MODIS (the Moderate Resolution Imaging Spectrometer) are massive, distributed at different physical locations, and heterogenous: their observation grids are not coincident either with each other or with model grids. The usual strategy for comparing such disparate data sets is to aggregate the high-resolution observations to a coarse common spatial and temporal resolution that matches that of the model. For example, one may compare IMPACT (the Integrated Massively Parallel Atmospheric Chemical Transport model) output, which are daily predictions of aerosol optical depth (aod) by aerosol particle type, on a one-degree spatial grid, to averages of MISR and MODIS optical depths for the same grid cells on the same days. However, this makes no use of the distributions of optical depth provided by both MISR and MODIS in those grid cells. To compare IMPACT predictions to MISR and MODIS, we conduct hypothesis tests by grid cell and day, testing whether IMPACT predicted values could arise from statistical populations represented by the MISR and MODIS data distributions. The Aerosol Measurement and Processing System (AMAPS), a distributed scientific computing environment for aerosol science, makes it possible for us to carry out these tests on a large scale. In this talk, we report the results for a global, full-year (2001) analysis.

This enhanced flow of continental ice to the ocean contributes directly to global sea level rise and emphasizes the need for improved understanding of ice shelf evolution in a warming climate. An important, but not yet thoroughly examined, factor in ice shelf stability is the extent of marine ice presence, and its effect on shelf flow and mechanical integrity. The Brunt Ice Shelf on the east coast of the Weddell Sea presents a rare setting of rafts of meteoric ice being embedded in large, visible expanses of an ice melange largely composed of marine ice. Different crystallographic structure and salinity and impurity contents should give marine ice a distinct rheology. In this work, we use satellite radar interferometric observations to infer the spatial distribution of the Brunt Ice Shelf ice rheology (flow law parameter B) by an inverse control method. We test the hypothesis of meteoric and marine ice bodies composing the ice shelf having different rheologies, and examine how this distribution affects ice shelf flow and its mechanical competence. We further use the inferred rheology distribution to locate the zones of weakness in the ice shelf, many of which are cut by large rifts filled with a melange, and their influence on ice shelf stability. The outcome of this study makes it possible to better constrain the rheology of ice shelves known to have significant marine ice sections when velocity measurements are not available, while the methods applied demonstrate the importance (and difficulty) of deriving realistic rheologies to simulate ice shelf flow by numerical methods reliably. This work was performed at the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration, Cryospheric Sciences Program.

To do so, we analyze results from a 5-year stratosphere and troposphere simulation from the Global Modeling Initiative (GMI) Chemical Transport Model (CTM) for 1994- 1998 and a 10-year simulation using the GEOS Chemistry Climate Model (GEOS CCM) for 1995-2004. The later includes a tagged CFC-12 tracer to track the transport of aged stratospheric air into the troposphere. We compare the simulated CFC-12 with 10 years surface CFC-12 measurements at two NOAA-GMD sites, Alert and Barrow. We compare O3 with 10 years of ozonesondes at Alert, Eureka, and Resolute. CFC-12, HCl and O3 are all compared with satellite observations from the Advanced Composition Explorer (ACE) and several MkIV balloon measurements in the Arctic. The GEOS CCM and GMI CTM simulations capture well the observed magnitude and annual cycle of CFC-12, HCl, and O3 in the stratosphere and troposphere. Since CFC-12 is emitted at the surface and destroyed in the stratosphere while HCl and O3 are produced in the stratosphere, the stratospheric air shows strong correlation between HCl and O3 and anti-correlation between CFC-12 and O3. We use the CFC-12 tagged tracer to track the transport from the stratosphere to the troposphere and the subsequent transport into the lower troposphere in the Arctic. HCl is paired with O3 to quantify the stratospheric contribution to O3 in the troposphere by applying a scaling factor to the simulated HCl using the HCl-O3 regression ratio. O3 and its annual cycle in the upper troposphere are dominated by stratospheric influence, which peaks in spring. The stratospheric contribution decreases as altitude decreases, accompanied by a delay in the phase of maximum. In the middle troposphere (2-6km), the stratospheric contribution peaks during the summer and is comparable to that of net photochemistry.

AN - 20025036; 8330271 AB - With growing observational awareness of numerous ice-stream processes occurring on short time and spatial scales, e.g., sub-ice-stream lake volume changes and grounding-line sediment wedge build-up, the question of how well models based on "reduced-order" dynamics can simulate ice-stream behavior becomes paramount. Reduced-order models of ice-streams are typically 2-dimensional, and capture only the largest-magnitude terms in the stress tensor (with other terms being constrained by various assumptions). In predicting the overall magnitude and large-scale pattern of ice-stream flow, the reduced-order models appear to be adequate. Efforts underway in the Glaciological Community to create 3-dimensional models of the "full" ice-stream stress balance, which relax the assumptions associated with reduced-order models, suggest that a cost/benefit analysis should be done to determine how likely these efforts will be fruitful. To assess the overall benefits of full 3-dimensional models in relation to the simpler 2-dimensional counterparts, we present model solutions of the full Stokes equations for ice-stream flow over a variety of basal perturbations (e.g., a sticky spot, a subglacial lake, a grounding line). We also present the solutions derived from reduced 2-dimensional models, and compare the two solutions to estimate effects of simplifications and neglected terms, as well as to advise on what circumstances 3-dimensional models are preferable to 2-dimensional models.

Freeboard is combined with snow depth on the sea ice from AMSR-E passive microwave data and nominal densities of snow, water, and sea-ice, to estimate sea-ice thickness. Sea-ice freeboard and thickness distributions show clear seasonal variations which reflect the yearly cycle of the growth and decay of the Weddell Sea pack ice. During the Antarctic winter (Oct-Nov), sea ice grows to its seasonal maximum both in area and thickness, filling in the Weddell Sea. For the four winter periods, the mean freeboards are between 0.33 and 0.41 meters and the mean thicknesses are between 2.1 and 2.2 meters. During the Antarctic summer (Feb-Mar), thinner sea ice melts away, sea ice is mainly distributed in the west Weddell Sea near the Antarctic Peninsula. For the five summer periods, the mean freeboards are 0.34 to 0.45 meters and the mean thicknesses are 1.6 to 2.1 meters. During the Antarctic fall (May-Jun), large areas of new, thinner sea ice forms over the Weddell Sea. For the three fall periods, the mean freeboards and thicknesses vary from 0.26 to 0.28 and 1.3 to 1.5 meters, respectively. The interannual differences in freeboard and thickness in three different seasons, the area and volume for each period are also described. This study demonstrated the ability of satellite laser altimetry to monitor sea-ice mass balance, an important indicator of climate change.

Following a severe storm, there is an urgent need to assess the impact on timber growth so resources can be targeted to assist in recovery. It is also important to identify these damaged areas due to their increased risk of fire and susceptibility to invasive species. Current methods of detection involve assessment through ground-based field surveys, aerial surveys, computer modeling, space- borne remote sensing, and Forest Inventory and Analysis field plots. This project focuses on a need for methods that are at once more synoptic than field surveys and more closely linked to the phenomenology of tree loss and damage than passive remote sensing methods. The primary concentration is on the utilization of Ice, Cloud, and land Elevation Satellite (ICESat) data products to detect changes in forest canopy height as an indicator of post- hurricane forest disturbances. ICESat is a NASA spaceborne lidar mission that utilizes green and infrared light to determine land surface vertical structure in 70m elliptical footprints. While created to primarily measure polar ice sheet mass and cloud property information, it has proven successful in measuring forest canopy height. By analyzing ICESat data over areas affected by Hurricane Katrina, this study demonstrates that ICESat may serve as a useful indicator of a storm's direct effects as well as its long term consequences.

MATCH-MPIC model results using tagged CO tracers demonstrate how changes in this circulation lead to increased influence of emissions from China and southeast Asia on upper tropopsheric O3 over India during ENSO conditions. The impact of ENSO is further demonstrated in the correlation between the anomaly in tropospheric ozone residual data derived from TOMS and the velocity potential anomaly over north India and the equatorial Indian Ocean associated with convective uplift and transport through Walker cells.

Climate response to solar radiative forcing is poorly understood, and previous to SORCE there has been limited information about the spectral character of solar variations. Variations in total solar irradiance (TSI) have contributions from spectral bands ranging from the ultraviolet, through the visible, to the near infrared. These three solar spectral regions, UV, VIS, and NIR, force the stratosphere, troposphere, and ocean mixed layers, respectively. UV is responsible for stratospheric heating, and formation of the ozone layer; VIS heats the Ocean Mixed layer and drives upper oceanic circulation; and NIR directly heats the troposphere by water vapor absorption, as well as through cloud and other feedbacks. In this study, we use a simple 1D radiative convective model (RCM) (Arking, 2005) to study the response of surface and atmospheric temperatures to the spectral forcing of solar radiation as observed by the Spectral Irradiance Monitor (SIM) on SORCE. Preliminary RCM results show significant differences in surface temperature when driven by the SIM spectral solar irradiance (SSI) as compared to responses to SSI variations assumed in previous climate studies (e.g., Kurucz and Bell, 1995).

Ocean surface current patterns impact our lives through their influences on the weather, climate, commerce, natural disasters and sea life. The Ocean Motion web site provides inquiry based, classroom ready materials for high school teachers and students to study ocean surface currents. In addition to the information resources posted on the website, there are also investigations that lead students to explore patterns and relationships through data products (color- coded map images, time series graphs and data tables). These investigations are done through an interactive browser interface that provides access to a wealth of oceanography data. This presentation focuses on use of surface current data and models in student investigations to illustrate application of basic science principles found in high school science curriculum. Skills developed using data to discover patterns and relationships will serve students in other courses as well as empower them to become stewards of the Earths environment.

In addition, TES has a variety of special modes that provide denser spatial mapping at the expense of reduced coverage. One of these modes (called "transect") has now been used to detect additional molecules indicative of regional air pollution. On July 10 2007 at about 05:37 UTC (13:24 LMST) TES conducted such a transect observation over northeast Asia between latitudes +37.988 & +41.998, east longitudes 117.014 & 115.746 (some 460 km long). Examination of the spectral residuals (observed calculated) following the retrieval of the TES standard products revealed surprisingly strong features attributable to enhanced concentrations of ammonia (NH3) and methanol (CH3OH), well above the normal background levels. This is the first time that these molecules have been detected in nadir viewing measurements that penetrate into the lower atmosphere.

Since those observations have begun in late 2003 and 11 repeats of each profile have now been completed, a number of smaller lakes along East and West Antarctic ice streams have also been detected and described. However, because of the size of these large lakes as well as the Recovery Lakes relationship to the acceleration of ice into the Recovery Glacier, an assessment of their lake levels has immediate relevance to broader climate studies. Our study uses the same repeat altimetry technique to assess elevation changes at these two major subglacial lake sites. Because the elevation changes in these lake basins are not expected to be as large as the changes found under ice streams, this effort will rely on the sub-3 cm shot-to-shot precision of ICESat's laser altimeter. And to compensate for inexact repeat profiles that cross the subglacial lake topography at varying locations and angles, cross track slopes will be modeled to try to detect small but significant elevation changes. Any trends at these locations can then be evaluated in terms of lake level and potential for broader climate impact.

Maximum gas phase NOx fluxes and ratios simulated for spring and summer range from similar to 4.0 * 104 to similar to 5.0 * 105 molecules cm-3 s-1 and similar to 0.84 to 1.86, respectively. The model incorporates the appropriate actinic light spectrum, thereby properly weighting the different rates of photolysis of and . This is important since the immediate precursor for NO, for example, absorbs at wavelengths longer than nitrate itself. Finally, one-dimensional model simulations indicate that both gas phase and exhibit a negative concentration gradient as a function of height although [NO]:[NO2] are approximately constant.

Recent flowline modeling study indicates that the thinning during ICESat period is due to about 35% ice dynamic response to the increased seasonal basal sliding induced by surface meltwater and this dynamic thinning-rate increases about an order of magnitude from ERS period to ICESat period. A 3-dimensional ice flow model is developed with incorporation of the seasonal basal sliding induced by the penetration of surface meltwater through ice-sheet moulins and crevasses. The surface meltwater is determined based on the satellite observed surface temperature during the time period of 1982 -2006. The model is applied to the Greenland ice sheet to estimate the dynamic thinning caused by surface meltwater enhancing basal sliding, which provides a mechanism for rapid dynamic response of the ice sheet to climate change.

Remote ozone and aerosol profiles were simultaneously measured below and above the DC-8 to provide information from near the surface to above the tropopause along the flight track. Multiple-wavelength aerosol backscatter measurements were made to estimate the relative size of the aerosols, and simultaneous aerosol depolarization measurements were made to detect the presence of nonspherical aerosols, such as mineral dust. In situ measurements of ozone were also made onboard the DC-8, and these were used to constrain the interpolation of the nadir and zenith ozone lidar measurements, which then provided an estimate of the entire tropospheric ozone profile along the flight track. Large-scale measurements of tropospheric ozone and aerosol distributions were obtained on all INTEX-B flights over the Pacific, and the long-range transport of aged and relatively fresh Asian pollution was often observed in the free troposphere in eastern Pacific. Comparisons have been made between the measured ozone cross sections and results from chemical transport models, which show general agreement in the atmospheric structure and pollution layer features. Average latitudinal and longitudinal variations of ozone and aerosols have also been derived from the remote and in situ ozone data for INTEX-B, and these results are compared to previous field experiments. The contribution of stratosphere-troposphere exchange to the latitudinal variation of ozone over the Pacific has also been examined. This paper discusses these results and relates them to chemical and dynamical processes that produce the observed large-scale variations in ozone and aerosols over the Pacific.

We focus here on some of the most recent measurements and analysis conducted at this site. The relationship between aerosol inversions with cloud fraction and relative humidity will be presented. Using AERONET data for aerosol inversions and Long-Ackerman for cloud fraction, it will be shown that cloud fraction correlates better than relative humidity versus aerosol inversion except in the course volume, although relative humidity demonstrate good relationships as well. Angstrom Exponent (AE 500-870) and Aerosol Optical Thickness (AOT 500) with cloud fraction will also show similar results bearing strong relationships. Cloud conditions play an important role on insolation. Cloud fraction was used to infer the percentage of the sky covered by clouds (clear, partly cloudy or overcast) at the COVE site. Being a warm, humid site in the summer, the annual trend will be discussed where the summer months tend to be the least clear while the fall months being the most clear. Derived Micro-Pulse Lidar (MPL) lowest cloud base height data and statistics will also be shown. Aerosol climatology at this location indicate AOTs and AEs that are consistent with polluted urban aerosols, which is not surprising given the predominantly westerly winds passing over Virginia Beach and Norfolk, VA. Although this is the case, there is a small percentage of clean maritime air indicating that coarse mode aerosols also influence the COVE site. Back trajectories and Angstrom exponent data will be discussed to show this influence.

These measurements provide information on the vertical and horizontal distribution of atmospheric pollutants. High concentrations of these pollutants come principally from motor vehicle exhaust, coal and oil combustion, refineries, and biomass burning. These gases play a major role in the formation of unhealthy ground level ozone (or smog) and can trigger serious respiratory problems. The convective transport of these gases, smoke and dust also pollute the upper troposphere and lower stratosphere where the residence time of these pollutants is relatively long and atmospheric winds transport these pollutants to far distances across the oceans and continents. This presentation provides some examples of how Aura data can be used in monitoring air quality by identifying sources of air pollution and understanding the distribution of these pollutants as they get transported extensive distances from their source. In this study we have also used the Aerosol Index data from TOMS, CO data from MOPITT and AIRS, Aerosol data from MODIS, Aerosol layer height information from CALIPSO, and wind information from the NCEP/NCAR reanalysis. This study uses the web based data exploration and analysis tool Giovanni developed at the NASA Goddard Earth Sciences Data Services and Information Center (GES DSIC). Giovanni provides easy access to satellite data, eliminating the need to download large data sets and thus saving the user time. Giovanni capabilities include on- line animations of 2D maps, time-series plots (including statistics), several combinations of 2D cross-section maps (latitude/longitude/height/time), scatter plots, correlation maps, and collocated subsets of the data along CALIPSO tracks.

AN - 20008131; 8326726 AB - We investigate the modulation of aerosols by the Madden-Julian Oscillation (MJO) using satellite-based global aerosol products, including aerosol index (AI) from the Total Ozone Mapping Spectrometer (TOMS) on Nimbus-7, and aerosol optical thickness (AOT) from the Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra and Aqua and the Advanced Very High Resolution Radiometer (AVHRR) on NOAA satellites. A composite analysis is performed for boreal winter, and the global pentad rainfall data from the NOAA Climate Prediction Center (CPC) Merged Analysis of Precipitation (CMAP) are used to identify MJO events. The MJO composites exhibit large variations in the TOMS AI and MODIS/AVHRR AOT over the equatorial Indian and western Pacific Oceans where MJO convection is active, as well as the tropical Africa and Atlantic Ocean where MJO convection is relatively weak but the background aerosol level is relatively high. A strong inverse linear relationship between the TOMS AI and rainfall anomalies, but a weaker, less coherent positive correlation between the MODIS/AVHRR AOT and rainfall anomalies, were found. The Aerosol Robotic Network AOT pattern at Kaashidoo (73.5degE, 4.9degN) and Nauru (167degE, 0.5degS) is more consistent with MODIS and AVHRR. These results indicate a connection between the MJO, its associated rainfall and circulation variability, and the observed aerosol variations. Several physical and non-physical factors that may contribute to the observed aerosol-rainfall relationship, such as aerosol humidification effect, wet deposition, surface wind speed, phytoplankton, different sensor sensitivities (absorbing versus non-absorbing aerosols and upper versus lower tropospheric aerosols), sampling issue, and cloud contamination, are discussed. However, a clear causal explanation for the observed patterns remains elusive. Further investigation is needed to unravel this complex aerosol-rainfall relationship.

Although many of the physical parameters retrieved from passive satellite radiances, such as atmospheric soundings, have long had direct application in weather and climate studies, the continued development of new uses for RT in deriving new and enhanced parameters often goes unnoticed. This paper explores recent developments in satellite remote sensing that have direct application to problems related to air safety. Aircraft icing is one of the leading causes for air traffic accidents and its occurrence and impact can be minimized by identifying when and where icing conditions are likely to occur. Since icing requires the presence of supercooled water clouds and, often, large water droplets, icing conditions can be deduced from retrievals of cloud phase, optical depth, and effective droplet size. RT parameterizations have been used for many years to retrieve those parameters, but it has only been possible in recent years to determine them in near-real time so that they can be practically used to help warn air traffic about the probability of icing at a given location. Because air traffic is continuous over the course of the day, geostationary satellite data are the suitable means for monitoring aircraft icing conditions. Icing clouds also occur underneath upper-level cirrus clouds and can go undetected using traditional retrieval methods. By using a set of new two-layer cloud model parameterizations together with recently developed multilayered cloud detection techniques, it is possible to evaluate the low-level clouds in multilayered cloud conditions. These techniques and examples of their application using data from the Twelfth Geostationary Operational Environmental Satellite (GOES-12) in the NASA Langley Real-Time Cloud Analysis System will be presented along with validation of the retrieved results. Outstanding problems and future applications will be discussed.

In contrast, few corollary spatial landscape studies exist for microorganisms, particularly in extreme environments. To address this gap, we mapped the abundance and spatial distribution of photoautotrophs colonizing translucent rocks in several sites in the Atacama Desert, including the hyperarid core. Cyanobacterial communities at all sites are predominantly (>=75%) perilithic (confined to the periphery of rocks) and occur in non-random spatial patterns (island patches) at multiple scales. Cyanobacterial patches typically contain 1-5 colonized rocks but in some cases support much higher numbers. A high resolution mapping of a single 18-m super(2) rock cluster at the Aguas Calientes study site (25 capital sigma , 69 Omega ) revealed colonization of 5.2% (49 of 948 quartz rocks) and showed colonized rocks to be much larger ( similar to 2X) than the available mean rock size. Ripleys K and point pattern analyses show that quartz rocks are not selected or occupied by cyanobacteria randomly, but that non- random processes distinct from those creating the background rock pattern must be invoked to explain microbial patchiness in the Atacama Desert. These processes include physical controls (rock size/orientation, microtopography) that reflect resource (water) limitations, and biological dispersal via rainfall, fog and wind.

Biomass burning emissions are typically prescribed on a monthly base in most global chemistry and transport models (CTMs). We investigated the sensitivity of global aerosol transport and distribution to the diurnal cycle, synoptic variability, and vertical injection height of biomass burning emissions. Global simulations of aerosols were conducted using the GEOS-Chem global 3-D chemistry and transport model for summer 2004, with the aforementioned constraints imposed on the 8-day Global Fire Emissions Database (GFED v2). The diurnal cycle was determined using active fire data. The synoptic variability, which depends on temperature, relative humidity, and wind speed, was derived from a fire model. The injection height was derived from MISR smoke plume stereoheights. Model results, with monthly or 8-day (with or without the additional constraints) biomass burning emissions, were compared with aerosol optical depths (AOD) from MISR/MODIS/OMI and the AERONET network, and (mass) concentrations from the IMPROVE network and the INTEX-NA aircraft campaign. Using 8-day instead of monthly biomass burning emissions significantly improves the comparison of mass concentrations of BC, OC, and sulfate with observations. The inclusion of diurnal cycle, synoptic variability, and vertical injection height in the 8-day biomass burning emission inventory lead to more efficient transport of aerosols out of the boundary layer, resulting in lower aerosol loadings over the biomass burning source regions and higher loadings downwind, compared with simulations with monthly inventory. The inclusion of the additional constraints also reduces the discrepancies, both in magnitude and daily variability, between observed and simulated aerosol optical depths (AODs), especially downwind of the biomass burning source regions.

This change has been so pervasive and progressed so rapidly, compared to natural processes, scientists refer to it as "the great transformation". Urbanization or the 'gray wave' of this transformation is being increasingly recognized as an important process in global climate change. A hallmark of our success as a species, large urban conglomerates do in fact alter their environments so profoundly that the local climate, atmospheric composition, and the basic ecology of the landscape are affected in ways that have consequences to human health and economic well-being. Fortunately we have incredible new tools to observe and understand these processes in ways that can be used to plan and develop enjoyable and sustainable urban places. A suite of Earth observing satellites is making it possible to study the interactions between urbanization, biological processes, and the atmosphere including weather and climate. Using these Earth Observatories we are learning how urban heat islands form and potentially ameliorate them, how urbanization can affect rainfall, pollution, surface water recharge at the local level, and climate and food security globally.

These intense boreal fires are very energetic and may inject a large amount of carbon monoxide (CO) and fire-associated aerosols into the upper troposphere and stratosphere through a pyro-convection process. Accurate simulation of lofting height of these fires is challenging. In this study, we evaluated a parameterization of plume lofting by dry and moist convection in the NCAR Community Atmospheric model (CAM) driven by NCEP meteorological data. This allows studies of individual fire- weather events. Our simulations are focused on the Alaska-Yukon boreal fires observed by MOPITT (Measurements of Pollution in The Troposphere) and AIRS (Atmospheric InfraRed Sounder) satellites during the summer of 2004. We will compare the simulated CO with AIRS and MOPITT measured CO. We will also present the effectiveness of a plume-rise parameterization, developed originally for subtropical application, in the simulation of plume height.

We sought to create biogeologic maps through survey traverses across the desert using a rover carrying biologic and geologic instruments. Elements of our science approach were to: Perform ecological transects from the relatively wet coastal range to the arid core of the desert; use converging evidence from science instruments to reach conclusions about microbial abundance; and develop and test exploration strategies adapted to the search of scattered surface and shallow subsurface microbial oases. Understanding the ability of science teams to detect and characterize microbial life signatures remotely using a rover became central to the project. Traverses were accomplished using an autonomous rover in a method that is technologically relevant to Mars exploration. We present an overview of the results of the 2003, 2004, and 2005 field investigations. They include: The confirmed identification of microbial habitats in daylight by detecting fluorescence signals from chlorophyll and dye probes; the characterization of geology by imaging and spectral measurement; the mapping of life along transects; the characterization of environmental conditions; the development of mapping techniques including homogeneous biological scoring and predictive models of habitat location; the development of exploration strategies adapted to the search for life with an autonomous rover capable of up to 10 km of daily traverse; and the autonomous detection of life by the rover as it interprets observations on-the-fly and decides which targets to pursue with further analysis.

During the Life in the Atacama (LITA) 2004 field experiment, satellite imagery and ground-based rover data were used in concert with a follow-the-water exploration strategy to target regions of biological interest in two (1 coastal, 1 inland) desert study sites. Within these regions, environments were located, studied and mapped with spectroscopic and fluorescence imaging (FI) for habitats and microbial life. Habitats included aqueous sedimentary deposits (e.g., evaporites), igneous materials (e.g., basalt, ash deposits), rock outcrops, drainage channels and basins, and alluvial fans. Positive biological signatures (chlorophyll, DNA, protein) were detected at 81% of the 21 locales surveyed with the FI during the long-range, autonomous traverses totaling 30 km. FI sensitivity in detecting microbial life in extreme deserts explains the high percentage of positives despite the low actual abundance of heterotrophic soil bacteria in coastal (-1-10 super(4) CFU/g-soil) and interior (-1- 10 super(2) CFU/g-soil) desert soils. Remote habitat, microbial and climate observations agreed well with ground-truth, indicating a drier and less microbially rich interior compared to the relatively wetter and abundant biology of the coastal site where rover sensors detected the presence of fog and abundant surface lichens. LITA project results underscore the importance of an explicit focus by all engineering and science disciplines on microbially relevant scales (mm to nm), and highlight the success of satellite-based and follow-the-water strategies for locating diverse habitats of biological promise and detecting the microbial hotspots within them.

On-board fluorescence imaging of six biological signatures (e.g., chlorophyll, DNA, proteins) was used to assess abundance, based on a percent positive sample rating system and standardized robotic ecological transects. The percent positive rating system scored each sample based on the measured signal strength (0 for no signal to 2 for strong signal) for each biological signature relative to the total rating possible. The 2005 field experiment results show that percent positive ratings varied significantly across Site D (coastal site with fog), with patchy zones of high abundance correlated with orbital and microscale habitat types (heaved surface crust and gravel bars); alluvial fan habitats generally had lower abundance. Non-random multi-scale biological patchiness also characterized interior desert Sites E and F, with relatively high abundance associated with (paleo)aqueous habitats such as playas. Localized variables, including topography, played an important, albeit complex, role in microbial spatial distribution. Site D biosignature trends correlated with culturable soil bacteria, with MPN ranging from 10-1000 CFU/g-soil, and chlorophyll ratings accurately mapped lichen/moss abundance (Site D) and higher plant (Site F) distributions. Climate also affected biological patchiness, with significant correlation shown between abundance and (rover) air relative humidity, while lichen patterns were linked to the presence of fog. Rover biological mapping results across sites parallel longitudinal W- E wet/dry/wet Atacama climate trends. Overall, the study highlights the success of targeting of aqueous-associated habitats identifiable from orbital geology and mineralogy. The LITA experience also suggests the terrestrial study of life and its distribution, particularly the fields of landscape ecology and ecohydrology, hold critical lessons for the search for life on other planets. Their applications to robotic sampling strategies on Mars should be further exploited. JF - Journal of Geophysical Research. G.

The Atacama Desert is among the most important ones. Sixty-two, non-paired, meteorites have been collected in different places of Atacama since the late 19th century to date. Practically all types, classes and groups of meteorites have been recovered. In this work a review of the Atacama meteorites is carried out, listing all past recoveries, determining the principal strewnfield distribution patterns and providing a general overview of the features of the find locations. Principal find locations are concentrated in the Atacama Central Depression. Most of them coincide with ancient mining industries (metallic or non-metallic) or are located near towns, rail stations, tracks or human settlements. Whatever the meteorite find location was, all meteorite samples were collected on the desert surface and normally: (1) showed more than a quarter of their body exposed; (2) underwent some sign of terrestrial weathering; (3) stone meteorites have a brownish desert-varnish on hand specimen; (4) are non-oriented pieces and (5) are commonly members of a greater mass distributed in a certain place. The distribution of find locations in Atacama Desert is not as simple as it would seem on a first approach, as Atacama salt phases (environmental conditions and mineralogical alterations) have a crucial importance on meteorites weathering.

A suite of aerosol instruments were installed on the DC-8 to measure the number concentrations, optical properties, and size distributions of aerosols and clouds. Flights were flown out of Fairbanks, Alaska during the spring of 2008 and out of Cold Lake, Canada during summer 2008. The spring flights measured instances of Arctic haze which result from the long range transport of pollution from mid-latitude source regions. We investigate the possible prevalence and radiative influence of ice clouds in these haze events. During the summer deployment, flights were flown to characterize emissions from Canadian forest fires. Both fresh and aged fire plumes were sampled in order to determine the impact of this source on the Arctic atmosphere. Aged Siberian and California forest fire plumes were also sampled. In this presentation, we document and contrast the microphysical and optical properties of aerosols from the different sources and examine how these properties change as a function of plume age and cloud processing.

AN - 1093430094; 11690199 AB - Forests store about 45% of terrestrial carbon and affect global climate through complex biogeochemical and biogeophysical processes. Past research has tended to focus on the biogeochemical processes, such as how afforestation and deforestation affect global warming through carbon cycling. Recent studies have started to consider how changes of radiative forcing due to disturbance (biogeophysical feedback) affect the climate. Several recent publications have reached a similar conclusion that the climate impacts of forest disturbance and regrowth differs for tropical, temperate and boreal forests in large part due to differing albedo responses. However, additional analysis of observations is needed to better quantify these differences, especially considering the large-scale implications for climate mitigation through land management. In this presentation, we will examine albedo changes caused by forest disturbance and regrowth from historical Landsat data and the MODIS albedo product from different regions and times. The forest disturbance maps from Landsat data are used to determine the disturbed area, type and ages. The MODIS albedo product from 2001 to 2007 is used to extract albedo from "pure" disturbed pixels. The changes of albedo are independently analyzed by time of year, for snowy or non-snowy conditions, and along an axes of years since disturbance, and the type of disturbance. Our initial results show an increasing trend of forest albedo in burned areas in the first several years (1-15 years) under snow-free conditions. Under snow-covered conditions, albedo of burned areas increases in the first several years (~7 years) and then becomes stable. In clear-cut regions, albedo is stable under snow-free conditions but decreases under snow-covered conditions, and returns to the pre-clear-cut value in about 23 years. Future work will focus on direct retrieval of albedo changes from the Landsat record, as well as using land surface and biogeochemical models to assess the "whole climate" impact of future land use/disturbance scenarios.

To explore the identification and influence of lofted dust on the measurements from the satellit instrument of the Stratospheric Aerosol and Gas Experiment (SAGE ) II, the probability density functions (PDFs) of the temperature associated with SAGE II 1.02 micron extinction coefficients over desert regions, including the Central Asian Deserts, Taklimakan Desert, and Gobi Desert, are compared with those outside desert regions at similar latitudes on a seasonal basis. This PDF analysis has been applied to the SAGE II cloud as well as aerosol data obtained by using a two-wavelength cloud-aerosol separation method. The results show basically a year round single mode of the PDF associated with cloud as weel as the background aerosol outside the desert regions. Over the desert regions, the analysis shows the seasonally upward spread of desert dust as the occurrence of a higher temperature mode of the PDF, in addition to the PDF for cloud and bckground aerosol, leading to a bimodal PDF distribution. Interestingly, no lofted dust is found over desert region in the upper troposphere in winter. The present results demonstrated the feasibility of detecting the lofted dust from the desert during the non-winter seasons by searching the higher temperature mode in the bimodal PDF. The influence of seasonal large-scale circulation on the background aerosol, cloud and lofted dust is also discussed.

Since ozone in this region is an important greenhouse gas, it is important that the mean and variability of the ozone distribution are realistically represented in chemistry climate models (CCMs). The High Resolution Dynamic Limb Sounder (HIRDLS), one of the instruments on NASA's Aura satellite, measures profiles of temperature and ozone with about 1 km vertical resolution. Profiles at middle latitudes are separated by less than a degree in latitude. HIRDLS commonly observes layered structures in the lower stratosphere that sometimes persist for a week or more. These layered structures are produced by horizontal transport that is sometimes reversible. The evolution of these layers also gives evidence of mixing. In other regions, HIRDLS profiles show ozone enhancement (i.e ozone greater than the temporal mean) for a 3-4 km vertical range. Separate approaches are used to quantify the importance of these processes to variability in the lower stratosphere. The structures with broad vertical range are identified using the covariance between levels. The frequency of vertical structures is computed over the winter and spring seasons, and results are compared with a similar analysis applied to output from simulations using the NASA Goddard CCM. The contributions of the layered structures to variability and the importance of mixing are examined by computing the distributions of ozone values on potential temperature surfaces for specified intervals of potential vorticity. Ozone is often correlated with potential vorticity, and the aim of this analysis is to explore the mixing processes that are observed by HIRDLS to understand their importance to the breakdown in the pv-ozone correlation. The behavior of the pv-ozone relationship as observed by HIRDLS can be contrasted with that derived from a parallel analysis of the output of the CCM.

In both rural and very polluted situations, we find that a simple "contour graph" parameterization of the local principal ozone production rate can be estimated using only the variables [NO] and j sub(rads) [HCHO]: Po(O sub(3)) = c (j sub(rads) [HCHO]) super(a) [NO] super(b). The method immediately suggests a local interpretation for concepts of VOC limitation and NOx limitation. We believe that the product j sub(rads) [HCHO] gauges the oxidation rate of observed VOC mixtures in a way that also provides [HO sub(2)] useful for the principle ozone production rate k [HO sub(2)] [NO], Mechanisms suggest that ozone production due to RO sub(2) is proportional to the HO sub(2) process, hence we may capture all ozone chemical production. The success of the method suggests that dominant urban primary-HCHO sources may transition to secondary plume-HCHO sources, so that HCHO is never too far away from an evolving steady state with VOC reactivity. Are there other, simple, near-terminal oxidized VOC's which help gauge ozone production and aerosol particle formation? Regarding particles, we report on suggestive relationships between far-downwind (Atlantic PBL) HCHO and very fine aerosol. Since j sub(rads) [HCHO] provides a reactive-flux rate, we may understand distant-plume particle production in a more quantitative manner. Additionally, we report on a statistical search in the nearer field for relationships between glyoxals (important penultimate aromatic and isoprene reaction products) with ozone and aerosol production, looking for VOC's that might be most implicated, e.g aromatics and biogenics. Note that all three of our variables j sub(rads), [HCHO], and [NO] are relatively easily measured in widespread air pollution networks, and all are deducible form space-borne observations. Estimation of [NO] from [NO sub(2)] (the species observable from space) may require care. Wider measurement of HCHO and its reactivity should be key environmental measurements, justifying relatively greater expeditures. Fortunately, the use of the 3.58 micron microwindow for HCHO remote sensing allows more economical resolution of HCHO than other techniques.

Satellite observations of tropospheric composition provide a unique opportunity to characterize mega-city pollution. Here we focuse on the air quality over major East Asian mega-cities: Beijing, Shanghai, Hongkong, Seoul and Tokyo in 2006. We analyzed time series of tropospheric O3, CO, and NO2 over those cites from TES, SCIAMACHY, and OMI. Results from GEOS-Chem global 3-D CTM simulations and corresponding meteorological variables including temperature and precipitation are used to understand and interpret the seasonal variations of those pollutants and controlling factors such as transport. Beijing is the most polluted among the five cities where ~200 ppbv of O3 and ~400 ppbv of CO in the lower troposphere were frequent. Those mega-cities' air quality is mostly affected by industrial/urban emissions and domestic biofuel burning from China, while the contribution from natural pollution (biomass burning and terrestrial biosphere) are fairly small. The difference in seasonal trends and photochemical O3 productivity among the cities partly reflects the different photochemical environment in the different latitudes. The strong summer monsoon over Asia causes seasonal mitigation of pollutions over those mega-cities.

The lowest phyllosilicate unit is Fe/Mg- smectite that likely formed via aqueous alteration of basalt. This unit is overlain by rocks rich in hydrated silica, montmorillonite, and kaolinite that probably formed via subsequent leaching of Fe and Mg through extended aqueous events or a change in aqueous chemistry. An Fe super(2+) phase is present at the transition from Fe/Mg-smectite to Al/Si-rich material and implies active redox processes here during the Noachian period. The ferrous phase is identified by an increasing spectral slope from about 1 to 1.8 μ m that is common to a variety of ferrous minerals including clays, carbonates, sulfates, and olivine. As we do not observe direct spectral evidence of any of these minerals, we attribute the ferrous phase to a ferrous mica, which has only weak OH bands and is the most likely material interstratified with the clay units. At the CRISM scale of 18 or 36 meters/pixel this ferrous unit is mixed with the Fe/Mg-smectite below it as well as the hydrated silica unit above it. Fe super(2+)-bearing materials in terrestrial sediments are typically associated with microorganisms or changes in pH or cations, and could be explained here by hydrothermal activity. The stratigraphy of Fe/Mg-smectite overlain by a ferrous phase, hydrated silica and then Al-phyllosilicates implies a complex aqueous history. References: [1] Bishop J. L. et al.

Aerosol indirect effects are characterized by the effects of aerosol on cloud radiative properties. This being a subject of significant interest for climate change and human health effects, many computational and satellite data analysis studies have been made to understand this mechanism. However, most of the studies are made on understanding the global effects. In this work we attempt to understand the local effects by making quantitative analysis of aerosol and its indirect effects in three polluted Asian cities. We analyze aerosol optical depth (AOD) data from MODIS (Moderate Resolution Imaging Spectroradiometer) and MISR (Multiangle Imaging SpectroRadiometer), aerosol extinction optical depth, absorption optical depth, and aerosol index (AI) data from OMI (Ozone Monitoring Instrument) and compare with AOD data of AERONET (Aerosol Robotic Network) at Beijing, China; Dalanzadgad, Mongolia; and Kanpur, India. Cloud parameters from MODIS data are correlated with aerosol optical depth. Seasonal variation of aerosol optical depth and its effect on cloud radiative properties are discussed. Large differences in AOD are observed in the measurements by different instruments. The differences in the results of indirect effects indicate considerable influence of local environment.

LiDAR-only, RaDAR-only, and joint LiDAR-RaDAR linear models were developed to determine if returns from two sensors could be used to estimate pine biomass more accurately and precisely than returns from either sensor alone. The best five-variable RaDAR model explained 81.8% (R super(2)) of the stem green biomass variability, with a regression RMSE of 57.5 t/ha. The best one-variable LiDAR model explained 93.3% of the biomass variation (RMSE=33.9 t/ha). Combining the RaDAR normalized volumetric returns with the profiling LiDAR ranging measurements did little to improve the best LiDAR-only model. The best LiDAR-RaDAR model explained 93.8% of the biomass variation (RSME=32.7 t/ha). Cross-validation and training /test validation procedures demonstrated (1) that all models are unbiased and (2) the increased precision of the LiDAR-only and LiDAR-RaDAR models. The results of this investigation and a companion study indicate that there is little to be gained combining VHF-RaDAR volumetric returns and profiling LiDAR ranging measurements in pine forests; a LiDAR ranging system is sufficient for accurate, precise biomass estimation.

However, the processes of infiltration, runoff, and evapotranspiration in the vadose zone of the soil are not easy to quantify or predict because of the difficulty in accurately representing soil texture and hydraulic properties in land surface models. This study approaches the problem of parameterizing soil properties from a unique perspective based on components originally developed for operational estimation of soil moisture for mobility assessments. Estimates of near-surface soil moisture derived from passive (L-band) microwave remote sensing were acquired on six dates during the Monsoon '90 experiment in southeastern Arizona, and used to calibrate hydraulic properties in an offline land surface model and infer information on the soil conditions of the region. Specifically, a robust parameter estimation tool (PEST) was used to calibrate the Noah land surface model and run at very high spatial resolution across the Walnut Gulch Experimental Watershed. Errors in simulated versus observed soil moisture were minimized by adjusting the soil texture, which in turn controls the hydraulic properties through the use of pedotransfer functions. By estimating within a continuous range of widely applicable soil properties such as sand, silt, and clay percentages rather than applying rigid soil texture classes, lookup tables, or large parameter sets as in previous studies, the physical accuracy and consistency of the resulting soils could then be assessed. In addition, the sensitivity of this calibration method to the number and timing of microwave retrievals is determined in relation to the temporal patterns in precipitation and soil drying. The resultant soil properties were applied to an extended time period demonstrating the improvement in simulated soil moisture over that using default or county-level soil parameters. The methodology is also applied to an independent case at Walnut Gulch using a new soil moisture product from active (C-band) radar imagery with much lower spatial and temporal resolution. Overall, results demonstrate the potential to gain physically meaningful soil information using simple parameter estimation with few but appropriately timed remote sensing retrievals.

The value for (super 186) Os/ (super 188) Os is within uncertainty of the present-day value for the primitive upper mantle of 0.1198398+ or -16. These Os isotope systematics are best explained by ancient recycled crust or melt enrichment in the mantle source region. If so, then the coupled enrichments displayed in (super 186) Os/ (super 188) Os and (super 187) Os/ (super 188) Os from lavas of other plume systems must result from an independent process, the most viable candidate at present remains core-mantle interaction. While some plumes with high (super 3) He/ (super 4) He, such as Hawaii, appear to have been subjected to detectable addition of Os (and possibly He) from the outer core, others such as Iceland do not. A positive correlation between (super 187) Os/ (super 188) Os and (super 3) He/ (super 4) He from 9.6 to 19 Ra in Iceland picrites is best modeled as mixtures of 1 Ga or older ancient recycled crust mixed with primitive mantle or incompletely degassed depleted mantle isolated since 1-1.5 Ga, which preserves the high (super 3) He/ (super 4) He of the depleted mantle at the time. These mixtures create a hybrid source region that subsequently mixes with the present-day convecting MORB mantle during ascent and melting. This multistage mixing scenario requires convective isolation in the deep mantle for hundreds of million years or more to maintain these compositionally distinct hybrid sources. The (super 3) He/ (super 4) He of lavas derived from the Iceland plume changed over time, from a maximum of 50 Ra at 60 Ma, to approximately 25-27 Ra at present. The changes are coupled with distinct compositional gaps between the different aged lavas when (super 3) He/ (super 4) He is plotted versus various geochemical parameters such as (super 143) Nd/ (super 144) Nd and La/Sm. These relationships can be interpreted as an increase in the proportion of ancient recycled crust in the upwelling plume over this time period. The positive correlation between (super 187) Os/ (super 188) Os and (super 3) He/ (super 4) He demonstrates that the Iceland lava He isotopic compositions do not result from simple melt depletion histories and consequent removal of U and Th in their mantle sources. Instead their He isotopic compositions reflect mixtures of heterogeneous materials formed at different times with different U and Th concentrations.

Bulk chemical analyses (including organic carbon and mean total H (sub 2) O content) are consistent with a CR classification. Additionally, oxygen isotope analysis on a bulk sample indicates that Shisr 033 is of type CR2. Amino acid analysis using liquid chromatography with UV fluorescence detection (HPLC-FD) and liquid chromatography-time of flight-mass spectrometry (LC-ToF-MS) show that the absolute and the relative amino acid content of Shisr 033 is distinct from other carbonaceous chondrites. Oxygen isotope analysis of a phyllosilicate-rich dark inclusion shows that this inclusion is closer to CV3 or CO3 chondrites. The effects of terrestrial weathering in Shisr 033 are evident from the dark inclusion carbon isotopic data, bulk chemistry (through the elevated concentrations of Sr and Ba), and amino acid data, which suggests extensive amino acid contamination of the meteorite from the fall site soil. Nevertheless, Shisr 033 contains a small fraction of indigenous components, as indicated by the presence of the extraterrestrial amino acid alpha -aminoisobutyric acid (AIB) that was not detected in the Shisr soils. Finally, the terrestrial age of Shisr 033 was determined and is discussed in the context of high levels of contamination.

In perennially dry firn this relationship is well characterized by a timescale, referred to as the extinction-diffusion time, which is the ratio of the microwave extinction length squared to the firn thermal diffusivity. The extinction-diffusion time is calculated over Antarctica from 1982 to 1999 by comparing thermal infrared observations of physical surface temperature from the advanced very high resolution radiometer (AVHRR) with passive microwave brightness temperatures measured by the scanning multichannel microwave radiometer (SMMR) and Special Senor Microwave Imager (SSM/I). Independent estimates of accumulation rate are derived both from ice cores and from spatially extensive ground and airborne radar echo sounding lines. (mod. journ. abst.)

Healthy river conditions through sufficient flows and optimal temperatures are of paramount importance for the survival of Pacific salmon, which migrate upriver toward the headwaters to spawn near the end of their lives. Trends have been detected which indicate that the annual flow and summer temperature have been increasing since the middle of the last century. In this study we examine the observed trend in summer temperature of the Fraser River and compare it with temperatures calculated as part of a global climate model (GCM) simulation in which atmospheric greenhouse gases are increasing. We then use the GCM to consider how these trends might continue through the present century. Both the observations and model indicate that during the last half of the 20th century, the summer temperature near the river mouth has been increasing at a rate of approximately 0.12 degrees C per decade in August. In this study we use an online method in which river temperatures are calculated directly as part of a GCM simulation and project how summer temperature near the mouth of the Fraser River might change by the end of the present century. The results indicate that between 2000 and 2100 river temperatures will increase in all summer months with a maximum increase of 0.14 degrees C per decade in August. This result is consistent with an offline modeling study by [Morrison, J., Quick, M.C., Goreman, M.G.G. 2002. Climate change in the Fraser River watershed: flow and temperature projections. Journal of Hydrology, 263, 230-244] in which they used output from two GCMS to drive a hydrologic model and predict future changes in river temperature and supports their contention that the timing and magnitude of the increase could be crucial for salmon migration. Future work can extend this analysis to other river systems in an effort to project the potential effects of climate change on the behavior of the world's large river basins, as well as identify the potential biological effects that may accompany these changes.

To understand the history of water on Mars, we take a close look at key locations with the High-Resolution Imaging Science Experiment on board the Mars Reconnaissance Orbiter, reaching fine spatial scales of 25 to 32 centimeters per pixel. Boulders ranging up to approximately 2 meters in diameter are ubiquitous in the middle to high latitudes, which include deposits previously interpreted as fine-grained ocean sediments or dusty snow. Bright gully deposits identify six locations with very recent activity, but these lie on steep (20 degrees to 35 degrees ) slopes where dry mass wasting could occur. Thus, we cannot confirm the reality of ancient oceans or water in active gullies but do see evidence of fluvial modification of geologically recent mid-latitude gullies and equatorial impact craters.

Bias estimation may therefore be needed for data assimilation. Here, in situ soil moisture profile observations in a small agricultural field were merged with Community Land Model (CLM2.0) simulations using different algorithms for state and forecast bias estimation with and without bias correction feedback. Simple state updating with the conventional ensemble Kalman filter (EnKF) allows for some implicit forecast bias correction. It is possible to estimate the soil moisture bias explicitly and derive superior soil moisture estimates with a generalized EnKF that uses a simple persistence model for the bias and assumes that the a priori bias error covariance is proportional to the a priori state error covariance. For the case of bi-weekly assimilation of the entire profile of soil moisture observations, bias estimation and correction typically reduces the RMSE in soil moisture (over the standard EnKF without bias correction) by around 60 percent. However, under the above assumptions, significant improvements are limited to state variables for which observations are available. Therefore, it is crucial to measure the state variables of interest. The best variant for state and bias estimation depends on the nature of the model bias and the output of interest to the user. In a model that is only biased for soil moisture, large and frequent increments for soil moisture updating may be required, which in turn may negatively impact the water balance and output fluxes. It is then better to post-process the soil moisture with the bias analysis without updating the model state. Copyright 2007 by the American Geophysical Union.

The measured limb radiances are inverted to yield vertical profiles of the volume emission rate of energy from the O sub(2) molecule. From these emission rates we subsequently derive the mesospheric ozone concentrations using a nonlocal thermodynamic equilibrium (non- LTE) radiative and kinetic model. Rates of energy deposition due to absorption of ultraviolet radiation in the Hartley band of ozone are also derived, independent of knowledge of the ozone abundance and solar irradiances. Atomic oxygen concentrations are obtained from the ozone abundance using photochemical steady state assumptions. Rates of energy deposition due to exothermic chemical reactions are also derived. The data products illustrated here are from a test day (4 July 2002) of SABER Version 1.07 data which are now becoming publicly available.

Samples were collected from facilities at the Jet Propulsion Laboratory (JPL), Kennedy Space Flight Center (KSC), and Johnson Space Center (JSC). Nine clone libraries representing different surfaces within the spacecraft facilities and three libraries from the surrounding air were created. Despite the highly desiccated, nutrient-bare conditions within these clean rooms, a broad diversity of bacteria was detected, covering all the main bacterial phyla. Furthermore, the bacterial communities were significantly different from each other, revealing only a small subset of microorganisms common to all locations (e.g. Sphingomonas, Staphylococcus). Samples from JSC assembly room surfaces showed the greatest diversity of bacteria, particularly within the Alpha- and Gammaproteobacteria and Actinobacteria. The bacterial community structure of KSC assembly surfaces revealed a high presence of proteobacterial groups, whereas the surface samples collected from the JPL assembly facility showed a predominance of Firmicutes. Our study presents the first extended molecular survey and comparison of NASA spacecraft assembly facilities, and provides new insights into the bacterial diversity of clean room environments .

These effects may result from increased neuromuscular activation during WBV; however, previous studies of neuromuscular responses during WBV have not accounted for motion artifact Methods: Sixteen healthy adults performed a series of static and dynamic unloaded squats with and without two different directions of WBV (rotational vibration, RV; and vertical vibration, VV; 30 Hz; 4 mm sub(p)_ sub(p)). Activation of unilateral vastus lateralis, biceps femoris, gastrocnemius, and tibialis anterior was recorded using EMG. During RV and VV, increases in EMG relative to baseline were compared over a range of knee angles, contraction types (concentric, eccentric, isometric), and squatting types (static, dynamic). Results: After removing large, vibration-induced artifacts from EMG data using digital band-stop filters, neuromuscular activation of all four muscles increased significantly (P less than or equal to 0.05) during RV and VV. Average responses of the extensors were significantly greater during RV than VV, whereas responses of the tibialis anterior were significantly greater during VV than RV. For all four muscles, responses during static squatting were greater than or equal to responses during dynamic squatting, whereas responses during eccentric contractions were equal to or smaller than responses during concentric and isometric contractions. Neuromuscular responses of vastus lateralis, gastrocnemius, and tibialis anterior were affected by knee angle, with greatest responses at small knee angles. Conclusions: Motion artifacts should be removed from EMG data collected during WBV. We propose that neuromuscular responses during WBV may be modulated by leg muscle cocontraction as a postural control strategy and/or muscle tuning by the CNS intended to minimize soft-tissue vibration.

By when and by how much are impacts reduced? Where does it matter most? We investigated these questions within the new A2 emission scenario, recently developed at the International Institute of Applied Systems Analysis with revised population and gross domestic product projections. Coupling an agro-ecological model to a global food trade model, two distinct sets of climate simulations were analyzed: 1) A non-mitigated scenario, with atmospheric CO sub(2) concentrations over 800 ppm by 2100; and 2) A mitigation scenario, with CO sub(2) concentrations stabilized at 550 ppm by 2100. Impacts of climate change on crop yield were evaluated for the period 1990-2080, then used as input for economic analyses. Key trends were computed over the 21st century for food demand, production and trade, focusing on potential monetary (aggregate value added) and human (risk of hunger) impacts. The results from this study suggested that mitigation could positively impact agriculture. With mitigation, global costs of climate change, though relatively small in absolute amounts, were reduced by 75-100%; and the number of additional people at risk of malnutrition was reduced by 80-95%. Significant geographic and temporal differences were found. Regional effects often diverged from global net results, with some regions worse off under mitigation compared to the unmitigated case.

This is particularly true for Asia, where some of the Earth's oldest and driest deserts occur. Using methods derived from plant landscape ecology, we measured the abundance and spatial distribution of cyanobacterial colonization on quartz stony pavement across environmental gradients of rainfall and temperature in the isolated Taklimakan and Qaidam Basin deserts of western China. Colonization within available habitat ranged from 0.37 plus or minus 0.16% to 12.6 plus or minus 1.8%, with cold dry desert sites exhibiting the lowest abundance. Variation between sites was most strongly correlated with moisture-related variables and was independent of substrate availability. Cyanobacterial communities were spatially aggregated at multiple scales in patterns distinct from the underlying rock pattern. Site-level differences in cyanobacterial spatial pattern (e.g. mean inter-patch distance) were linked with rainfall, whereas patchiness within sites was correlated with local geology (greater colonization frequency of large rocks) and biology (dispersal during rainfall). We suggest that cyanobacterial patchiness may also in part be self-organized - that is, an outcome of soil water-biological feedbacks. We propose that landscape ecology concepts and models linking desert vegetation, biological feedbacks and ecohydrological processes are applicable to microbial communities.

Using a geographic information system, available habitat was partitioned into concentric bands at five, ten, and 15 km radius from nesting colonies to assess the relative effects of habitat composition and distance on habitat selection. Snowy Egrets were more likely than Great Egrets to depart colonies and travel to foraging sites in groups, but both species usually arrived at sites that were occupied by other wading birds. Mean flight distances were 6.2 km (SE = 0.4, N = 28, range 1.8-10.7 km) for Great Egrets and 4.7 km (SE = 0.48, N = 31, range 0.7-12.5 km) for Snowy Egrets. At the broadest spatial scale both species used impounded (mostly salt marsh) and estuarine edge habitat more than expected based on availability while avoiding unimpounded (mostly fresh water wetland) habitat. At more local scales habitat use matched availability. Interpretation of habitat preference differed with the types of habitat that were included and the maximum distance that habitat was considered available. These results illustrate that caution is needed when interpreting the results of habitat preference studies when individuals are constrained in their choice of habitats, such as for central place foragers.

We consider the photothermal escape flows known as the polar wind or refilling flows, the enhanced mass flux escape flows that result from localized solar wind energy dissipation in the auroral zones, and the resultant enhanced neutral atom escape flows. We term these latter two escape flows the "auroral wind." We review observations and theories of the heating and acceleration of auroral winds, including energy inputs from precipitating particles, electromagnetic energy flux at magnetohydrodynamic and plasma wave frequencies, and acceleration by parallel electric fields and by convection pickup processes also known as "centrifugal acceleration." We consider also the global circulation of ionospheric plasmas within the magnetosphere, their participation in magnetospheric disturbances as absorbers of momentum and energy, and their ultimate loss from the magnetosphere into the downstream solar wind, loading reconnection processes that occur at high altitudes near the magnetospheric boundaries. We consider the role of planetary magnetization and the accumulating evidence of stellar ablation of extrasolar planetary atmospheres. Finally, we suggest and discuss future needs for both the theory and observation of the planetary ionospheres and their role in solar wind interactions, to achieve the generality required for a predictive science of the coupling of stellar and planetary atmospheres over the full range of possible conditions.

AN - 36340917; 12892 AB - PURPOSE: The adoption of conceptual schemes and schematic alternative approaches is proposed in this programmatic EIS on the Constellation Program, which aims to allow humans to travel to the Moon, Mars, and beyond. In 2004, President George W. Bush announced a new exploration initiative, the Vision For Space Exploration Initiative, to return humans to the Moon by 2020 in preparation for the exploration of Mars and points beyond. As a first step toward developing vehicles to achieve the goals of this initiative, the President directed the National Aeronautics and Space Administration (NASA) to develop and fly a new Crew Exploration Vehicle (CEV, since named Orion) by 2014. The Orion spacecraft would e capable of transporting humans to the International Space Station (ISS), the Moon, and would be used on future missions to Mars and beyond. The associated program would complete the assessment of top-level CEV requirements and plans to enable CEVs to provide crew transport to the ISS and to accelerate the development of the CEV design and crew launch systems to reduce the gap between Space Shuttle retirement and CEV operational capability; provide definitions of top-level requirements and configurations for crew and cargo launch systems to support the lunar and Martian exploration programs; develop a reference lunar exploration architecture concept to support sustained human robotic lunar exploration operations; and identify key technologies required to enable and significantly enhance these reference exploration systems and reprioritize near- and long-term technology requirements. Constellation Program components would be implemented at the Johnson Space Center, Marshall Space Flight Center, Michoud Assembly Facility, and Kennedy Space Center and in as yet undetermined research and development facilities. Areas potentially affected by program activities include Brevard and Volusia counties, Florida; Hancock County, Mississippi; Orleans Parish, Louisiana; Harris County, Texas; Madison County, Alabama; Cuyahoga and Erie counties, Ohio; Hampton, Virginia; Santa Clara County, California; Dona Ana and Otero counties, New Mexico; and Box Elder and Davis counties, Utah. In addition to the proposed action this draft EIS addresses a No Action Alternative. POSITIVE IMPACTS: The proposed program would implement a sustained and affordable human and robotic program to explore the Solar System and beyond; extend human presence across the Solar System, starting with a return of humans to the Moon by 2020 in preparation for human exploration of mars and other Solar System destinations; develop innovative technologies, knowledge, and infrastructure both to explore and to support decisions about the designations for human exploration; and promote international and commercial participation in this new space exploration program. NEGATIVE IMPACTS: Potential building modifications and/or new construction at research and development facilities would result in impacts typical of such construction projects, largely loss of permeable soil and vegetation. Construction activities would be expected at Michoud Assembly Facility, Kennedy Space Center, and Ames Research Center. New hazardous materials processing facilities would be placed at Kennedy Space Center. Orion thermal protection system flight tests would result in the usual impacts of launching spacecraft.
