MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

This proposal is for the development of an innovative compact, high power, and extremely reliable 1.26 micron Ho-doped single frequency fiber laser. The proposed single frequency fiber laser consists of Raman pump laser and single frequency 1.26-micron fiber laser, which will be constructed by using Ho3+-doped fluoride glass fiber. A Raman fiber laser is used as a resonant pump laser source for Ho3+-doped fiber laser. High gain per unit length can be achieved in Ho3+-doped fluoride glass fiber due to the strong resonant pump. This type of fiber based seed laser is needed for remote sensing of O and O -N for measuring atmospheric pressure. The single frequency 1.26-micron fiber laser with high-speed frequency modulation capability and electronic control, which will be developed in Phase II as part of the seed laser, can be used to build coherent laser radar to perform instant measurement.

Maines coastal islands and beaches provide important nesting habitat for piping plover Charadrius melodus, least tern Sterna antillarum, common tern Sterna hirundo, Arctic tern Sterna paradisaea, Atlantic puffin Fratercula arctica, black guillemot Cepphus grylle, and common eider Somateria mollissima. These species are managed and regularly monitored by the U.S. Fish and Wildlife Service USFWS, National Audubon Society NAS, Maine Department of Inland Fisheries and Wildlife MDIFW, BioDiversity Research Institute BRI, Maine Audubon Society MAS and other partners in the Gulf of Maine Seabird Working Group. Each nesting season, these organizations collect nonviable and abandoned eggs when available. Relatively few contaminant investigations have been performed with birds at coastal sites in Maine. In particular, little is known about mercury exposure in bird species using coastal beaches and islands. To address this data gap, we summarize mercury exposure in nonviable and abandoned bird eggs collected between 1993 and 2004 from ten locations along the Maine coast. Eightytwo eggs from seven species were collected. Fifty eggs were analyzed individually for mercury and 32 eggs were formed into six speciesspecific composites prior to analysis.

The U.S. Geological Survey Upper Midwest Environmental Sciences Center (UMESC) has produced a vegetation spatial database coverage (vegetation map) for the Effigy Mounds National Monument (EFMO) Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program (VMP). The vegetation map shows the locations of plant communities (associations) at EFMO and immediate surroundings. To develop the plant community classification, vegetation samples were collected and analyzed, identifying 15 plant communities of the National Vegetation Classification System (NVCS). (2 more plant communities, however, were identified using accuracy assessment field data, making 17 total plant communities for the EFMO vegetation mapping project.) Ecologists and botanists from UMESC, under the direction of NatureServe, collected 63 vegetation plot samples, 55 collected in 2001 and 8 more in 2002. The UMESC and NatureServe performed ordination analysis to the sampling data. Plant communities of EFMO are defined and described at the local and global scale. (Local descriptions were written for only those 15 associations supported with plot data.) The UMESC has generated a spatial database showing the locations of all 63 vegetation plot samples. Selected field data items extracted from the project's PLOTS database are also included.

Summary
Description
With increasing population growth and land-use change, urban communities in the desert southwest are progressively looking to remote basins to supplement existing water supplies. Recent applications for groundwater appropriations from Dixie Valley, Nevada, a primarily undeveloped basin neighboring the Carson Desert to the east, have prompted a reevaluation of the quantity of naturally discharging groundwater. The objective of this study was to develop a new, independent estimate of groundwater discharge by evapotranspiration (ET) from Dixie Valley using a combination of eddy-covariance evapotranspiration measurements and multispectral satellite imagery. Mean annual groundwater ET (ETg) was estimated during October 2009-2011 at four eddy covariance sites. Two sites were located in phreatophytic shrubland dominated by greasewood and two were located on a playa. Estimates were scaled to the basin level by combining remotely sensed imagery with field reconnaissance and site-scale ETg estimates. The Enhanced Vegetation Index (EVI) was calculated for 10 Landsat 5 Thematic mapper scenes and combined with brightness temperature in an effort to reduce confounding (high) EVI values resulting from forbes and cheat grass in sparsely vegetated areas, and biological soil crusts from bare soil to densely vegetated areas. The resulting EVI/TB images represented by this dataset were used to calculate ET units and scale actual and potential ETg to the basin level.
Metabolic Heat Regenerated Temperature Swing Adsorption for CO2, Thermal and Humidity Control Project

Summary
Description
Metabolic heat regenerated Temperature Swing Adsorption (MTSA) technology is proposed for a Portable Life Support System to remove and reject heat and carbon dioxide (CO2) regardless of the environment (lunar or Mars, vacuum or CO2), as well as to help control humidity in the ventilation loop. The basic principal is removal of metabolically-produced CO2 by an adsorbent with regeneration using a temperature swing. The lower temperature is achieved via expansion of liquid CO2 (LCO2). The higher temperature is achieved with metabolic heat from the moist ventilation loop gas through a condensing ice heat exchanger. The condensed water is saved and recycled at the habitat. Both the LCO2 exhaust and the metabolically-produced CO2 are rejected to the surrounding environment. The effective temperature swing is between the CO2 sublimation temperature (~195 K) and the ventilation loop gas temperature (~300 K). MTSA has reasonable mass, volume and power with minimal impact on infrastructure and operations. The basic principles of MTSA technology are well-proven, safe, do not rely on cryogenics, do not consume water but conserve it, are regenerable and will not compromise scientific investigations by sublimating water for heat rejection onto the premises. An added benefit of MTSA technology is that the LCO2 coolant can be produced and stored on the surface of Mars, saving launch costs and providing easy emergency access and replenishment. As Paragon has demonstrated adsorbent and LCO2 cooling performance relevant to MTSA operating conditions, Phase 1 will emphasize understanding the condensing ice heat exchanger design through analytical formulations and validation through testing. Paragon's unique experience will ensure that this Phase 1 effort will be successful, resulting in a strong Phase 2 MTSA development plan to design, build and test in a relevant environment a full-scale MTSA subsystem prototype.

This digital-map data set consists of a grid of generalized skew coefficients of logarithms of annual maximum streamflow for Oklahoma streams less than or equal to 2,510 square miles in drainage area. This grid of skew coefficients is taken from figure 11 of the Tortorelli and Bergman, 1985 report, "Techniques for estimating flood peak discharges for unregulated streams and streams regulated by small floodwater retarding structures in Oklahoma," U.S. Geological Survey Water-Resources Investigations Report 84-4358. The skew coefficients were used to develop peak-flow regression equations in the Tortorelli, 1997 report, "Techniques for estimating peak-streamflow frequency for unregulated streams and streams regulated by small floodwater retarding structures in Oklahoma," U.S. Geological Survey Water-Resources Investigations Report 97-4202. Only skew coefficient values within Oklahoma are intended for use with the regression equations. To save disk space, the skew coefficient values have been multiplied by 100 and rounded to integers with two significant digits.

This data set consists of measurements of GPS signals reflected from the Earth's surface and collected on an airborne platform. A modified GPS Delay Mapping Receiver (DMR) tracks and measures the direct, line-of-sight, right hand circulary polarized (RHCP) signal of a GPS satellite. It also simultaneously measures the delayed, Earth-reflected, near-specular, LHCP GPS signal. These measurements are a form of bistatic radar. The measurements can be used to estimate the surface scattering coefficient and path delays between the direct and reflected GPS signals. Over land, scattering coefficients can be used to estimate changes in surface soil moisture. Over water surfaces, the reflected pulses can be used to sense roughness and derive wind speeds. The bistatic range measurements can also be used to estimate the receiver height above the surface in a form of aircraft altimetry. Data were collected throughout each Meso-cell Study Area (MSA) within the Cold Land Processes Field Experiment (CLPX) Small Regional Study Area (SRSA, 39.5 N-41 N, 105 W-107.5 W). Spatial resolution of these data is variable depending on airborne height and scattering regime (specular or rough). Data were collected 19 and 21 February 2002, and 22-24 February and 25, 30, 31 March 2003. Data are available via FTP.
