Summary
Description
This tabular data set represents the mean annual natural groundwater recharge, in millimeters, compiled for every MRB_E2RF1catchment of selected Major River Basins (MRBs, Crawford and others, 2006). The source data set is Estimated Mean Annual Natural Ground-Water Recharge in the Conterminous United States (Wolock, 2003). The MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental Protection Agency's (USEPA) ERF1_2 and include enhancements to support national and regional-scale surface-water quality modeling (Nolan and others, 2002; Brakebill and others, 2011). Data were compiled for every MRB_E2RF1 catchment for the conterminous United States covering New England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee (MRB2), the Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the Missouri (MRB4), the Lower Mississippi, Arkansas-White-Red, and Texas-Gulf (MRB5), the Rio Grande, Colorado, and the Great basin (MRB6), the Pacific Northwest (MRB7) river basins, and California (MRB8).

The SeaWiFS instrument was launched by Orbital Sciences Corporation on the OrbView-2 (a.k.a. SeaStar) satellite in August 1997, and collected data from September 1997 until the end of mission in December 2010. SeaWiFS had 8 spectral bands from 412 to 865 nm. It collected global data at 4 km resolution, and local data (limited onboard storage and direct broadcast) at 1 km. The mission and sensor were optimized for ocean color measurements, with a local noon (descending) equator crossing time orbit, fore-and-aft tilt capability, full dynamic range, and low polarization sensitivity.

The SORCE SOLSTICE Far-UV Solar Spectral Irradiance (SSI) data product SOR3SOLFUVD is constructed using measurements from the SOLSTICE FUV instrument, which are combined into merged daily solar spectra over the spectral range from 115 to 180 nm at a spectral resolution of 1 nm. Irradiances are reported at a mean solar distance of 1 AU and zero relative line-of-sight velocity with respect to the Sun. The SOLSTICE absolute uncertainty better than 5%. All of the SOR3SOLFUVD data are arranged in a single file in a tabular ASCII text file which can be easily read into a spreadsheet application. The columns contain the date, Julian day, minimum wavelength, maximum wavelength, instrument mode, data version number, irradiance value, irradiance uncertainty, and data quality. The rows are arranged with data at each wavelength over the full SOLSTICE FUV wavelength range, repeating for each day for the length of the measurement period.

Summary
Description
Instruments flown on board NASA missions often do not measure quantities of interest to scientists directly, but rather observable quantities. In addition, instruments often introduce artifacts into the data and techniques are needed to remove them. In both cases, scientifically relevant information can be inferred by simulating a parameterized model and adjusting the parameters to best match observed data. This minimization process of "fitting" a model to data is computationally demanding, since it requires evaluating the often complex models many times and minimizing a function of many variables. Fast, more efficient fitting techniques are therefore required in order to fully harvest the scientific output from NASA missions. In this project, we will develop a fast, general-purpose parameter fitting software tool suite taking advantage of inexpensive, high-performance graphics processing units (GPUs). The goal of Phase I of this project is to demonstrate the feasibility of model fitting on GPUs. We will therefore prototype forward models, relevant mathematical operators and the actual parameter adjustment algorithm on GPUs and compare their performance to a pure CPU implementation. We will particularly focus on ease of use for the scientist to migrate their applications to this infrastructure. During Phase I, the TRL will increase from 3 to 4. In the Phase II, we will then harden the prototypes developed in Phase I and provide alternative modeling algorithms to support a broader range of applications. In addition, we will work with scientists from various NASA missions, including the Stratospheric Aerosol and Gas Experiment (SAGE) III mission and the Solar Dynamics Observatory (SDO) to accelerate their modeling needs. In addition to NASA missions, other federal or commercial applications requiring to adjust model parameters to fit large sets of observed data will benefit from this project.

Summary
Description
The proposed innovation is a simple, robust, sensor array for the detection of laminar/turbulent transition location, areas of flowfield separation, and shock wave locations. The system can be used in both ground and flight test facilities. The proposed system uses a very robust and proven sensor technology combined with a novel mounting and manufacturing technique. The sensor array is reusable and can be produced in a configuration that requires no external power, acquisition or viewing, for flight test applications. The system combines an array of small, surface flush, sensors embedded in an extremely thin, flexible polyimide strip. The system operates by sensing changes in local heat transfer within the boundary-layer. Variations in heat transfer coefficients due to the state of the boundary layer (laminar, transitional, turbulent, separated regions) produce changes in the sensor output. Other flowfield features where heat transfer is affected will also be discernable, such as shock waves. The flush mounted sensors, embedded in a smooth, thin polyimide sheet, conform to the local surface contour and produce minimal aerodynamic interference, allowing non-intrusive measurements. The system will be quantitatively accurate across the low-speed through supersonic flow regime. After testing, the system can be quickly removed and reused. Compared to current systems designed for similar measurements, the proposed system promises to provide a significantly more robust and efficient system in a relatively simple, cost effective package.

The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).

<p>CA-TPS is leveraging earlier investments made by ARMD&rsquo;s Hypersonic and HEOMD&rsquo;s ETDD program that matured the concept from TRL 1 to 2.CA-TPS starts with thick, carbonized rayon felt and the flexible felt is converted to ablative TPS via low density phenolic resin infusion similar to the PICA process.&nbsp; The resulting conformal TPS molded to the required shape prior to resin infusion can then be machined and bonded to the carrier structure.&nbsp; The ease of machining holes to accommodate protrusion on the heat shield or back shell is an attractive feature.&nbsp; The material can be machined with exceptional tolerance and compliance which allows TPS integration with extremely simple seams to form a robust system. The design should result in much larger molded TPS panels that can be directly bonded to most carrier structures and allow for a simplified design of seams between gore panels.&nbsp; This will eliminate the need for gap filler design and strain isolation pads, and should accommodate a wider range of allowable carrier structure imperfections when compared to a rigid material such as PICA.</p>

Summary
Description
Rates of long-term and short-term shoreline change were generated in a GIS with the Digital Shoreline Analysis System (DSAS) version 2.0, an ArcView extension developed by the U.S. Geological Survey (USGS) in cooperation with TPMC Environmental Services. The extension is designed to efficiently lead a user through the major steps of shoreline change analysis. This extension to ArcView contains three main components that define a baseline, generate orthogonal transects at a user-defined separation along the coast, and calculate rates of change (linear regression, endpoint rate, average of rates, average of endpoints, jackknife).
