Summary
Description
The NOAA Coastal Change Analysis Program (C-CAP) produces national standardized land cover and change products for the coastal regions of the U.S. C-CAP products inventory coastal intertidal areas, wetlands, and adjacent uplands with the goal of monitoring changes in these habitats, on a one-to-five year repeat cycle. The timeframe for this metadata is reported as 1992-2010 Era, but the actual dates of the Landsat imagery used to create the land cover may have been acquired a few years before or after each era. These maps are developed utilizing Landsat Thematic Mapper imagery, and can be used to track changes in the landscape through time. This trend information gives important feedback to managers on the success or failure of management policies and programs and aid in developing a scientific understanding of the Earth system and its response to natural and human-induced changes. This understanding allows for the prediction of impacts due to these changes and the assessment of their cumulative effects, helping coastal resource managers make more informed regional decisions. NOAA C-CAP is a contributing member to the Multi-Resolution Land Characteristics consortium and C-CAP products are included as the coastal expression of land cover within the National Land Cover Database.

NASA's new exploration initiative created immediate need for materials science and technology research to enable safe human travel and work on future lunar or Martian long-duration missions. To conduct this research, NASA must have lunar and Martian regolith simulant for materials experiments and prototype testing of transportation equipment, advanced life support systems, and in situ resource processing. This SBIR will conduct a feasibility study on a new generation of lunar and Martian simulants with improved composition and mineralogical analysis. For lunar regolith, Orbital Technologies Corporation (ORBITEC) proposes to recreate the JSC-1 material and study post-production processes to add additional percentages of glass particles to improve composition. A study to assess the feasibility of creating a lunar highlands-type simulant will also be conducted. For Martian regolith, ORBITEC will mine the raw material for the JSC Mars-1 simulant with an improved extraction process to avoid the contamination of the soil that resulted in the non-Martian magnetic component. Additional grain-size particles will also be prepared and combined with the material to improve its grain-size distribution comparison. These innovations combined with the well-documented and received original JSC-1 and Mars-1 source materials will produce simulants that will assist NASA on its future exploration quest.

This data set consists of time-series spaceborne Synthetic Aperture Radar (SAR) imagery of the three Cold Land Processes Field Experiment (CLPX) Meso-cell Study Areas (MSAs) (Fraser, Rabbit Ears, and North Park) acquired by the RADARSAT-1 Synthetic Aperture Radar (SAR). Images are derived from C-band (5.3 GHz frequency, 5.66 cm wavelength) HH-polarization Standard Beam data for multiple incidence angles. SAR data were acquired through the Alaska Satellite Facility (ASF) and post-processed at the Jet Propulsion Laboratory, California Institute of Technology, for derivation of ancillary data and assembly of the database. The data series consists of 195 individual radar scenes acquired from 17 February to 23 June 2003. Calibrated radar backscatter images are provided in binary format together with header and facility data record information for each image. Note that the Canadian Space Agency (CSA) holds copyrights over all RADARSAT-1 SAR data. NASA/NOAA-approved SAR researchers are can obtain these data directly from ASF, as per agreements between NASA/NOAA and CSA. No commercial use is allowed of the data or any products derived there from. Users of this data must submit a Research Agreement to ASF. The NASA CLPX is a multi-sensor, multi-scale experiment that focuses on extending a local-scale understanding of water fluxes, storage, and transformations to regional and global scales. Within a framework of nested study areas in the central Rocky Mountains of the western United States, ranging from 1-ha to 160,000 km2, intensive ground, airborne, and spaceborne observations are collected. Data collection focuses on two seasons: mid-winter, when conditions are generally frozen and dry, and early spring, a transitional period when both frozen and thawed, dry and wet conditions are widespread.

Summary
Description
<p>A key challenge in building a large pixel heterodyne array is efficiently and simultaneously delivering the astronomical signal and local oscillator power to each pixel and conveying the output signal from each pixel. When an array is conceived simply by tightly stacking individual receivers, which is the favored approach for high performance arrays, we soon encounter practical topological difficulties in getting the signals in and out: For CHAI there are 128 rf/local oscillator ports, IF signal outputs, mixer bias supply lines in a unit that is no bigger than 4 inches on a side. The key to our approach is to develop a highly integrated LO distribution network and build it into the array.&nbsp; Many mixer elements are thus pumped by a single source, although the resistive losses in the waveguide hampers the approach for large number of pixels. Second, we will investigate the use of the microwave ribbon cables to draw the signal from the mixer block. Although coaxial cables are used in coherent receiver systems, even small diameter semirigid cables become unwieldy when a small number is involved. The ribbon will convey the signal to the low-noise amplifier array. Several variations of the overall architecture will be evaluated: the differences between single-ended and balanced mixer approaches for a practical instrument will be investigated. While the SUPERCAM instrument has a high degree of integration with the LNA array, the LO and rf beams are still diplexed using a beam splitter approach. Most of the volume of the instrument (~1 cu meter) is simply space occupied by the quasioptical coupling scheme. A more integrated LO subsubsystem could drastically reduce the required volume. In addition, SUPERCAM uses 64 stainless steel coaxial lines to convey the signal from the front-end to the outside. This adds substantial requirements on the cryogenic system and mechanically stresses the focal plane. A ribbon cable to convey the signal from the mixer array to the LNA array and from the LNA array to the outside world is thus a much more elegant approach for implementing a high-pixel count heterodyne array.<br /><br />After the overall concept design is complete, various subsystems will be evaluated in an affordable manner. (1) For the LO distribution network, the plan is to design, fabricate and evaluate small cells of the LO distribution network operating at various frequencies to establish their feasibility. For a THz distribution network, for example, the final diode would have to be placed next to the mixer, as the high waveguide losses will not allow any significant path lengths. (2) Depending on the application the LNA array may be incorporated into the mixer array (aircraft/ground-based instrument) or be kept at a different thermal environment from the mixer (balloon or space-based instrument). These two different configurations will obviously entail different designs for the integrated heterodyne array. CHAI can potentially use either approach, and for reasons of ease of testing the latter is currently preferred. Approaches to implementing both types will be developed and described. (3) The IF is conveyed from the IF amplifiers (and possibly to them as well) by microwave flexible cables, and although this technology is not novel, their use in an astronomical heterodyne receiver has not been demonstrated. Samples would be designed, procured, and measured in the relevant environment and evaluated for loss, cross talk and survivability through multiple deep cryogenic cycles.</p>
