NSIDC-0464 Long, David and Julienne Stroeve 20110811 Enhanced-Resolution SSM/I and AMSR-E Daily Polar Brightness Temperatures Boulder, Colorado USA NSIDC: National Snow and Ice Data Center http://nsidc.org/data/nsidc-0464.html This data set contains enhanced-resolution brightness temperatures produced using the Scatterometer Image Reconstruction (SIR) algorithm developed by the Microwave Earth Remote Sensing (MERS) group at Brigham Young University (BYU). Enhanced-resolution brightness temperature images for the Arctic and Antarctic were generated using antenna temperature data from the Special Sensor Microwave/Imager (SSM/I) and the Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E) instrument. SSM/I images are available for 1995 through 2008, and AMSR-E images are available for 2002 through 2010. All available measurements for a single day are averaged into twice-daily gridded files for three different equal-area spatial coverages: Northern Hemisphere, Southern Hemisphere, and full global. The spatial resolution is 12.5 km for SSM/I channels 19 and 22 GHz, 7.5 km for 37 GHz, and 2.5 km for the 85 GHz channel. For AMSR-E, the resolution is 12.5 km for the 6, 10, 18, and 23 GHz channels; 7.5 km for the 36 GHz channel; and 2.5 km for the 89 GHz channel. Software for reading the SIR-formatted SSM/I and AMSR-E data is also available. As scatterometer and radiometer data complement each other, these enhanced-resolution radiometer data, together with SIR format scatterometer data available from BYU, will facilitate polar research that combines information from both radiometers and scatterometers. Data are stored as scaled 2-byte integers in binary arrays with a 512-byte header and are available via FTP. scientific research Long, David and Julienne Stroeve 20110811 Enhanced-Resolution SSM/I and AMSR-E Daily Polar Brightness Temperatures Boulder, Colorado USA NSIDC: National Snow and Ice Data Center http://nsidc.org/data/docs/daac/nsidc0464_enhanced_ssmi_amsre_tbs/index.html 19950101 20111001 publication date Complete Unknown -180 180 90 -90 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature NASA Global Change Master Directory (GCMD) Project Keywords EOSDIS > Earth Observing System Data Information System ESIP > Earth Science Information Partners Program NASA Global Change Master Directory (GCMD) Instrument Keywords AMSR-E > Advanced Microwave Scanning Radiometer-EOS SSM/I > Special Sensor Microwave/Imager NASA Global Change Master Directory (GCMD) Platform Keywords AQUA > Earth Observing System, AQUA DMSP 5D-2/F13 > Defense Meteorological Satellite Program-F13 ISO 19115 Topic Categories climatologyMeteorologyAtmosphere None Antarctic Arctic Daily Data EASE-Grid EOSDIS Gridded Data NSIDC DAAC Passive Microwave Polar Remote Sensing NASA Global Change Master Directory (GCMD) Location Keywords Continent > North America > Canada > Hudson Bay Geographic Region > Polar Ocean > Arctic Ocean > Baffin Bay Ocean > Arctic Ocean > Beaufort Sea Ocean > Arctic Ocean > Chukchi Sea Ocean > Atlantic Ocean > North Atlantic Ocean Ocean > Atlantic Ocean > North Atlantic Ocean > Greenland Sea Ocean > Pacific Ocean > North Pacific Ocean > Bering Sea Ocean > Southern Ocean > Amundsen Sea 6 NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature NASA Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > Spectral/Engineering > Microwave > Brightness Temperature None None NSIDC User Services National Snow and Ice Data Center mailing
