   Description: 
      Abstract:
         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.
