Special Sensor Microwave Imager/Sounder (SSMIS) Sensor Data Record (SDR) in netCDF

The Special Sensor Microwave Imager/Sounder (SSMIS) is a series of passive microwave conically scanning imagers and sounders onboard the DMSP satellites beginning with F-16. SSMIS improves upon the surface and atmospheric retrievals of the previous Special Sensor Microwave Imager (SSM/I), and upon the atmospheric temperature and water vapor sounding capabilities of both the Special Sensor Microwave Temperature Sounder (SSM/T-1) and the Special Sensor Microwave Humidity Sounder (SSM/T-2). The SSMIS imaging and sounding sensors are able to estimate atmospheric temperature, moisture, and surface parameters. This sensor data record (SDR) contains SSMIS brightness temperatures since November 2005 that have been surface tagged, calibrated, Doppler corrected, cross polarization and spill-over corrected or APC corrected according to Earth surface type, averaged along scan and along the ground track. The data have been converted to netCDF 3-hourly files.
