Definition
- The Special Sensor Microwave – Imager (SSM/I) on DMSP satellites was operated on DMSP-F08 to DMSP-F15 from 1987-2008. It was a seven channel passive microwave imaging radiometer that measured horizontal (H) and vertical polarization (V) at three frequencies (19, 37, and 85 GHz) and vertical polarization at 22 GHz. These measurements are provided at a sampling of 25 km for the 19, 37, and 22 GHz channels and a sampling of 15 km for the 85 GHz channel. CM SAF provides reprocessed SSM/I radiances and a big set of derived atmospheric variables over the ocean. OSI SAF uses the radiances for their long sea ice coverage data record.
