SSM/I : SPECIAL SENSOR MICROWAVE/IMAGER

NSIDC produces daily gridded brightness temperature (T_B) data from orbital (swath) data generated by the Special Sensor Microwave/Imager (SSM/I) mounted on the Defense Meteorological Satellite Program (DMSP) F8, F11, and F13 platforms. The gridded brightness temperatures are distributed in polar stereographic projection.

SSM/I is a seven-channel, four-frequency, orthogonally polarized passive microwave radiometric system. The channels are 19.3 GHz vertical and horizontal, 22.2 GHz vertical only, 37.0 GHz vertical and horizontal, and 85.5 GHz vertical and horizontal. Orbital data for each 24-hour period are mapped to respective grid cells using a simple 'drop in the bucket' sum and average method. 85.5 GHz data are gridded at a resolution of 12.5 km, with all other frequencies at a resolution of 25 km. All SSM/I T_B gridded data are stored as scaled 2-byte integers in flat binary arrays and are available via FTP.
