abstract: The Special Sensor Microwave Imager (SSM/I) is a seven-channel linearly polarized passive microwave radiometer that operates at frequencies of 19.36 (vertically and horizontally polarized), 22.235 (vertically polarized), 37.0 (vertically and horizontally polarized), and 85.5 GHz (vertically and horizontally polarized). The instrument was carried aboard Defense Meteorological Satellite Program (DMSP) satellites F8, F10, F11, F12, F13, and F15. The Sensor Data Records (SDRs) from SSM/I contain calibrated and earth-located data after antenna pattern corrections have been applied. These SSM/I SDRs in network Common Data Format (netCDF) have embedded temperature and geolocation flags as well as a climatology flag that calculates deviations from a climatological norm for each radiance footprint or z-score. The original radiance and geolocation data are not changed. Variable orbital files from the originating SDR dataset have been aggregated into 3-hourly files for ease of use.
purpose: SSM/I observations provide valuable information on key climate parameters such as water vapor, precipitation, snow cover, sea-ice extent and land-surface temperatures.

description: Collection Type: conical scan, Collection Description: The instrument sweeps a 450 cone around the satellite velocity vector so that the Earth incidence angle is always 540. Data are recorded during the 102.40 of the cone when the antenna beam intercepts the Earth's surface. The channel footprint varies with channel energy, position in the scan, along scan or along track direction and altitude of the satellite. The 85 GHz footprint is the smallest with a 13 x 15 km and the 19 GHz footprint is the largest at 43 x 69 km. Because the 85 GHz footprint is so small, it is sampled twice as often, i.e., 128 times a scan. One data cycle consists of 4 85 GHz scans and 2 scans of the 19, 22 and 37 GHz channels. The complete cycle takes 28 seconds and it must be complete to process the data.
