The instrument was carried aboard Defense Meteorological Satellite Program (DMSP) satellites F8, F10, F11, F12, F13, and F15. The Temperature Data Records (TDRs) from SSM/I contain calibrated and earth-located data prior to the (irreversible) antenna pattern correction process. These SSM/I TDRs 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 TDR dataset have been aggregated into 3-hourly files for ease of use. This SSM/I temperture data record provides valuable information on key climate parameters such as water vapor, precipitation, snow cover, sea-ice extent and land-surface temperatures. onGoing Hilawe Semunegus DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce Physical Scientist +1 828 271-4059 +1 828 271-4328 151 Patton Avenue Asheville NC 28801-5001 USA Hilawe.Semunegus@noaa.gov 8:00 am - 4:30 pm Eastern pointOfContact continual Earth Science > Spectral/Engineering > Microwave > Antenna Temperature theme Global Change Master Directory (GCMD) Science Keywords 2018 revision Version 8.6 Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA) https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords HTTPS Web Browser Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

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. The DMSP designs, builds, launches, and maintains satellites monitoring the meteorological, oceanographic, and solar-terrestrial physics environments. Equipped with a sophisticated sensor suite that can image visible and infrared cloud cover, the satellites collect specialized meteorological, oceanographic, and solar-geophysical information in all weather conditions.
