Visible and infrared radiances are measured in two spectral channels by the Visible and Infrared Spin-Scan Radiometer (VISSR) on the Synchronous Meteorological Satellite (SMS) series and the Geostationary Operational Environmental Satellite (GOES) series. Eight visible detectors simultaneously scan the 0.55 to 0.75 micrometer region, while two infrared (IR) detectors scan the 10.5 to 12.6 micrometer regions as the VISSR views the Earth. These channels are used for day/night cloud mapping, surface temperature determination, and weather forecasting. The cloud motion vectors are derived from successive pairs of VISSR (Visible-IRSpin Scan Radiometer) images by both manual and automated techniques. This process is performed twice daily with the VISSR data from each of two GOES satellites. Each set of cloud motion vector information describes one measurement, and includes; a year-month-day-hour time tag, latitude and longitude, pressure altitude, measured or computed cloud motion (wind) speed and direction, an automated/manual indicator, and quality information.

Processing Steps and Data Sets. The radiance values detected by the VISSR are merged with a scan line identifier, sun pulse data (calibration), and synchronization data for each scan line. All data are immediately transmitted to the Command and Data Acquisition (CDA) station at Wallops Island, Virginia. There is no buffering or on-board recording. At the CDA station, the data are adjusted for bias and gain, calibrated, gridded and registered by the GOES Processor/Distribution Unit (P/DU). These data, termed Stretched VAS (SVAS), are then retransmitted to the satellite at 14 Mbps and relayed to remote receiving stations at Goddard Space Flight Center (GSFC) and the University of Wisconsin (UW).
