Visible and Infrared Spin-Scan Radiometer (VISSR)

NSSDCA ID: 1981-076A-01

Mission Name: GMS 2
Principal Investigator:


The Visible and Infrared Spin-Scan Radiometer (VISSR) was similar to VISSR experiments on other GARP (Global Atmospheric Research Program) satellites such as GOES 1 and GMS. The objectives were to make observations of the earth cloud cover location, land surface temperature, sea surface temperature, and cloud top temperature. It made both night IR (10.5 to 12.5 micrometers) and day IR measurements, plus visible (0.5 to 0.75 micrometer) photometric observations of the subsatellite area at 30-min intervals. The visible channel had a resolution of about 1.25 km, and the IR channel had a resolution of about 5 km at nadir. Real-time transmission was available to the data acquisition station in Japan, with additional data transmission to other meteorological users as needed. Because of optical failure since 1983, the experiment was subsequently replaced by its successor on GMS 3.
