Definitions for "VISSR"
Abbreviation for Visible Infrared Spin-Scale Radiometer, an imaging device on the METEOSAT, GOES and GMS platforms. It is used for obtaining 2-D cloud cover pictures from a geosynchronous altitude and provides for both day and night time observations of clouds and the determination of temperatures, cloud heights, and wind fields. The instrument consists of a scanning system, a telescope, and infrared and visible sensors. It is a radiometer with 2.5 x 2.5 km resolution in the visible and 5 x 5 km resolution in the infrared. The spectral range is 0.5 to 12.5 m and the temporal resolution 30 minutes (48 images per day). See the VISSR Web site.
