Addditional information available at http://www.met.rdg.ac.uk/~swsgrime/artemis/ch2/other/other.html [Source: National Snow and Ice Data Center, http://nsidc.org/data/docs/daac/seasat_platform.gd.html ] The VIRR identified cloud, land, and water features on the SEASAT mission. It operated in the visible band (0.49-0.94 micrometers) and in the infrared band (10.5-12.5 micrometers). The swath of the VIRR is approximately 2280 kilometers wide, centered on nadir. Spatial coverage for the mission was global, and temporal coverage spanned July 4, 1978 to August 27, 1978. The normal scan period was 1.25 seconds, and 48 scans were completed per minute.
