Daily Automated Snow and Ice Cover Maps for the Northern Hemisphere and Southern Hemisphere

This AutoSnow product provides daily, gridded, snow and ice coverage maps for the Northern and Southern Hemispheres. The maps are produced from Level-1 observations obtained by the AVHRR, AMSU, GMI, and GMS instruments, onboard MetOp, GOES, and Meteosat satellites. The daily snow map provides a continuous (gap free) characterization of hemispheric snow and ice cover generated on a latitude-longitude grid at a 4 km resolution. The data are produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS) and are distributed by the Comprehensive Large Array-Data Stewardship System (CLASS) as daily gridded files in the GRIB format.
