This dataset contains a high quality operational Environmental Data Record (EDR) of snow cover from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). This product provides both binary (snow or no-snow) and fractional snow cover for cloud-free areas during daytime. The product also includes quality information which provides support information on the quality of snow retrievals. The algorithm utilizes VIIRS visible bands I1 (0.640 micron), I2 (0.865 micron), I3 (1.61 micron), I4 (3.74 micron), and I5 (11.5 micron) at a spatial resolution of 375 meters. VIIRS Snow Cover products distributed by the NESDIS Data Exploitation system (NDE) and obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed in single 86-second granules in NetCDF-4 format with metadata attributes included.
