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. Fraction of snow cover provides an important input to numerical weather prediction, hydrological, and climate models. onGoing DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce Customer Engagement Branch 1-828-271-4800 1-828-271-4876 151 Patton Avenue Veach-Baley Federal Building, Room 468 Asheville NC 28801-5001 USA ncei.orders@noaa.gov https://www.ncei.noaa.gov HTTPS Web Browser NOAA National Centers for Environmental Information (NCEI) NCEI home page with information, data access and contact information. information 8:00 - 6:00 Eastern pointOfContact continual https://www1.ncdc.noaa.gov/pub/data/metadata/images/C01436.PNG Example of Suomi NPP VIIRS NDE Snow Cover - Northwest Global Quadrant from March 29, 2016.
