This dataset contains a high quality operational Environmental Data Record (EDR) of Snow Cover/Depth Fraction (SCF) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS). The VIIRS SCF EDR is based on a 2x2 aggregation of the VIIRS imagery resolution binary snow map at a spatial resolution of 750 meters at nadir during daytime over cloud-free land masses. The algorithm utilizes VIIRS spectral bands I1 (640 nm), I2 (865 nm), I3 (1.61 micron), I5 (11.5 micron), M15 (11 micron), M16 (12 micron), and several VIIRS Intermediate Products (IP) including Cloud Mask (VCM), Aerosol Optical Thickness (AOT), and Cloud Optical Thickness (COT). By default, IDPS VIIRS SCF obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed in four aggregated 86-second granules in Hierarchical Data Format v.5 (HDF5) with metadata attributes included.
