    "title": "Daily Global Multi-sensor Automated Snow and Ice (GMASI) Map",
    "description": "The daily gridded, snow and ice coverage map is a blended product generated by the Automated Snow and Ice Mapping System (GMASI). The map is produced from Level-1 observations obtained by the AVHRR, AMSR2, and GMI instruments, onboard the MetOp-B, MetOp-C, GCOM-W, and GPM satellites. GMASI was developed to facilitate the operational monitoring of snow and ice cover and to provide Cryosphere status information to Numerical Weather Prediction (NWP) models. The system employs a completely automated data processing algorithm to infer the distribution of global snow and ice cover from satellite observations. The retrieval algorithm utilizes combined observations from the visible\/infrared and microwave spectral bands. The daily snow map provides a continuous (gap free) characterization of global snow and ice cover generated on a latitude-longitude grid (Plate Carree) with a resolution of 0.02 degrees (or about 2 km grid cell size). 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 netCDF-4 file format with attributes included.",
