NOAA JPSS Visible Infrared Imaging Radiometer Suite (VIIRS) Snow Cover Environmental Data Record (EDR) from NDE

Dataset Identification:

Resource Abstract:
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.

measure Description  The Data Stewardship Maturity Matrix (DSMM) is a unified framework that defines criteria for each of nine components based on measurable practices, which can be used to apply a progressive, 6-level rating to an individual dataset, representing stewardship maturity stages rated as Not Assessed or Not Available (Level 0), adHoc (Level 1), minimum (Level 2), intermediate (Level 3), advanced (Level 4), and optimal (Level 5).
evaluation Method Description  Data Stewardship Maturity Assessment was evaluated by the metadata content editor for the NOAA OneStop project using the Scientific Data Stewardship Maturity Assessment Model Template v4.0.
