VIIRS/JPSS2 Snow Cover Daily L3 Global 375m SIN Grid V002
Listed in NASA Earthdata CMR
This data set contains daily snow cover derived from radiance data acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Joint Polar Satellite System's second satellite (JPSS-2).
Description
The data is a gridded composite, generated from 6 minute swaths, and projected to a 375 m Sinusoidal grid. Snow cover is identified using the Normalized Difference Snow Index (NDSI) and a series of screens designed to alleviate errors and flag uncertain snow cover detections.
