VIIRS/NPP Snow Cover Daily L3 Global 375m SIN Grid V001

Published by NASA NSIDC DAAC | National Aeronautics and Space Administration | Metadata Last Checked: October 20, 2025 | Last Modified: 2025-07-17

This data set contains daily snow cover derived from radiance data acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Suomi National Polar-orbiting Partnership (NPP) satellite. 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.
