Where snow is, cloud-gap-filled (VIIRS, Suomi-NPP, 375 m)

VIIRS/NPP CGF Snow Cover Daily L3 Global 375m SIN Grid V002
cryosphere NASA NSIDC_CPRD Level 3 active HDF-EOS5
In plain English

What it measures. Where snow is on the ground each day across the globe, with clouds filled in so the map shows the snow likely hiding underneath cloud cover.

How it's made. Built from the VIIRS daily snow product on the Suomi-NPP satellite, then improved with a 'cloud-gap-filling' step that replaces cloud-blocked pixels with best estimates, mapped to a 375 m grid.

How & where you'd use it. Useful for tracking snow cover for water supply forecasting, flood planning, and climate monitoring without gaps left by clouds.

Official description

This data set contains daily 'cloud-free' snow cover produced from the VIIRS/NPP Snow Cover Daily L3 Global 375m SIN Grid, Version 2 snow cover product. A cloud-gap-filled algorithm is utilized to replace ‘cloud-covered’ pixels with ‘cloud-free pixels’ for the purpose of estimating the snow cover that may exist under current cloud cover. The data are provided daily and mapped to a 375 m sinusoidal grid.
