Daily snow cover map of Europe (Copernicus)

CLMS SCE Europe 500m daily V1
cryosphere ESA ESA Copernicus active COGNetCDF
In plain English

What it measures. For each 500-metre patch of ground across Europe, it shows what share is covered by snow, from 0 to 100 percent. It even accounts for snow lying under forest canopy.

How it's made. ESA Copernicus builds it from the MODIS instrument aboard NASA's Terra satellite, updated daily in near real time.

How & where you'd use it. Helps forecasters, water managers, and ski regions track where snow is sitting and melting, and feeds flood and water-supply predictions.

Official description

Provides for Europe daily updates of the fraction of snow cover on the ground (also in forested areas) per pixel in percentage (0% to 100%). The data is available in near real time in the spatial resolution of 500 m and with the temporal extent from March 2017 to present.
