Daily lake ice and snow map for Europe, from the NOAA-20 satellite's VIIRS sensor (250 m detail)

CLMS LIE Europe 250m daily V2
cryosphere ESA ESA Copernicus active COGNetCDF
In plain English

What it measures. Classifies freshwater bodies across continental Europe each day as fully snow-covered ice, partly snow-covered or bare ice, or open water, on a pixel-by-pixel basis.

How it's made. Produced by ESA Copernicus from the VIIRS instrument aboard the NOAA-20 satellite, at about 250-metre detail and in near real time.

How & where you'd use it. Useful for monitoring lake freeze and thaw cycles, supporting cold-region studies, navigation and climate tracking. This newer version runs from July 2024 to the present.

Official description

On a daily basis, classifies pixels of Continental Europe freshwater bodies as 1) Fully snow-covered ice, 2) Partially snow-covered or snow-free ice, and 3) Open water. The data is available in near real time in a spatial resolution of 250 m and with the temporal extent from July 2024 to present, derived from NOAA-20 VIIRS.
