Daily lake ice and snow map for northern Europe, from Copernicus satellites (250 m detail)

CLMS LIE Baltic 250m daily V1
cryosphere ESA ESA Copernicus COGNetCDF
In plain English

What it measures. Each day labels Northern European lakes and freshwater bodies as fully snow-covered ice, partly snow-covered or bare ice, or open water, mapped pixel by pixel.

How it's made. Produced by ESA Copernicus from the MODIS satellite instrument at about 250-metre detail, delivered close to real time.

How & where you'd use it. Helps track winter freeze-up and spring thaw on lakes, supporting cold-region research, navigation and climate monitoring. This version covers March 2017 to June 2024.

Official description

On daily basis for Northern Europe classifies, in pixels, inland/freshwater bodies as 1) Fully snow-covered ice, 2) Partially snow-covered or snow-free ice, 3) Open water. The data is available in near real time in the spatial resolution of 250 m and with the temporal extent from March 2017 to June 2024.
