Daily lake ice and snow map for Northern Europe (Copernicus)

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.
