Lake Ice Extent (raster 250 m), Continental Europe, daily - version 2

The Lake Ice Extent (LIE) is monitored using optical and thermal infrared satellite data, and it classifies a section of the freshwater body on a daily basis 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 the 1st, onwards. In June 2024, the data input sensor was transferred from Terra MODIS (VERSION 1.2.1) to NOAA-20 VIIRS (VERSION 2.2.1), and the area was extended from the Baltic region to cover Continental Europe.
Classification is provided only for cloud free pixels, with a dedicated cloud mask. The gridded data product covers Continental Europe with 250 m (0.0025 degree) resolution; however, original VIIRS data were in 375 m resolution. The LIE product can have several important applications from climate change monitoring and hydrological forecasting to winter transport and recreational activity on lakes.
