The Theia Sentinel-2 Snow Cover Level-2B dataset provides snow cover data from Sentinel-2 mission with a 5-day revisit and a spatial resolution of 20 m. The dataset is organized into the original Sentinel-2 UTM Tiling Grid. Each of these tiles covers an area of 110 km x 110 km. Theia Products are generated over selected tiles. For justified research needs, it is nevertheless possible to request additional regions, subject to production capacity.
Each product contains two raster files and a metadata file:
