Copernicus High Resolution Water Snow and Ice Monitoring: Fractional Snow Cover (FSC) 20m

The Fractional Snow Cover (FSC) product is generated in near real-time at European scale based on optical satellite data from the Sentinel-2 constellation (revisit time: 5 days with Sentinel-2A and Sentinel-2B). The product provides the fraction of the surface covered by snow at the top of canopy (FSC-TOC) and on ground (FSC-OG) per pixel as a percentage (0% – 100%) with a spatial resolution of 20 m x 20 m.
FSC is one of the products of the pan-European High-Resolution Water Snow & Ice portfolio (HR-WSI), which are provided at high spatial resolution from the Sentinel-2 and Sentinel-1 constellations data from September 1, 2016 onwards.
The FSC product is distributed in raster files covering an area of 110 km by 110 km with a pixel size of 20 m by 20 m in UTM/WGS84 projection, which corresponds to the Sentinel-2 input L1C product tile. Each product is composed of separate files corresponding to the different layers of the product, and another metadata file.
