Copernicus High Resolution Snow and Ice Monitoring: Persistent Snow Area (raster 20m), Oct. 2020
The Copernicus Persistent Snow Area (PSA) product is directly derived from the Fractional Snow Cover (FSC) information. It is generated on a yearly basis for the entire EEA38 and the UK and provides the extent of the persistent snow cover, i.e. the area where snow is present throughout the hydrological year with a spatial resolution of 20 m x 20 m.
PSA is one of the products of the pan-European High-Resolution Snow & Ice service (HR-S&I), which are provided at high spatial resolution (20 m x 20 m), and are derived from the Sentinel-2 constellation data. They are generated over the entire EEA38 (32 member countries and 6 cooperating countries) and the United Kingdom, from September 1, 2016 onwards. Four types of HR-S&I products are proposed to users: the Fractional Snow Cover (FSC) product, the Persistent Snow Area (PSA) product, the River and Lake Ice Extent (RLIE) product and the Aggregated River and Lake Ice Extent (ARLIE) product.
