Land cover

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.

PSA is delivered in two different…
