High-Resolution Snow & Ice Monitoring; Persistent Snow Area

Description

The High-Resolution Snow & Ice Monitoring service (HR-S&I) is part of the Copernicus Land Monitoring Service (CLMS). The snow aspect of the service provides products measuring Snow cover (FSC, FSTOC, FSCOG, GFSC), Snow state conditions (WDS, SWS) and persistent snow area (PSA). There are also ice products that measure ice cover (RLIE) and aggregated river and lake ice extent (ARLIE).More information about the data can be found here and the snow products user manual is located here. The Persistent Snow Area (PSA) product is generated annually from FSC products and provides the extent of persistent snow cover for that year (the area where snow is present throughout the hydrological year).
