 Zusammenfassung: While Europe is impacted by more frequent extreme hydrological events such as severe droughts or devastating floods, monitoring water resources is a growing challenge. Since July 2020, under European Environment Agency (EEA) delegation, the Copernicus Land Monitoring Service (CLMS) operationally produces and disseminates Pan-European High-Resolution Snow & Ice products (HR-S&I) in near-real time. These products are generated over Europe (EEA38 and the United Kingdom). They benefit from high spatial resolution (20 m x 20 m and 60 m x 60 m) as they are derived from Sentinel-2 constellation optical data and Sentinel-1 constellation radar data.;There are multiple snow cover products in the portfolio. The Fractional Snow Cover (FSC) product is generated from Sentinel-2 observations and provides for each pixel the snow cover fraction (0% – 100%). The daily cumulative Gap-filled Fractional Snow Cover (GFSC) is an aggregated daily snow cover map based on the FSC and is enriched with classifications from the radar data. In mountain areas, radar data allow the detection of the wet snow extent during melting conditions - the SAR wet snow (SWS) product -; independent of any cloud cover affecting the optical satellite data.;This Copernicus service component is based on pre-existing algorithms which have been turned into operational conditions, based on the WEkEO DIAS European cloud infrastructure.;We will present the different products with an overview of the algorithms and their validation over Europe, detail the data access and give insights of applications for hydrology.
