High Resolution Snow and Ice Monitoring: SAR Wet Snow (raster 60m)
The Copernicus SAR Wet Snow (SWS) product is generated in near real-time for the entire EEA38 and the United Kingdom, based on radar satellite data from the Sentinel-1 constellation. The product provides binary information on the wet snow extent and the snow free or patchy snow or dry snow extent in high mountain areas with a spatial resolution of 60 m x 60 m.
The SWS product is distributed in raster files covering an area of 110 km by 110 km with a pixel size of 60 m by 60 m in UTM/WGS84 projection, which corresponds to the Sentinel-2 input L1C product tile. It is available in several mountainous regions in Iceland, the Pyrenees, the Alps, Eastern Türkiye and Scandinavia. Each product is composed of two separate GeoTIFF files corresponding to the different layers of the product, and a metadata file.The WSM (Wet Snow classification in high Mountainous areas) layer provides the wet snow extent derived from S1 Level 1 GRD data over high montainous areas, and the QCWSM (Quality) layer provides the per-pixel accuracy information associated with the WSM layer for all pixels with detected snow areas.
The SWS 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 60 m x 60 m), from the Sentinel-2 and Sentinel-1 constellations data from September 1, 2016 onwards.

The Copernicus component is governed by Regulation (EU) No 2021/696 of the European Parliament and of the Council of 28 April 2021 establishing the Union Space Programme and the European Union Agency for the Space Programme and repealing Regulations (EU) No 912/2010, (EU) No 1285/2013 and (EU) No 377/2014 and Decision No 541/2014/EU. Within the Copernicus component, a portfolio of land monitoring activities has been delegated by the European Union to the European Environment Agency (EEA) and the DG Joint Research Centre of the European Commission.
The Copernicus land monitoring products and services are made available on a principle of full, open and free access, as established by the Commission Delegated Regulation (EU) No 1159/2013 of 12 July 2013.
Free, full and open access to the products and services of the Copernicus Land Monitoring Service is made on the conditions that:
1. When distributing or communicating Copernicus Land Monitoring Service products and services (data, software scripts, web services, user and methodological documentation and similar) to the public, users shall inform the public of the source of these products and services.
2. Where the Copernicus Land Monitoring Service products and services have been adapted or modified by the user, the user shall clearly state this.
3. Users shall make sure not to convey the impression to the public that the user's activities are officially endorsed by the European Union.
