There are several RLIE products available for the entire EEA38 and the United Kingdom, depending on their data source. RLIE S1 and RLIE S2 are generated in near real-time based on observations from the Sentinel-1 and the Sentinel-2 constellations respectively while RLIE S1+S2 is a delayed-time product derived from the previous products - an RLIE S2 for a given day is enriched with RLIE S1 of the same day. All RLIE products are 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 L1C product tile. They inform of the presence of snow-covered or snow-free ice on the various water bodies described by the EU-HYDRO river and lake network database. Each product is composed of three separate files corresponding to the different layers of the product, and another metadata file. The RLIE products are part 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.

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. 801dc3ca-339d-4e27-9a18-08b6934efe34 grid 20 utf8 environment imageryBaseMapsEarthCover climatologyMeteorologyAtmosphere 2016-09-01 -26.00 44.00 34.00 66.00 GeoTIFF 1.0 https://cryo.land.copernicus.eu/wms/RLIE?service=WMS&request=GetCapabilities&version=1.3.0 OGC:WMS https://cryo.land.copernicus.eu/wms/RLIE?service=WMS&request=GetCapabilities&version=1.3.0 https://land.copernicus.eu/en/products/water-bodies/high-resolution-river-and-lake-ice-extent#download WWW:DOWNLOAD CLMS Website Download (requires authentication) https://wekeo.copernicus.eu/data?view=catalogue&facets=contactOrg%7EEuropean+Environment+Agency WWW:DOWNLOAD WEkEO Portal Download (requires authentication) https://land.copernicus.eu/en/products/water-bodies?tab=river_and_lake_ice_extent WWW:LINK Product Information & Technical Documentation https://cryo.land.copernicus.eu/finder/ WWW:DOWNLOAD CRYO Portal Download (requires authentication) Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08 publication See the referenced specification The Sentinel-2 L1C product is converted into L2A using the MAJA processor, which performs atmospheric correction and provides an accurate cloud mask. A supervised classification method using multi-spectral indices is performed on L2A images. Pixels are assigned to one of the following classes: (1) open water, (2) snow-covered or snow-free ice and (3) other features (mainly vegetation and bare soil).
