Snow Cover Extent 2025-present (raster 1 km), global, daily - version 1
Snow cover is highly sensitive to changes in temperature (freezing/thaw) and precipitation (snowfall, rain, hail) and affects directly the albedo and thus the energy balance of the Earth’s surface. It is a relevant input parameter for weather forecasts and climate change observations. Snow stores a significant mass of water and, with its high dynamic, has a strong effect on regional and global energy and water cycles. Together with the Snow Water Equivalent (SWE) product from passive microwave sensors, that provides information on the water content in the snow on plain areas, up-to-date knowledge about the snow cover extent is an important information for hydrological runoff modelling and for assessing natural hazards such as flood events.
Snow cover is specified as Essential Climate Variable (ECV) by the Global Climate Observing System (GCOS).

- Purpose
-
This product is first designed to fit the requirements of the Global Land Monitoring Service of Copernicus. It can be also useful for all applications related to the environment monitoring, climate research and hydrology.
- Credit
-
The SCE products are generated by the Copernicus Land Monitoring Service, the Earth Observation programme of the European Commission. The research leading to the current version of the product has received funding from various European Commission Research and Technical Development programs. The product is based on Copernicus Sentinel-3A and Sentinel-3B SLSTR (copyright EU Copernicus and distribution by ESA) 1 km data for the main service, and on NOAA-20 VIIRS 750 m data (copyright NOAA) for the backup service.

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.
