The Copernicus Land Monitoring Service (CLMS) would like to draw your attention to the release of a new range of High Resolution Snow & Ice (HR-S&I) Monitoring products.
These products are now operationally available and include:

  •     Fractional Snow Cover (FSC)
  •     Persistent Snow Area (PSA)
  •     River and Lake Ice Extent (RLIE)
  •     Aggregated River and Lake Ice Extent (ARLIE)

These products provide snow and ice information over EEA-39 countries at high resolution (20 m x 20 m) and are derived from the Sentinel-2 constellation (Sentinel-2A and Sentinel-2B) observations. 
The FSC and the RLIE are made available in near real-time, according to the Sentinel-2 revisit period (5 days). The temporal aggregated products, PSA and ARLIE products are generated periodically. More information on the HR-S&I products are available online here. This includes an overview of processing algorithms, technical product content and format and main validation results. 

You can download HR-S&I Monitoring products here.

Please note, an additional tool is provided to allow for a more sophisticated interactive web map service enabling a better viewing and browsing through the HR-S&I catalogue.

For any technical issues or additional information related to the HR-S&I products, please refer to the FAQ section or contact us via the CLMS service desk.
To introduce Users to these new products an introduction webinar will be held on the 15th & 16th of October 2020 (9:30-12:00 on both days). You can register for the event here.
Please note you are welcome to forward the information to other colleagues who might have an interest in snow or ice products.  
Stay tuned via the CLMS and European Environment Agency social media channels (Twitter, and Facebook)!
