The River and Lake Ice Extent - Sentinel 1 (RLIE S1) product is part of the Copernicus Land Monitoring Service (CLMS), pan-European High Resolution Snow and Ice Monitoring (HR-S&I) Ice product suite.The River and Lake Ice Extent (RLIE) products measure the presence of ice in rivers and lakes described by the EU-HYDRO network database, in particular the area of snow-free or snow-covered ice. The RLIE S1 product is released in near real time for the entire EEA39 zone based on the revisit time of the Sentinel 1 syntetic aperture radar constellation, and it is generated at a spatial resolution of 20 m x 20 m. Because it is time critical for several applications, every effort is made to provide near real time ice products between 6 and 12 hours after the data sensing time. More information about the RLIE S1 product methodology and workflow is outlined in the product user manual. A detailed explanation about the accuracy of the product can be found in the quality assessment report.
