C3S
The Copernicus Climate Change Service (C3S) provides an operational soil moisture product based on the ESA CCI SM algorithm. A long-term consistent soil moisture climate data record is produced and updated every 10 days with the latest observations; a monthly version is also available. The data can be retrieved from the C3S Climate Data Store (CDS). Part of the quality assurance is undertaken using the ISMN in situ data.
