QA4SM
The Quality Assurance for Soil Moisture project (QA4SM) provides an operational online validation service for soil moisture products. Accessible at www.qa4sm.eu [2]
DataViewer
Monthly averages of the ESA CCI SM data are hosted on a public data viewer available at https://dataviewer.geo.tuwien.ac.at [3]
C3S Climate Data Store
The ESA CCI SM algorithm is used to generate C3S Soil Moisture data products available through the Copernicus Climate Data Store [4]. This data in generated with a delay of a few days and therefore recommended especially for near-real-time applications. The climate data store provides a large number of different climate variables, background information on their generation, an easy to use web UI as well as an API to access the data.
