This dataset contains soil moisture estimates with worldwide coverage from a variety of satellite sources. Based on the ESA Climate Change Initiative soil moisture version 03.3, it meets the requirements of the “Systematic observation requirements for satellite-based products for climate” by the Global Climate Observing System (CGOS). Data are presented on a standard latitude/longitude grid with some notable voids.
The CDR (Climate Data Records) and ICDR (interim-CDR) parts of each product were produced using the same methodology. The CDR provides the robustness for detecting climate variabilities and changes over time, whereas the ICDR provides access to recently collected while remaining consistent with the CDR baseline, but is not rigorously verified. The dataset contains the following data products: "active", "passive", and "combined". "Active" and "passive" are based on scatterometer and radiometer soil moisture products, while the "combined" product is based on a blend of the s two.
This dataset is created as part of the Copernicus Climate Change Service (C3S).
| Variable Name | Unit | Description |
