Description:

The Soil Moisture CCI datasets include three datasets (ACTIVE, PASSIVE, and COMBINED) that were created as part of the European Space Agency’s (ESA) Soil Moisture Essential Climate Variable (ECV) Climate Change Initiative (CCI) project. These products, provided as global daily images in NetCDF-4 classic file format, present a global coverage of surface soil moisture at a spatial resolution of 0.25 degrees.
The ACTIVE product has been created by fusing scatterometer soil moisture products, derived from the instruments AMI-WS and ASCAT. It is provided in percent of saturation [%] and covers the period 1991-08-05 to 2020-12-31.
The PASSIVE product has been created by merging data from the SMMR, SSM/I, TMI, AMSR-E, WindSat, AMSR2, SMOS, SMAP, FY-3B and GPM satellite instruments. It is provided in volumetric units [m3 m-3] and covers the period 1978-11-01 to 2020-12-31.
The COMBINED product has been created by directly merging Level 2 scatterometer and radiometer soil moisture products derived from the AMI-WS, ASCAT, SMMR, SSM/I, TMI, AMSR-E, WindSat, AMSR2, SMOS, SMAP, FY-3B and GPM satellite instruments. It is provided in volumetric units [m3 m-3] and covers the period 1978-11-01 to 2020-12-31.
For information regarding the theoretical and algorithmic base of the product, please see the Algorithm Theoretical Baseline Document. Additional reference documents and information relating to the dataset can also be found on the CCI Soil Moisture project website.
