The highlight of this version is the improved time and space coverage, because it includes 3 new active and passive sensors (the observation values of all sensors for the rise and fall overpasses are incorporated into this version for the first time). The verification shows that the new version is the most accurate ESA CCI SM product so far. It provides global data from 1978 to 2021.
The algorithm update includes the following contents:
Including new Fengyun 3C, 3D and ASCAT-C sensors
LPRM v7.1 improves the model parameterization of LPRM. This applies to all passive sensors except SMOS and SMAP using LPRM v06.2
Daytime observations from all passive sensors are now included in the merge
Includes a new optional sign for barren ground
Coordinate sensors using intra year offset correction
The product time range will be extended to the end of 2021.
This data is clipped on the basis of the original data (active passive joint version), and the clipped range is Southwest China.
File name: soil moisture data is stored in TIFF format. The file name is ESACCIyyymdd.tif, where yyyy represents year, mm represents month and dd represents day.
