资源简介：
This dataset includes the monthly gap-filled CCI combined soil moisture from 1982 to 2020, the spatial resolution is 0.25°. The product is generated by XGBoost and the used covariates of soil moisture include precipitation, albedo, surface temperature, air temperature and soil moisture from CMA-RA/Land reanalysis data; NDVI from GIMMS and MODIS; GTOPO30 DEM; soil texture from HWSD; and temporal information. The overall correlation coefficient R and root-mean-square error (RMSE) compared the 5cm-depth observations from ISMN (192 sites) is 0.554 and 0.0977 cm3cm-3 which is slightly better than the original CCI data.
