2023-04-03 Monthly gap-filled CCI soil moisture over region of China (Combined Product) doi:10.57760/sciencedb.07849 en 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. microwave soil moisture; machine learning; gap-filled product; combined product; China Hao Sun Xu Qian Zhiyu Zhao PUBLIC https://creativecommons.org/publicdomain/zero/1.0/ dataset http://www.doi.org/https://doi.org/10.3390/rs13142848 Science Data Bank
