Abstract:
In order to understand the applicability of the soil moisture data derived from Sixth International Coupling Model Comparison Program (CMIP6) in the Tibetan Plateau, the soil moisture products from Global Land Data Assimilation System (GLDAS) Noah model were used to evaluate the soil moisture data of the CMIP6 Historical experiment. The results show that the ensemble mean soil moisture of CMIP6 is generally higher than that of Noah products while the seasonal variation is significantly smaller than that of Noah products in the Tibetan Plateau. The soil moisture simulated by each model is quite different. Evaluated from the four dimensions of deviation, linear correlation, standard deviation, and field correlation, the best performing models are AWI-ESM-1-1-LR, NorESM2-MM, CanESM5, TaiESM1,while EC-Earth3, EC-Earth3-Veg and GFDL-CM4 performed outstandingly in the evaluation of two dimensions. Consideraing four dimensions, ten models such as AWI-ESM-1-1-LR have better applicability in the plateau.
