Abstract:The purpose of this study is to evaluate the influence factors, improvement conditions and overall adaptability of hydrological models in the Tibetan plateau area. Two important indicators include using GRACE-derived terrestrial water storage (TWS) to compare with outputs from GLDAS, and using rainfall and temperature from in-situ measurements to compare with inputs from GLDAS. This paper uses correlation and error analysis to evaluate the input parameters of GLDAS, and compares it with the actual observation data as model prediction data. Results show that the indicators of GLDAS/Noah are in good agreement with GRACE. The annual amplitude and phase of rainfall and temperature data present higher coefficient of NSE and high consistency between the GLDAS model and the ground observation data.
