Abstract  

The Qinghai-Tibet Plateau has a special geographical location and remarkable environmental characteristics, and it is a key participant and decision-maker in the role of the Earth system. Using large-scale satellite microwave remote sensing data to study soil moisture can not only provide theoretical support for understanding the quantitative impact of typical regions on the global water, air, energy and heat interaction mechanism, but also provide practical basis for confirming the reliability of remote sensing data. Based on SMOS (2011—2020) and SMAP (2016—2020) satellite soil moisture data, supplemented by ISMN data, GPCP precipitation data, MOD16A2 evapotranspiration data and C3S surface landcover data, this paper studied the temporal and spatial variability of soil moisture over the Tibetan Plateau during the monsoon and vegetation growing season. Based on the annual mean value of soil moisture(θsatˉ) and the correlation coefficient between soil moisture and time (Rxt), the temporal and spatial distribution and long-term dissipation characteristics of soil moisture in the monsoon and vegetation growing season (July-September) of the Qinghai-Tibet Plateau were studied. Combined with the partial correlation coefficient (Rxy,z) the coupling relationship between precipitation and evapotranspiration was preliminaries analyzed. The results showed that the soil moisture decreased first (2011—2015) and then increased (2015—2018) and volatility change subsequently in time, and gradually increased from northwest to southeast in space. The coupling between soil moisture and precipitation was stronger than evapotranspiration in most areas of the Tibetan Plateau. SMOS and SMAP have a high consistency in capturing spatial and temporal characteristics of soil moisture over the Tibetan Plateau.
