Successful monitoring and modelling climate change in water, energy and carbon cycles in the Pan-Third Pole Environment (CLIMATE-Pan-TPE) demands improved understanding of the interaction between the Asian monsoon, the Tibetan Plateau surface, and the plateau atmosphere in terms of the water and energy budget. CLIMATE-Pan-TPE aims to verify or falsify recent hypotheses, which include the links between plateau heating and monsoon circulation, snow cover and monsoon strength, soil moisture and timing of monsoon. We analysed the mechanistic bases for projections of the changes of glaciers and permafrost in relation to surface and tropospheric heating on the Tibetan Plateau, and their impacts on water resources in South East Asia. More specifically we will report the following results: (1) a long-term (2005-2016) hourly dataset of the integrated land-atmosphere interaction observations from six field stations over the Tibetan Plateau; (2) monthly actual evapotranspiration and its spatial distribution on the TP (2001-2018) using the Surface Energy Balance System (SEBS) model with satellite products and meteorological reanalysis data as input; (3) hourly land surface heat fluxes and evapotranspiration estimated based on multisource remote sensing data; (4) a monthly 0.01° terrestrial evapotranspiration product for the TP (1982-2018) using the MOD16-STM equation; (5) methods for estimating surface soil moisture, monitoring and predicting freeze-thaw states and quantifying soil ice content with microwave remote sensing data, (6) estimation of the total annual evaporation amounts over the entire TP lakes as 51.7±2.1 km³ year^-1, with a plausible hypothesis of near-zero heat storage during ice-free season and near-constant ice sublimation during winter; and (7) the water vapor channel of the Yarlung Zangbo Grand Canyon (YGC) in the southeastern TP was investigated by establishing a three-dimensional comprehensive observation system of mountain land-air interaction, water vapor transport, cloud cover, and rainfall activity. The observation datasets will benefit future research on mountain meteorology.
