1 Determination of Surface Heat Fluxes and Evapotranspiration(ET) over Heterogeneous Landscape of the Third Pole Region (Tibetan Plateau and nearby surrounding region) Yaoming Ma 1. Institute of Tibetan Plateau Research, Chinese Academy of Scien 2. CAS Center for Excellence in Tibetan Plateau Earth Sciences, CA 3. University of Chinese Academy of Sciences 4. Qomolangma Station for Atmospheric and Environmental Observation and Research, CAS (17-19 October 2016,Grenoble, France)

2 Cold air Western wind Atmospheric heating source Warm water vapor

3 Tibetan Plateau Heating to the atmosphere Energy fluxes and water vapor flux exchange between the land surface and near surface atmosphere

4 Heterogeneous land surface(different ecosystems) Plateau Mountain Desertification grass-land How to get the regional surface heat fluxes and ET over the Third Pole Plateau forest region Plateau Gobi desert??????????? Grass land Glacier (snow mountain) Plateau lake Farm-land Wet-land

5 1. Set up observation stations at different land surfaces(ecosystems) Observation Data analysis Heat fluxes and ET at each land surface Satellite data Models Parameterization Modeling understanding of regional surface fluxes and ET over the Third Pole region LDAS
