Abstract

Based on the Tiangong-1 Thermal IR imaging and quasi synchronous Aqua MODIS data (MYD021KM)

the land surface characteristic parameters were retrieved firstly. Then the surface turbulent heat fluxes and daily evapotransporation over the northern Tibetan Plateau area were derived by using Surface Energy Balance System (SEBS). The results show that the estimated surface turbulent heat fluxes and daily evapotransporation from Thermal IR imaging are in good accordance with land surface status.
