摘要：

The net radiation, ground heat flux, sensible heat flux and latent heat flux over the Northern Tibetan Plateau at different times of the day were estimated by using land surface observation, the surface energy balance system algorithm, and FY-2E geostationary meteorological satellite visible infrared and FY-3B polar-orbiting satellite microwave remote data. The results from the model agree well with the ground observations from Naqu Alpine Climate Stations with 28.22 W·m-2 RMSE in hourly scale. The condition expectation of surface energy components during the summer time of the Northern Tibet were analyzed, and different surface temperature corresponds to the effective energy distribution were also discussed. The results shows regional ET was ranged between 2.0~4.0 mm over the Northern Tibetan Plateau. ©, 2015, Chinese Optical Society. All right reserved.
