摘要:

利用天宫一号高光谱红外谱段,结合准同步的Aqua MODIS (MYD021KM) 资料,在对地表特征参数估算的基础上,利用地表能量平衡系统模式计算藏北高原地区的地表通量与蒸散量.结果表明基于天宫一号高分辨率高光谱红外谱段的地表通量与蒸散量估算结果和地表实际状况吻合,具有很大的应用潜力.

Estimation of turbulent heat fluxes and evapotransporation over the Tibetan Plateau from Thermal IR imaging based on Tiangong-1
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.
