摘要
利用 1998年淮河流域加密观测试验 (HUBEX IOP)期间的资料 ,进行淮河流域能量平衡的参数化方案的研究 ,用NOAA卫星的AVHRR资料建立了试验区地表特征参数及能量平衡各分量的参数化方程 ,并对卫星遥感反演结果和试验观测值进行了对比 。
To improve understanding of the processes of heterogeneous land surface\|atmosphere interaction,the utilization of satellite remote sensing is indispensable.With the aid of satellite remote sensing and field observational data which observed during intensive observation of Huaihe River Basin energy and Water Cycle Experiment (HUBEX) in 1998,the surface albedo,NDVI (Normalized Difference Vegetation Index) and surface temperature in regional scale of HUBEX could be derived.Then,the distribution of regional energy balance components could be estimated.This work provided the physical foundation for the numerical simulation of the Huaihe river basin energy and water processes,and is important for us to further analyze the regional distribution of surface characteristic parameters and energy balance components with the change of the weather situation in HUBEX in 1998.
