| Abstract: | 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. |
