The Scaling-up of Processes in the Heterogeneous Landscape of HEIFE with the Aid of Satellite Remote Sensing

Abstract

To improve understanding of the processes of land surface-atmosphere interaction at a scale of 10⁴km² in HEIFE, the utilization of satellite remote sensing is indispensable. Landsat TM observation, because of its high spatial resolution, can be compared directly with surface measurements and be used for this purpose. The relevant data set as well as a state-of-the-art data processing methodology are discussed. A summer scene of TM was used to produce a set of maps of surface albedo, vegetation index, surface temperature, net radiation and other basic energy balance components of the whole area. Statistical analysis based on these maps revealed some quantitative significant land surface parameters. Future developments were discussed.
