THE SCALING-UP OF PROCESSES IN THE HETEROGENEOUS LANDSCAPE OF HEIFE WITH THE AID OF SATELLITE REMOTE-SENSING

To improve understanding of the processes of land surface-atmosphere i nteraction at a scale of 10(4) km(2) in HEIFE, the utilization of sate llite 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 w ell 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 albed o, vegetation index, surface temperature, net radiation and other basi c energy balance components of the whole area. Statistical analysis ba sed on these maps revealed some quantitative significant land surface parameters. Future developments were discussed.
