ABSTRACT
This chapter presents the potential of the current EO systems to support surface parameterization in model simulations that were performed in BRIDGE, and also providing some examples of such satellite derived products for the case study of Athens, Greece. EO supported the models used in BRIDGE with detailed (spatially and temporally) information for such parameters as Land Surface Albedo (LSA), Land Surface Emissivity (LSE) and Land Surface Temperature (LST). An LST estimation methodology is exemplified in the following example, where summertime Landsat images over the metropolitan Athens area were analysed. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) stereo imagery has been used in BRIDGE for DEM generation at city and regional scales, for all BRIDGE case studies. The vertical accuracy of a DEM product is assessed using Global Positioning System (GPS) measurements.
