Abstract

Heat island phenomenon, in which city air temperature is higher than that in the rural area, was evaluated by remote sensing techniques. The sensible heat transfer coefficient was determined by an infrared remote sensing observation. To overcome the problem of heterogeneous surface temperature, the IR-image of enough spatial resolution determined the effective surface temperature on urban area. The obtained heat transfer coefficient calculates air temperature change due to the change of buildings structure under the typical summer condition. In the calculation, the mixed layer depth obtained by laser remote sensing observation was used. The city's impact on the local climate was shown to depend on the building structures.
