Description

This paper aims to extract land surface temperature change in Tokyo and to analyze relation ship between land surface temperature change and land cover change. Land surface temperature patterns were derived from LANDSAT/TM Band6 data acquired at night in the summer of 1984 and 1994.Land cover patterns were obtained by the classification of TM data of corresponding periods. The higher-temperature zone had expanded from the center part of Tokyo to the suburbs in the west which had been urbanized in ten years. Land surface temperature change in the areas urbanized before 1984 was also investigated.In those areas, temperature difference between the city center and the surrounding regions reduced in ten years and it was proved that the reduction rate correlated with the urbanization rate. These results indicate that land surface temperature in the suburbs has been getting higher and closer to that of the city center in Tokyo due to urbanization.
