摘要：Variations of surface temperature, albedo, emissivity and net radiation in different urban and rural classes in an arid area were investigated. Four ASTER satellite scenes with channels from the very near infrared to the thermal infrared were analyzed. For a better understanding of the spatial coherences a land use classification was built. The classes were then spatially and temporally compared. The investigations show a distinct daily cool island for Dubai and daily cooling areas of Abu Dhabi city and its surrounding mangrove areas. Net radiation is mainly controlled by the albedo. Therefore the net radiation is higher in the urban areas, where the albedo is lower than in the bright desert areas. The surface temperatures behave contrary to the net radiation and are mostly correlated with the availability of water. This work describes part of the urban-rural climatologically complex and contributes particularly to the different situations of coastal cities in an arid environment
