A Multi-Sensor Assessment of Urban Heat-Islands

Data acquired during the early to mid-1990s by several satellite-sensor systems were combined in an assessment of the urban heat-island effect in the Dallas-Ft. Worth, USA, region. The sensors included in this study provide information on the vegetation characteristics (AVHRR and Landsat-MSS), radiant surface temperature (AVHRR), land use/land cover (Landsat-MSS), and anthropogenic light emitted by urban-related surface features (DMSP-OLS). The urban and rural differences in the above variables were determined and will be discussed.
