Abstract

The island's thermal city is one of the most prominent consequences of the expansion of urbanization and metropolitan development. The effects of the formation of thermal islands can play an important role in air quality and, consequently, in general health. The purpose of this study was to investigate the role of surface coatings on climate change in Tehran metropolis. In this study, the required data from bands 10 and 11 of OLI and TIRS sensors of Satellite Landsat 8 in the summer and winter of 2017 were used. To study the thermal island status, single-band classes were used to study the distribution of ground temperature in the Tehran area and determine the local effects of Thermal Island in the city. The relationships between surface temperature and other variables i. e. vegetation cover, city structural features and wasteland area were calculated in order to determine the effects of green, bare, blue and residential land on thermal island. The results showed that the effect of Isle of Man in the northern regions of the city is due to the existence of industrial activities and mountain topography. There is also a correlation between ground temperature and Tehran's vegetation index, as the surface temperature of the city increases with decreasing vegetation. Finally, according to research findings, practical proposals have been presented.
