Investigation of the causes of land surface temperature changes in Khorramabad

Abstract

development of remote sensing applications has led to their use in a wide range of environmental studies. One of these aspects is urban studies and especially land surface temperature. In this study, the changes in land surface temperature in the Khorramabad city in Iran were investigated and the causes of land temperature changes were investigated. For this purpose, Landsat satellite images were processed in four periods of 2000, 2007, 2014 and 2021 and were recovered using a single-channel surface temperature algorithm. Temperatures were high in 2000 due to the type of roofs of buildings and the dirt around the city. Decreased in 2007 and 2014 due to the use of roofs that reflect light. In 2021, due to severe manipulations around the city and the destruction of vegetation and change it into built-up bare soil cover caused the temperature to rise again in the suburbs.
