Estimating the Land surface temperature using the Single Channel algorithm and examining the impact of land use on temperature changes (Case study: Malayer county)

Rising ground temperatures and the creation of urban thermal islands are an important issue in the 21st century. Because it deals with the complex challenges of urban population growth, global climate change, public health, and increasing energy demand for cooling. Therefore, the purpose of this study is to estimate the surface temperature using remote sensing methods such as the Sinlge Chaneel algorithm. For this purpose, satellite images related to the study area were obtained for 9/22/2019. After performing radiometric and atmospheric corrections in Envi software, the satellite image was called in Qgis software, and with this algorithm, the Land surface temperature was estimated, and the results showed that the Land surface temperature fluctuated between 20.55 and 50.55. ° C. Also, from the study of the impact of land use on the temperature of the region, it was found that water resources and natural cover, including Aghgol wetland, have the greatest role in reducing the temperature of the region and the lower classes have a temperature. But, residential uses and barren lands have increased temperatures due to higher heat absorption and are at higher temperatures classes.
