Surface Urban Heat Island Assessment of a Cold Desert City: A Case Study over the Isfahan Metropolitan Area of Iran Academic Article uri icon

abstract

  • This study investigates the diurnal, seasonal, monthly and temporal variation of land surface temperature (LST) and surface urban heat island intensity (SUHII) over the Isfahan metropolitan area, Iran, during 20032019 using MODIS data. It also examines the driving factors of SUHII like cropland, built-up areas (BI), the urbanrural difference in enhanced vegetation index (EVI), evapotranspiration (ET), and white sky albedo (WSA). The results reveal the presence of urban cool islands during the daytime and urban heat islands at night. The maximum SUHII was observed at 22:30 p.m., while the minimum was at 10:30 a.m. The summer months (June to September) show higher SUHII compared to the winter months (February to May). The daytime SUHII demonstrates a robust positive correlation with cropland and WSA, and a negative correlation with ET, EVI, and BI. The nighttime SUHII displays a negative correlation with ET and EVI.
