Abstract
Much recent scientific focus has been on the impact of climate change on human and natural environments. However, a particular research gap that we address is evaluating the effect of global warming on land surface temperatures across different spatial contexts, such as elevation, in mountain regions. Our aim is to establish the effect of global warming on daytime land surface temperatures at various elevations and slope aspects of the central Alborz Mountains in northern Iran. The land surface temperature (LST) component is extracted from MODIS Terra sensor satellite images for the period 2001-2021 on a monthly basis (240 images were used). Results indicated that increasing surface temperature trends are more pronounced than decreasing trends. Significant increasing surface temperature trends are observed for the months of January through December and June through July. In contrast, October records significant decreasing trends across all study areas and geographic domains. Rates of surface temperature increases are lower in the northern zones compared to the southern zones of the Central Alborz, for elevations ranging from 1500 to 4000 m above sea level. A key finding is that global warming has increased surface temperatures on both the northern and southern aspects of the western and mid regions of the Central Alborz Mountains, while no changes are noted for the eastern region.
