Abstract :Climate change and its effects, which are increasing day by day, and adversely affect the human life. The world\'s average temperature trend is tend to increase and the precipitation regime is changing with the effects of climate change. In this study, changes in Land Surface Temperature and Normalized Difference Vegetation Index were calculated and mapped in Mus province for the years 2013-2018 and 2023. The obtained NDVI and LST results were compared and correlation analysis was performed. The highest values of LST were obtained in the year 2018. It was observed that the study area had more vegetation, especially in the southwest and northwest, according to NDVI values. It was observed that LST values demonstrated parallel results with the change in average temperature. For example, the average temperature increased in 2018, and decreased in 2023 and the same results were observed for the LST values. When the spatial-temporal maps were examined, it was observed that LST values were higher in regions where NDVI values were low, but a strong correlation between NDVI and LST was not observed during the study period. With this study, changes in vegetation and land surface temperature in Mus province can be examined on a regional scale and will be useful in taking necessary precautions.
