The use of fossil fuels, deforestation and various industrial processes cause the accumulation of greenhouse gases in the atmosphere and a global temperature increase. This negatively affects both biodiversity and people's comfort of life. This global heat increase also changes the temperature of our world's outer crust. The temperature values of the outermost surface of the earth known as Land Surface Temperature (LYS) can be measured by many different methods. Remote sensing studies are widely used because of the most economical and rapid results among these methods. This study aims to reveal the long-term (29-year) YYS change of Mus province. YYS maps from 1990-2000-2005-2011-2019 were produced using Landsat 5 TM and Landsat 8 OLI satellite images. In the maps, LYS values were found to be lower in places where vegetation is dense. Although the YYS values of Mus province have increased and decreased compared to years, it can be said that there is an increasing temperature trend in general. In Mus province, the average temperature increased by approximately 0.3 °C each year.
