Assessment of diurnal change in land surface temperature of the Union Territory (UT) of Jammu and Kashmir, India

Land Surface Temperature refers back to the calculation of ground temperature that is made with extraordinary factors. Due to changes in the land surface temperature of the area, the climate and vegetation are also affected. The Normalized Difference Vegetation Index (NDVI) serves as an indicator of vegetation abundance to estimate the land surface temperature (LST) vegetation relationship. Landsat 7 ETM + and Landsat 8 OLI TIRS images for four years (2005, 2010, 2015, and 2020) are used to study the LST changes in the research area (Jammu & Kashmir). Correlations between NDVI and LST are calculated. Through the study, it is clear that the Normalized Difference Vegetation Index plays a major role in the calculation of land surface temperature. In this study, the change in the higher temperature noted in the year 2005 was 20 0 C, and in the year 2020, the highest temperature was 25 0 C. If we talk about the lower temperature, the change is 1 0 C. Both Jammu and Kashmir have semideciduous vegetation that includes subtropical pine forests.
