Arid regions are characterized by fluctuating vegetation cover and elevated temperatures, presenting unique challenges for ecological and climatic studies. This research investigates the relationship between limited vegetation cover and temperature variations. Consequently, it is imperative to consider vegetation cover when analysing any temperature-related indices. To this end, we selected the Soil-Adjusted Vegetation Index (SAVI) as our primary focus, as the Normalized Difference Vegetation Index (NDVI) proved inadequate for accurately assessing vegetation cover in these environments. This study aims to ascertain the extent to which sparse and less verdant plant life influences surface temperature. Furthermore, we explore the potential of utilizing vegetation fraction as a criterion for temperature calculations in arid landscapes.
