Sumatra Land Surface Temperature Increase

Abstract

Climate change in Sumatra island is likely a result of widespread land-use changes by the plantation industry. This study aims to investigate trends in land surface temperatures in Sumatra island. Land surface temperatures from 20012020 were downloaded from the National Aeronautics and Space Administration moderate resolution imaging spectroradiometer Terra satellite and divided into 5 regions and 45 sub-regions spread equally across the island. The statistical method that used to analyzed the data was cubic spline and multiple regression. The seasonal pattern and variation in the land surface temperature were examined using a cubic spline method and the seasonally adjusted land surface temperature was analyzed using a multiple regression model. On average, the land surface temperature on Sumatra island significantly increased over the ten years by 0.076C with a 95% confidence interval of [0.010, 0.141]C.
