USE OF SATELLITE IMAGES FOR THE ESTIMATION OF THE EARTH SURFACE TEMPERATURE IN THE MUNICIPALITY HABANA DEL ESTE, HAVANA, CUBA.

Abstract

The use of satellite images has become, in recent decades, one of the most common ways to estimate the Earth's Surface Temperature (TST), one of them is through the use of modern Landsat family satellites. The purpose of this study is to evaluate the possibilities of using the inversion of the radiative transfer equation for the estimation of TST in the Municipality of Habana del Este, using images from Landsat-8 and 9 satellites. In this research, images were used of the platforms mentioned above and atmospheric parameters (τλ, L↓atmλ, L ↑atmλ) to obtain the TST in the work area through the radiative transfer equation. Then, the relationship that existed was evaluated, through regression analysis, between the TST values obtained and a set of field samples of ambient temperature near the ground, collected between September and November 2023. A good fit was obtained between the estimated and measured values, which are manifested in a linear correlation coefficient of 0.72 and a mean square error of 1.43°C. Based on this, a thematic map was prepared that reflects the TST of the work area for November 10, 2023.
