ESTUDIO DE LA ISLA DE CALOR URBANA DE LA CIUDAD DE SEVILLA MEDIANTE LA UTILIZACIÓN DE DATOS SATELITALES

Abstract

Under certain conditions, the heat from solar radiation and different urban activities can make city temperatures rise in certain areas, simply because of the way in which a city is structured. This effect is known as the urban heat island (UHI). This article provides the basis for future investigation focused on the relationship of land surface temperature (LST) with social-ecological variables, namely land use/land cover (LULC), vegetation index, impervious surface index, population index, fossil-fuel CO2 emissions, etc. During the progress of the investigation will be determined the correlation between mean LST and the rapid urbanization of the area. The formation and effects of UHI, including possible mitigation and adaptation measures, should be considered in the landscape and urban planning process for the future development of the city. Landsat data captured in 1987, 2002 and 2017 of Sevilla city were used to facilitate the analysis.
