Sensoriamento Remoto Aplicado ao Mapeamento da Temperatura de Superfície Terrestre: Uma análise espaço-temporal de Nova Rosalândia – TO

The land surface temperature is a very important climatic variable to understand the processes that exists in the environment. In this way, this study aims to evaluate the surface temperature variation in the municipality of Nova Rosalândia TO (Cerrado biome) associated with the possible changes that occurs in land use during the period from 2005 to 2018, by the use of images from the Landsat satellites. This study indicates that during these years, there was an increase in surface temperature in the municipality of Nova Rosalândia, where 2018 was the year with the higher temperatures, registering surface temperature values up to 41°C. This fact is also evidenced by the increase of minimum (1.9°C), average (2.7°C) and maximum (2.8°C) temperatures in the municipality. In addition, it is observed that the variations on the surface temperature values have a strong correlation with the changes that occur in land use in the municipality from 2005 to 2018. It should be noted that changes in land use were caused mainly by the agribusiness’s expansion in the municipality, which contributed to the increase in surface temperature on the region. The remains of vegetation presents a mitigating factor in temperatures. Therefore, the results expand the discussion around the Brazilian Journal of Development Braz.
