The principal objective of this paper is to analyze the changes of air temperature in the city of Barra do Garças - MT, using the thermal images of the landsat-8 satellite. The procedures for acquiring free digital orbital images were obtained from the Landsat Satellite - 8 OLI sensor (Operational Land Imager) at the American Geological Survey Service (USGS), considering orbit 224, point 71, dated 06/24/2016 to 09/02/2018, central time 10:30 am, band: 10 with spatial resolution of 30 meters and thermal band 10 infrared (10.6 - 11.19 ?m - micrometer), in order to observe the temperature behavior in the urban area of Barra do Garças. The terrestrial daily temperature data were acquired from the Weather Database for Teaching and Research BDMEP / INMET, referring to the weather station of Aragarças - GO. From the analysis observed through thermal images for the affore mentioned period, it was seen that the month of September registered the highest values, in the year of 2017, the peak was 48ºC, in 2016 it was 44ºC and in 2018 it was 38ºC. It was found that, throughout this analysis, the highest temperatures occurred in the neighborhoods that are in the lowest places of the urban site. Therefore, the western, southern and extreme eastern portions of the city showed higher temperatures. ; Este trabajo tuvo como objetivo principal analizar las variaciones de las temperaturas del aire em la ciudad de Barra do Garças – MT, desde la utilización de la imagen térmica del satélite Landsat-8.
