Surface temperature (ST) has been historically recorded in meteorological stations ai specific geographic locations. That data has been used later as a proxy for larger areas, despite knowing that ST changes accordingly to local factors, such as topography and latitude. More recently, small-scale variations on ST have been estimated by satellite images that reveal terrestrial ST. This study aimed to estimate ST from a Landsat 5TM image of the northeastern area of Brunswick Peninsula, using standard algorithms for each pixel on the image. To test the method we compared the values estimated with those recorded at the Jorge Schythe meteorological station from the air temperature. We successfully applied here the method of climate variable calculation from satellite images and thus obtained a cartography showing the variability ST at Brunswick Peninsula.
