		<abstract>Wildfires plays a fundamental intervention in global biogeochemical cycle, by the chemical reaction that occurs in the combustion process, the organic compounds present in vegetation returns to the atmosphere and soil in a cyclical behavior. It is estimated that the first fires occurred at the end of the Silurian period about 405 million years, mainly caused by lightning and spontaneous combustion. In Brazil, temporal and spatial variability in land-use and land-cover due to agricultural land clearing, grassland management and deforestation of the Amazon tropical rainforest leads to variations in anthropogenic biomass burning. This issue affects the environment, altering the atmospheric and surface radiation balance, besides the hydrological cycles. Therefore, the main objective of this work is to develop a method to estimate the instantaneous fire size to Brazil through Thematic Mapper (TM) aboard of Landsat 5 and Enhanced Thematic Mapper Plus (ETM+) aboard of Landsat 7. To create the Brazilian fire size climatology, 79 path/row Landsat scenes were randomly sampled by biome and fire Radiative power distribution. The results indicate that average fire size in grasslands and pasture has 10.000m² and reaches a maximum of 30.000m². Also, forested areas and herbaceous/shrubby vegetation presented fire size of 4000m² and 7500m², respectively.</abstract>
