                         temperature and short-wave radiation balance derived from biomass 
                         burning in Rondonia State for 2000-2011 years, using RegCM4 for 
                         meteorological modeling. This model requires some input data such 
                         as land use and land cover maps (with and without burned areas) 
                         and physical parameters such as the surface albedo (separated in 
                         photosynthetic active radiation and in shortwave infrared 
                         reflectance), leaf area index and the fraction of vegetation 
                         cover. Thus, the land use and land cover maps were updated from 
                         MCD12A1 product of Moderate Resolution Imaging Spectroradiometer 
                         (MODIS) sensor. The MOD09 and MYD09 products of MODIS were 
                         utilized for the burned areas mapping, obtained from the Linear 
                         Spectral Mixture Model (SLMM), segmentation of shadow fraction 
                         images and manual editing. The surface albedo and the fraction of 
                         vegetation cover data were collected in the fieldwork with 
                         FieldSpec Pro equipment and leaf area index was obtained from 
                         MYD15A2 and MOD15A2 of MODIS products. The results indicated that 
                         the burned areas exhibit significant variability in Rondonia 
                         State, especially in 2005, 2010 and 2004 years, and these burnings 
                         occur in majority in areas that already have some type of use 
                         (areas of vegetation extraction, large animals livestock areas and 
                         diverse permanent crops). The albedo values showed a decrease of 
                         16\% with the occurrence of a fire, a factor that causes changes 
                         in short-wave radiation balance. These changes occasioned the 
                         elevation of soil temperature, which can reach maximums values of 
                         10 degrees C per day, resulting in significant changes in 
                         different climatic variables that may alter the local and regional 
                         climate.",
