Resumo
The occurrence of vegetation is an important factor regarding the maintainance of natural biogeochemical
processes. In the Cerrado, the conversion of the vegetative cover into crop fi elds and areas of cultivated
pastures has induced severe modifi cations in biophysical variables such as land surface temperatures, highly
sensitive to land cover / land use changes. Thus, and aiming at a more thorough understanding of the
land conversion impacts on the Cerrado biophysical variables, in this study we assessed, through orbital
data (MOD 11 product - Land Surface Temperature), the correlation between land occupation and thermal
variability, considering 2003 imagery obtained at the beginning and end of the dry season. Data analysis
showed signifi cant differences in surface temperature between natural and converted classes and revealed
the spatial patterns and dependency of this variable in relation to seasonality.
