Resumo

The replacement of natural forests to monoculture can cause changes in local and regional climate due to changes in net radiation and energy exchanges between the surface and the atmosphere. Thus, the objective of this study was to evaluate changes in biophysical indices such as Normalized Difference Vegetation Index (NDVI), albedo, temperature and net radiation of the surface due to the change of land cover in native Cerrado area in Campo Novo do Parecis, Mato Grosso State. We obtained Landsat 5 TM images to calculate the biophysical indices in protected and deforested areas. The NDVI of the protected area was 72% higher, the surface albedo was 56.1% lower and the surface temperature was 39.2% lower than in the deforested area. Thus, the balance of daily radiation in the protected was 6.6% higher than in the deforested area, which showed that conversion of native Cerrado area modifies the net radiation exchange between the surface and the atmosphere.
