Parâmetros Biofísicos Aplicados no Parque Nacional da Serra das Confusões, Piauí-Brasil

Abstract The objective of this work is to evaluate the biophysical parameters, rainfall and surface temperature in the vegetation conditions, in the Serra das Confusões National Park (SCNP), Piau-NEB. With the aid of the images obtained from the satellite Landsat 8 it was possible to calculate the Normalizes Difference Vegetation Index (NDVI) and the surface temperature (Ts). The SCNP rainfall presented a well-defined seasonality, dry and rainy seasons, which play a crucial role in the vegetation conditions of the SCNP. The NDVI class (> 0.693) had the greatest reduction o the coverage area around 72.7%, while the classes (0.347-0.433) and (0.433-0.52) had an increase of 34.7% and 31, 8%, respectively. In addition, it was clear that vegetation condition influenced the Ts of the region.
