SURFACE RADIATION BALANCE AND THE LAND USE IN THE AMAZON REGION

SUMMARY

The goal of this study is to verify the relationship between the change in land use and occupation and the balance of surface radiation in the Macapá Metropolitan Area (RMM), which is placed in the Legal Amazon Northeast, due to the fact of the fast urbanization of the area. The development of the urban areas causes changes on the cover and use of the soil which could have a direct effect on the surface energy balance that may result in atmospheric modification in a local, or even regional, scale. In order to verify the RMM urban development, were used images from LANDSAT TM and OLI/TIRS of five different periods. Therefore, through the supervised classification MAXVER, it was possible to verify an expansion of the build-up area, the class of soil that covers the urban sheet, between 1986 and 2015. The data collected showed the biggest thermal changes took place further from the city, due to changes in the use of the soil in the isolated region of the RMM, Since the expansion of the urban network of the RMM occurs in the SW and S directions, with emphasis on the Fazendinha district, which is located between the center of Macapá and the center of the city of Santana.
