Análise das áreas queimadas e das emissões dos gases do efeito estufa no Parque Estadual da Serra do Tabuleiro – Santa Catarina

Abstract

The main goals of the present work are the analysis of the biomass burning and the assessment of greenhouses gases emissions released into atmosphere in Serra do Tabuleiro State Park located in the state of Santa Catarina (SC). In this article, CCD sensor on China-Brazil Earth-Resources Satellite (CBERS) 2 and CBERS 2B platforms and Thematic Mapper (TM) sensor on Landsat 5 platform were used to extract the burned area. Through Intergovernmental Panel on Climate Change (IPCC) methodology, were found in 8 years (2001 to 2008) a amount of 1273 soccer fields were exposed to burn, releasing into atmosphere approximately 13.000 t of carbon dioxide (CO2), 525 t of carbon monoxide (CO), 20 t of methane (CH4), 7 t of nitrous oxide (N2O) and 250 t of nitric oxide (NO) and nitrogen dioxide (NO2). Moreover, the result shows a reduction of 83%, 50% and 80% in albedo, visible and infrared solar reflectance values in the burnt areas.
