Abstract
The Amazon region has a unique tropical ecosystem that still preserves much of its native forest, however, has undergone extensive changes due to the constant presence of fire in the region. The chemical module of the atmospheric model WRF (WRF/CHEM – Weather Reaserch Forecasting/CHEMistry), allowed analysis of the concentration and dispersion of the trace gas Carbon Monoxide (CO), arising from burning source detected operationally in the National Institute for Space Research (INPE), by AVHRR sensors of the NOAA-15, NOAA16, NOAA-17, NOAA-18 and NOAA-19 polar satellites; images of MODIS sensor on NASA’s polar satellites TERRA and AQUA, and the images of the geostationary satellites GOES-12 and MSG-2, on August 19, 2010. To evaluate the dispersion wind direction and was used at 10 meters high, in order to estimate the destination of the gas plume emitted by the forest fire, is also an analysis of the transport of atmospheric trace gas column through remote sensing with instrument information AIRS (Atmospheric Infrared Sounder) aboard the AQUA satellite. It was seen CO can affect local air quality by taking high concentrations within a few kilometers of the emission source ( approximately 2000 ppbv), but with the dispersion of the gas due to the wind, it is possible to see concentrations close to 500 ppbv at least 300 km from the emission source, with transport of pollutant reaching other countries of South America.
