Abstract

http://dx.doi.org/ 10.5902/2179460X16230

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.
