                         observed in the Amazon and Central Brazilian atmosphere during the 
                         dry season is associated with intense anthropogenic biomass 
                         burning activity (vegetation fires). In addition to aerosol 
                         particles (PM), biomass burning produces water vapor and carbon 
                         dioxide, and is a major source of other compounds such as carbon 
                         monoxide (CO), volatile organic compounds, nitrogen oxides 
                         (NOx=NO+NO2), and organic halogen compounds. In the presence of 
                         abundant solar radiation and high concentrations of NOx, the 
                         oxidation of CO and hydrocarbons is followed by ozone (O3) 
                         formation. The high levels of O3 and PM induce several respiratory 
                         problems on the affect populated areas. PM has impact on weather 
                         modification by changing the energy budgets of the surface and 
                         troposphere, as well as the microphysical behavior of clouds, and 
                         consequently also their dynamics and precipitation efficiency. In 
                         this paper we describe a real time forecast of pyrogenic products 
                         over South America by using the Coupled Chemistry-Aerosol-Tracer 
                         Transport model to the Brazilian developments on the Regional 
                         Atmospheric Modeling System (CCATT-BRAMS). CCATT-BRAMS is an 
                         on-line transport model fully consistent with the simulated 
                         atmospheric dynamics and includes kinetic and photochemical 
                         reactions. The sub-grid transport parameterizations include 
                         diffusion in PBL, shallow and deep convection and plume rise for 
                         biomass burning emissions. The atmospheric model has a complex and 
                         state-of-art set of parameterizations to simulate 
                         surface-atmosphere exchanges, boundary layer development, cloud 
                         microphysics, radiative transfer, cumulus convection. Photolysis 
                         rates can either be used from LUT or calculated on-line using 
                         FAST-TUV which is fully coupled with the aerosol and microphysics 
                         modules. The system may be virtually configured with any desired 
                         chemical mechanism using a modified version of SPACK (Simplified 
                         Preprocessor for Atmospheric Chemical Kinetics). For initial and 
                         boundary conditions, the system is able to be nudged by large 
                         scale atmospheric-chemistry models analysis using a Newtonian 
                         relaxation scheme. Currently the system is able to assimilate 
                         MOCAGE (Meteo-France global chemistry model) fields. Emissions are 
                         prescribed through a pre-processor for anthropogenic, biogenic, 
                         biomass burning, etc, using a set of published methodologies or 
                         inventories. Fire emissions are updated on near real time and are 
                         spatially and temporally distributed according to the fire counts 
                         locations obtained by remote sensing (AVHRR, MODIS and GOES-12). 
                         An operational system has been implemented which produces daily 
                         72-hours numerical forecast of CO, O3, PM2.5 and NOx in addition 
                         to traditional meteorological fields. We present and discuss some 
                         important events of air pollution associated to vegetation fires 
                         captured by this operational system for the burning season of 
                         July-October 2009 over South America.",
