                         Roraima. Due the activity of the El Niņo atmospheric phenomenon, 
                         the vegetation fires occurred with a remarkable intensity. We 
                         focus on the role of deep convective systems on the 3d CO 
                         redistribution using the Eulerian approach for CO mixing ratio 
                         determination. The simulation is carried out using the system

                         Brazilian developments on the Regional Atmospheric Modeling 
                         System). In this method, the mass conservation equation is solved 
                         for carbon monoxide (CO) in-line with the atmospheric model 
                         equations. Source emissions of gases associated with biomass 
                         burning activities in are parameterized and introduced in the 
                         model. The daily burned area estimate is obtained through a 
                         normalization of the total burned area using the TOMS Aerosol 
                         Index. We also used a convective parameterization with training 
                         capability in order to improve the representation of the involving 
                         deep convective systems in the model. Model results are compared
