%X We study the atmospheric transport of carbon monoxide from biomass burning that took place during the early months of 1998 in Roraima. Due the activity of the El Niño 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 CATT-BRAMS (Coupled Aerosol and Tracer Transport model to the 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 and validated with data collected during the LBA-CLAIRE-98 campaign. The flight 8 over Suriname on March 26, detected at high altitudes (> 9km) a layer of air mass with chemical composition characteristic of aged biomass burning smoke over a clean air column. The numerical simulation was able to reproduce the observed CO profile and could explain the main transport mechanisms involved.

%O The LBA-ECO Science Team Meeting for 2005 was held in at the Conference Center of the American Chamber of Commerce (AmCham) in São Paulo from November 10-12, immediately following the II Regional Conference on Global Change: South America, also held in São Paulo. The LBA Science Steering Committee also met in São Paulo shortly after this meeting on November 14-15.
