abstract = "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 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
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.",
