Abstract

Through the aerial measurements of trace gases from biomass burning and from a numerical model developed in a doctoral thesis, we verified the existence of high concentrations of CO2 in regions where there is no burning (brought in by transport). In this work we aim to measure these concentrations in situ. We will install monitoring stations for trace gases from biomass burning in the cities of Campo Grande, Mato Grosso do Sul and Apucarana, Paraná, where we will take measurements, on the surface of carbon monoxide, ozone and carbon dioxide (dry and wet season), and will also undertake the launching of ozone probes to determine the ozone profiles in both cities. With this we hope to prove the existence of high concentrations of carbono monoxide in regions with little burning. (AU)
