The SMOCC (Smoke Aerosols, Clouds, Rainfall and Climate: Aerosols from Biomass Burning Perturb Global and Regional Climate) study investigates the connection between large-scale aerosol emission due to biomass burning in tropical regions and potential climatic implications. As part of this project, tropospheric airborne measurements (between 0 and 5km altitude) of trace gases and aerosol particles were performed over the Amazon basin. The measurement period from September to October 2002 marks the transition period from dry to wet season. We will present results of these measurements with particular emphasis on particle number (CN), cloud condensation nuclei (CCN), CO, and CO2 concentrations. From these measurements, we have derived emission ratios and emission factors for aerosol particles and trace gases from deforestation and agricultural maintenance fires in southern Amazonia, which are important for determining the effects on the regional scale and on the global scale due to export of longer-lived substances.
