%X The South American continent presents an extraordinary diversity of land use, vegetation and soil coverage. One area where this diversity is exemplified is the Rondonia state of SW Amazonia (Figure 1). As a consequence of the landscape variety, trace gases and aerosol emission sources are highly variable in space and time. Not only is the actual spatial emission pattern very complex but the time changes observed in the last decade have been immense. The annual deforestation area, just in the Brazilian Amazonia, ranged between 11,030 and 27,362 km2 in the last 18 years for a total of 333,037 km2 of deforestation according to the satellite monitoring program of INPE (The Brazilian National Institute for Space Research; http://www.obt.inpe. br/prodes). Several hundred of thousands of vegetation fires are regularly detected in South America during the austral winter everyyear. This is driven by the fact that biomass burning is an agricultural practice often used for expanding the crop and livestock land. The fire activity affects mainly the forest and savanna biomes but it is also extensively used for the renewal of pasture and of the Amazon (Cordova et al., 2004) or it can be transported southward affecting highly urbanized and populated areas (Freitas et al., 2005). Recent studies point to the strong direct and indirect effect of the smoke aerosol on radiative balance and precipitation patterns (Andreae et al., 2004, Koren et al., 2004) and on photochemistry (Albuquerque et al., 2005).
