The atmospheric aerosols are affected by several atmospheric processes as nucleation, condensation, coagulation, cloud formation and dry/wet deposition. Different sources, anthropogenic and natural, produce quite different particles and precursors giving particles of different siza and chemistry, in turn interacting and mixing with the background aerosol. Measurements to establish the basic understanding of concentrations and variation in size and chemistry in different environments and phases of the evolution of the atmospheric aerosol are absolutely necessary to develop and test models. The models are necessary in getting a full understanding of how the antropogenic aerosol affect air quality and climate. In this presentation I will discuss which parameters that are possible and which that are necessary to mesure to improve our understanding of how atmospheric particle affect aur health and climate.
