Aerosol particle formation studies in the industrial region of Vienna

Description

Aerosol nanoparticle formation from precursor gases is frequently oberved in the atmosphere and is thought to impact regional scale air pollution as well as global scale cloud properties.
Particle formation mechanisms usually involve sulfuric acid vapor, however, lately the nucleation potential of highly oxygenated organic compounds even in the absence of sulfuric acid has been demonstrated. Nucleating organic compounds may be of biogenic or anthropogenic origin. Understanding a potential anthropogenic fingerprint in new particle formation would be of significant societal relevance in the context of urban air pollution.
In this talk data on nanoparticle formation from a field study in suburban Vienna will be presented. The site is heavily influenced from anthropogenic activities due to the nearby oil refinery and the Vienna International Airport. Size distribution measurements taken at different locations indicate new particle formation to happen on a regional scale over the larger Viennese area.
