AS3.12

The gas-phase oxidation of organic compounds leads to the formation of less volatile organic compounds that may condense on aerosol surfaces. One key aspect of the transformation of organic species is the fate of organic peroxy radicals that are formed after the initial radical attack. This session aims for contributions connecting the gas-phase oxidation of organic compounds with the formation of secondary organic aerosol. Oxidation agents can be the hydroxyl radical, ozone or the nitrate radical. We invite contributions on the investigation of the gas-phase chemistry leading to secondary organic aerosol or on the investigation of aerosol properties as a consequence of the oxidation process. Contributions can include the development and test of mechanisms describing the chemical transformation of organic compounds in laboratory and in experiments in simulation chambers as well as insights from field studies.
