The atmospheric oxidation of organic compounds is progressive and leads to the formation of a myriad of secondary organic compounds. These secondary organic compounds (SOC) can be hydrosoluble and react in the atmospheric aqueous phase. The scientific community is currently interested in the environmental impact of the atmospheric organic matter aqueous phase reactivity. For example, recent studies show that these modifications could increase the secondary organic aerosol (SOA) production. In order to explore effects of the aqueous reactivity, this work consists of a detailed modeling study of the SOC dissolution and their aqueous oxidation. The modeling is based on the extension of the explicit chemical schemes generator GECKO-A (Generator...
