Orals

AS3.16

This is a general open session on all aspects of gas phase chemistry. The focus of this year will be on processes affecting the oxidation capacity of the atmosphere, particularly perturbations to HOx and NOx levels in the troposphere. Field measurements, laboratory and theoretical studies which do not fit into one of the other special sessions are welcome.
