Atmospheric Oxidation Capacity Constraints: Laboratory Investigations, Field and Remote Sensing Observations, and Modeling Studies
Session ID#: 72614
Session Description:
This session focuses on the investigation of gas phase and multiphase atmospheric oxidation of VOCs, initiated by various oxidizing agents, including the OH, O3, NO3 and Cl. Observational constraints of these oxidizing agents are sparse, particularly for OH, the atmosphere's primary oxidant. We solicit presentations that highlight novel studies using laboratory kinetics, in situ and satellite observations and models that provide insight into the temporal and spatial distribution of these oxidants, their constraints and the factors that control their distributions from local to global scales. Satellite data have the unique advantage of spatial coverage; so space-based observational constraints on OH and the factors that control OH are particularly encouraged. Additional processes of interest include oxidant impacts on the formation of secondary products (e.g., O3, PAN and SOA). Modeling studies are encouraged; particularly those elucidating new chemical mechanisms, investigating the impact of newly identified radical sources, and/or their uncertainties.
