This is a general open session on all aspects of Aerosol Chemistry and Microphysics. Contributions from aerosol laboratory, field, remote sensing and model studies are all highly encouraged.

This year the session will have a focus on the role of water within aerosol chemistry and microphysics. Recently the role of water as a reactant, solvent and plasticizer within aerosols has garnered much attention, especially in the context of organic aerosol systems, which are typically thought of being of low hygroscopicity. Contributions investigating how water affects the chemistry and microphysics of aerosols and how this compares to both aqueous droplets and bulk liquids are especially invited.

The first solicited speaker for this session is Prof. Hartmut Hermann (TROPOS, Leipzig Institute for Tropospheric Research) who will give a talk on Tropospheric Multiphase Chemistry: Current Foci€, which will review laboratory investigations, recent field work and model developments. The second solicited talk will be given by Prof. Rainer Volkamer (University of Boulder, USA)€œNovel insights about salting-effects and reactivity of soluble molecules in aqueous aerosols€, which will discuss the Setschenow salting behavior of organics and the effect of anthropogenic triggers for the reactivity of multiphase reactions.
