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 aerosols in the urban atmosphere. A large percentage of the world’s population lives in urban areas (e.g. Europe’s urban population = 74% in 2015), hence understanding the effect of aerosols upon humans and their activities is particularly important in these regions. Urban aerosols can have different aerosol microphysics and chemistry, compared to non-urban areas, because of distinct sources, aging mechanisms and loss processes. An invited talk will be given by Prof. Roy Harrison (University of Birmingham, UK).

There will also be a subsession investigating the phase partitioning properties of molecules and mixtures relevant to atmospheric aerosols. Drivers for such studies are often the development of mechanistic models that attempt to understand and model gas to particle partitioning of important chemical species at the molecular level. Processes include absorption, adsorption, reactive uptake, condensed/gaseous phase reactions, condensed/gas phase diffusion and non-ideality.
