Aerosol particles are key components of the earth system important in radiative balance, human health, and other areas of key societal concern. Understanding their formation, evolution and impacts relies on developments from multiple disciplines covering both experimental laboratory work, field studies and numerical modelling. In this general session all topics of Aerosol Chemistry and Physics are covered. Contributions from aerosol laboratory, field, remote sensing and model studies are all highly encouraged.
As in previous years, this year the session will dedicate some of its time to focus on a hot topic which this year is aerosol surface phenomena. Aerosol surface characteristics and heterogeneous reactions on aerosol surfaces impact they formation and atmospheric lifetime, and are also associated with adverse health effects. In addition, processes in aqueous aerosol surfaces are shown to significantly affect the cloud droplet activation. Despite of potentially important role of aerosol surfaces in atmospheric process, there are still very limited selection of methods that can be applied to study the surface characteristics and processes. With this in mind, aside from general submissions on aerosol research, we encourage contributions from work within the broad focus of aerosol surface phenomena. These might include work on:
* Molecular scale investigations, from single component to complex mixtures
* Evidence from laboratory and field studies
* New experimental capabilities
* New modelling capabilities
* Impact studies
