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 volatility. Despite significant advances in experimental techniques, it is still thought that an incomplete understanding of factors that dictate gas-particle partitioning remains one of the major uncertainties in predicting atmospheric aerosol concentrations, composition, life-time and subsequent impacts. With this in mind, aside from general submissions on aerosol research, we encourage contributions from work within the broad focus of aerosol volatility. These might include work on:
• New process pathway identification
• Molecular scale investigations, from single component to complex mixtures
• Evidence from field studies
• New experimental capabilities
• New modelling capabilities
• Impact studies
