AB: Aerosol plays a central role in atmospheric processes, and understanding its interplay with atmospheric water is crucial for quantifying its indirect and direct climatic effects. This talk will give an overview of the impact of aerosol water (either liquid or adsorbed) on the ability of aerosol to nucleate cloud droplets and ice. We will also discuss the importance of aerosol phase and relative humidity history in controlling the mass partitioning of semivolatile compounds. Results taken from in-situ and laboratory experiments will illustrate the importance of knowing aerosol-water interactions and particle phase state.
