Aerosols are a key player in atmospheric research: they influence the radiation budget via the direct aerosol effects, impact cloud properties via the indirect effect. Additionally they can alter the chemical composition of both gas and aerosol phase. To represent those aspects in large scale models, it is necessary to find suitable simplified parameterisations to describe the processes with sufficient interactions with the other components of the atmospheric system. In the atmospheric chemistry general circulation model EMAC (ECHAM5-MESSy Atmospheric Chemistry), we have implemented several submodels to describe aerosol processes and their fate in the atmosphere; the description can vary in detail suitable to the task under investigation. Aspects presented in the presentation will cover the chemical and microphysical properties of the aerosol, its transport and links to its direct and indirect effects.
