AB: Aerosol introduces one of the larger uncertainties in climate modeling. This led to new efforts in the global modeling community to represent aerosol properties and processes in more detail (including interactions with chemistry and clouds). With a distinction among different aerosol types, new untested assumptions were made and need to be evaluated, preferably to measurements. The AeroCom project http://nansen.ipsl.jussieu.fr/AEROCOM seeks to document differences of aerosol component modules (of global models) and to assemble useful data-sets for model evaluations. AeroCom's overall goals are the identification of weak components in aerosol modeling and an assessment of current uncertainties with respect to simulated aerosol optical properties and the associated radiative forcing. AeroCom participation is still open to any aerosol-component global modeling group and any measurement-groups, which measure properties relevant to simulated aerosol properties and aerosol parameterizations. First results on unified data-sets and on model performance will be presented.
