Joint effort for AQMEII2 with common grid and input permits analysis of feedback effects on meteorology For the applied horizontal resolution, the impact of aerosol feedbacks on pollutant distributions was frequently smaller than the effect of the choice of the chemistry mechanism and aerosol module, and microphysics scheme.  No ‘best’ setup Differences depend on the parameters of the ‘base case’and consiered region (here, inclusion of indirect effect can reduce/enhance precipitation)  Complete analysis of the indirect effect may require simultionswith higher resolution
