The impact of aerosol-radiation feedback on meteorology and subsequent changes in pollutant distributions over Europe and the North Atlantic were investigated with WRF/Chem. The case studies for two summer months show that the direct effect of aerosol particles on solar radiation is dominated by semi-direct effects that are developing after a few days. Strong deviations from the baseline case, which does not include any feedback, were found for the global radiation over the North Atlantic and Northern Europe when the indirect aerosol radiative effect is considered.
