dc.description.abstract
A weekly cycle in aerosol pollution and meteorological quantities is observed over Eu-rope. In the present study we exploit this effect to analyse aerosol-cloud-radiationinteractions. A weekly cycle is imposed on anthropogenic emissions in two generalcirculation models that include parameterizations of aerosol cycles and cloud micro-physics. It is found that the simulated weekly cycles in sulfur dioxide, sulfate, andaerosol optical depth in both models agree reasonably well with the observed onesindicating model skill in simulating the aerosol cycle. A distinct weekly cycle in clouddroplet number concentration is demonstrated in both observations and models. Forother variables, such as cloud liquid water path, cloud cover, top-of-the-atmosphere radiation fluxes, precipitation, and surface temperature, large variability and contradictoryresults between observations, model simulations, and model control simulations with-out a weekly cycle in emissions prevent us from reaching any firm conclusions aboutthe potential aerosol impact on meteorology or the realism of the modeled secondaerosol indirect effects.
