• The aerosol direct radiative effect (DRE) over Europe is computed using the deterministic spectral radiative transfer model FORTH and aerosol data from the Chemical Transport Model PMCAMx. Chemically and size resolved aerosol concentration predictions by PMCAMx, are forwarded to the Mie scattering code AtmOptC, in order to calculate the key aerosol optical properties required for the derivation of the DRE (scattering and absorption coefficients, single scattering albedo and asymmetry parameter). The estimation of the DRE (at the Earth’s surface, inside the atmospheric column and at the top of the atmosphere—TOA) is performed on a high spatial and temporal resolution (36 km × 36 km, hourly) during June and July of 2012, over the European region. The aerosol direct radiative effect exhibits significant hourly and daily variability associated with wildfires and synoptic conditions. Maximum DRE values are predicted over urban/industrial centers and biomass-burning areas with expectedly large optical depths. The two-month DRE average shows a cooling effect at the TOA and surface (local values down to −15 and −35 W/m2, respectively) and a warming effect in the atmospheric column (columnar value up to 25 W/m2, locally).
