Introduction
The aerosol climatology was derived from the CAMS interim Reanalysis and its control run (Flemming et al. 2017) as described in Bozzo et al. (2019). The data set is based on the modelled aerosol mixing ratios of the control run, which were scaled to match the Aerosol Optical Depth (AOD) analyses of the CAMS interim Reanalysis (Data assimilation of MODIS AOD). It contains monthly mean 3D mass mixing ratios of desert dust (3 size bins), seas salt (3 size bins), organic matter, black carbon and sulphate as represented by the IFS-AER aerosol scheme (Remy et al. 2019) .

The file aerosol_cams_ifs_optics.nc provides the optical parameters needed for the implementation of the radiative effect of the CAMS aerosol species in the ECMWF radiation scheme. The file also provides the optical properties for a set of 20 individual wavelengths covering the visible and near-infrared spectral range.
