Does surface solar irradiance affect atmospheric aerosol attenuation?

We use surface solar irradiance from the NASA CERES-SYN1deg dataset from 2003 to 2014, which provides both all-sky (both clouds and aerosols are included) and all-sky-no-aerosol (only clouds are included without aerosols) scenarios. The effect of atmospheric aerosol attenuation is calculated by taking the difference between the two scenarios.
