Overall forcing at the TOA is negative averaged over all aerosols, but significant atmospheric heating and a net positive TOA forcing is possible for aerosols with a strong black carbon component, and some of this will eventually be transmitted to the surface despite the reduction in surface insolation from the light scattering and absorptive properties of the aerosols.

The annual average is about 0.25 of the peak — but you expect as well that the reflected SW would not vary as much as you suggest albedo of oceans being influenced by «solar zenith angle, wind speed, transmission by atmospheric cloud / aerosol, and ocean chlorophyll concentration.»
