Short summary

The detailed molecular composition of ambient fog and aerosol influenced by regional biomass burning and secondary processes was studied. Aerosol and aqueous-phase functionalization and oxidation were observed, leading to fog compositions that are more "SOA-like" than aerosols. The significance of the aqueous phase in transforming the molecular chemistry and contributing to secondary organic aerosol is demonstrated here.
