Different roles of water in secondary organic aerosol formation from toluene and isoprene
Short Summary: In this work, the opposite effects of relative humidity (RH) on secondary organic aerosol (SOA) formation from toluene and isoprene were observed and have been well explained in terms of various experimental data and model simulations. The increase of SOA from toluene under humid conditions is mainly contributed by aqueous reactions of water soluble products, whereas SOA formation from isoprene-NO2 irradiations is controlled by stable Criegee intermediates that are greatly influenced by water.
