Short summary
We investigated the aqueous nitrate-mediated photooxidation of four green leaf volatiles (GLVs). The aqueous reaction medium conditions, dilute cloud/fog vs. concentrated aqueous aerosol conditions, governed the effects that pH, ionic strength, and sulfate have on the GLV degradation rates and aqueous secondary organic aerosol (aqSOA) mass yields. Most notably, reactions initiated by sulfate photolysis have significant effects in aqueous aerosols but not in cloud/fog droplets.
