Short summary

A series of chamber experiments was performed to probe the individual and common effects of NH₃ and NO_x on toluene secondary organic aerosol (SOA) formation through OH photooxidation. The synergetic effects of NH₃ and NO_x on the toluene SOA concentration and optical absorption were observed. The higher-volatility products formed in the presence of NO_x could precipitate into the particle phase when NH₃ was added. The formation pathways of N-containing OAs through NO_x or NH₃ are also discussed.
