Abstract Environmental chamber experiments were conducted studying SOA formation and growth from ozonolysis of alpha-pinene, beta-pinene, delta-carene, and limonene under varying concentrations of NO$_2. Qualitatively different NO$_2 dependences are observed for the different biogenic precursors. Analysis of SOA growth kinetics and aerosol chemical composition, as well as chemical kinetics box modeling, are used to identify mechanistic reasons for the observed behavior.
