Effect of temperature and relative humidity on the mass fraction of particle-phase components (defined as the ratio of PILS + UPLC/ESI-Q-ToFMS characterized mass concentration of individual species to the SMPS measured total particulate organic mass) when >99% α-pinene is reacted (predominantly with O3). Corresponding temporal profiles of these compounds are given in SI Appendix, Figs. S6 and S7.
