Fig. 3: Model simulated non-linear dependence of the yields of highly oxygenated organic molecules (HOM) on NO₂ and NO at 278 K.

(a) total HOM, (b) CHO-HOM, and (c) CHON-HOM with 1200 pptv monoterpene. O₃ concentrations are constrained at 40 ppbv at each experiment. The contour lines indicate the corresponding HOM yields.
