Fig. 3: Relationship between the highly oxygenated organic molecules (HOM) yields and the product of p-HOM-RO2 yield (γp-HOM-RO2) and oxidation fraction of p-HOM-RO2 (OFp-HOM-RO2).
From: A mechanistic understanding of the varying yields of highly oxygenated organic molecules
Square, Down Triangle, Rhombus, Left Triangle, and Circle denote data from CLOUD experiments of varying NO (Exp 1), pure NO2 (Exp 2), constant NO/NO2 with 1200 ppt monoterpene (Exp 3), constant NO/NO2 with 300 ppt monoterpene (Exp 4) and NOx-free conditions (Exp 5), respectively. Note that the monoterpene used in the NOx-involved experiments was a mixture of α-pinene and Δ−3-carene with a volume mixing ratio of 2:1. The monoterpene used in the NOx-free experiment was pure α-pinene. The propagated error of the HOM yields varies within 10 % among different experiments. A significant monotonic correlation is observed, with Kendall’s tau τ = 0.747 (p < 0.01), accounting for small sample size and potential non-linearity.
