Fig. 1: The yields of Highly oxygenated molecules (HOM) calculated using different methods in different experiments.
From: A mechanistic understanding of the varying yields of highly oxygenated organic molecules
a The common method as the dependence of HOM formation rates (PHOM) on monoterpene oxidation rate (MTreact), and (b) the new method as the dependence of the HOM yields on α-pinene oxidation rate, in which the HOM yields are calculated as the ratio of the HOM production rate over the α-pinene oxidation rate for each steady-state stage. Symbol types denote data from Ehn et al.26, Jokinen et al.33, Kirkby et al.17, Simon et al.20, and another α-pinene oxidation experiments conducted in CLOUD chamber. HOM are defined by NO ≥ 7 for this study, while for previous experiments, the HOM definitions follow those used in the original references. The data points are color-coded by experimental temperatures. Details about these experiments are listed in Supplementary Table 1. The grey dashed lines in (a) show different HOM yields and the lines in (b) are plotted to guide the eyes.
