Short summary

Identifying the chemical pathways of condensable products such as carboxylic acids is essential for predicting SOA formation. This identification is inherently difficult, as such products reside in both the gas and particulate phases. We measured acids, produced from atmospheric oxidation of limonene, in both phases and scrutinised the mechanistic understanding of their formation. The mechanisms explain nearly 75 % of the gas-phase signal at the lowest concentration (8.4 ppb, 23 % acid yield).
