Noting here that data used to make figures in "Acidity and the multiphase chemistry of atmospheric aqueous particles and clouds" article can be found within the paper and associated supplement. This dataset is not publicly accessible because: Figure data are already embedded in the paper tables/supplement by authors external to the EPA. It can be accessed through the following means: The figure data are found within the paper tables and supplemental information (SI) and thus can be accessed by downloading the paper and SI. One may also contact co-authors, V. Faye McNeill (vfm2103@columbia.edu) and/or Hartmut Herrmann (herrmann@tropos.de) for additional information. Format: Data used for the figures are provided in the paper tables and supplement at the following link: https://doi.org/10.5194/acp-2021-58.

Oxidation of the monoterpene Δ3-carene (C10H16) is a potentially important and under-studied source of atmospheric secondary organic aerosol (SOA). We present chamber-based measurements of the speciated gas and particle phases during photochemical oxidation of Δ3-carene. We find evidence of highly oxidized organic molecules (HOM) in the gas phase and relatively low volatility SOA dominated by C7-C10 species. We then use computational methods to develop the first stages of a Δ3-carene photochemical oxidation mechanism and explain some of our measured compositions. We find that alkoxy bond scission of the cyclohexyl ring likely leads to efficient HOM formation, in line with previous studies. We also find a surprising role for the abstraction of primary hydrogens from methyl groups, which has been calculated to be rapid in the α-pinene system, and suggest more research is required to determine if this is more general to other systems and a feature of autoxidation. This work develops a more comprehensive view of Δ3-carene photochemical oxidation products via measurements and lays out a suggested mechanism of oxidation via computationally derived rate coefficients.
