Dear authors,

Thank you for the detailed response to reviewers’ comments. I think you have addressed their comments sufficiently. I just have a few very minor technical notes. The manuscript will be accepted for publication in ACP once these are addressed.

(the line numbers correspond to those in the revised manuscript)

1. Line 114. It would also be appropriate to cite Bean and Hildebrandt Ruiz (ACP, 2016), Boyd et al. (ACP, 2015), and Boyd et al. (ES&T, 2017).

2. Line 116. Delete citation of Boyd et al. in this sentence, as this work does not discuss photochemical aging.

3. Line 227. Also isoprene oxidation by NO3? This was discussed in the next paragraph.

4. Line 287. A few recent laboratory studies have investigated the effects of RO2 fates on aerosol formation from nitrate radical oxidation, representative of different atmospheric environments (Ng et al., ACP, 2008; Boyd et al., ACP, 2015; Schwantes et al., J. Phys. Chem. A, 2015). More studies are needed definitely, especially regarding the role of RO2 autoxidation in nitrate radical oxidation chemistry.

5. Line 306. I think the "hydro full" case does not include the hydrolysis of TERPN2 (monoterpene nitrates from NO3 oxidation)? It would be useful to state this here explicitly for clarity.

Best,
Sally
