Thank you for addressing the reviewers’ comments. There are a few more minor things that can be fixed before the final publication, for example:

P1, L11: is largely unknown -> are largely unknown

P1, L13-14: use kOH instead of k4 and kO3 instead of k6 in the abstract

P1, L20: e.g. by biomass burning -> for example, in presence of biomass burning

P2, L3: (Huber et al., 2007), is emitted -> (Huber et al., 2007). It is emitted

P2, L10: of carbon suboxide -> of carbon suboxide in more detail

P2, L19: in a similar manner to described previously -> as described previously

P3, L30: search for all instances of m/z and italicize the ones that are not italicized already

P3, L31: mass resolution -> mass resolving power

P4, L4: e.g. 1 hour -> e.g., 1 hour (also search for other instances of “e.g.” which should be surrounded by commas)

P5, L8: i.e. -> i.e., [also search for other instances of “i.e.” which should be surrounded by commas]

P5, L12: covers -> covered [there are a few other issues with consistency of verb tenses in this section]

P6, L9: Boyles law -> ideal gas law [Boyles law is something else]

P9, L23: Is the statement that INT8 has a fairly mobile hydrogen atom a guess or based on calculations? It is not clear from the text.

P10, L12: concentrations were -> partial pressure was

P11, L20: There is no previous experimental data -> There are no previous experimental data

P12, L29: acid -> acidic

P15: Figures 14 appears here twice and also appears again on page 32. Please fix.

All formulas: did not display correctly in the PDF but hopefully ACP formatting will fix that

All figures some of the figures appear to have low resolution – generating images with higher dpi is recommended for the final publication

Figure 1: figure background color should be white
