Dear authors,

Thank you for your thoughtful responses to reviewer comments. It appears that you have adequately dealt with the concerns raised and I will be happy to accept your paper for publication with some minor edits to help clarify a few of your additions to the text.

Specifically:
1. In response to reviewer 1, in the paragraph that starts with "Figure 5" you have a sentence 2/3 of the way through the paragraph that starts with "However, the latter in the EMAC model..." I don't know what you mean by the latter since the preceding sentence doesn't give two kinds of anything. I imagine you are talking about either OH or the methane lifetime but I would just say that explicitly rather than "the latter".

2. In response to the comment about grid resolution, I don't think I follow your logic for why higher resolution might reverse the effects of aromatics on ozone. I understand the previously published effects for NOx because ozone production is very non-linear in NOx so an intense plume behaves quite differently than a dilute one. But ozone production at a given NOx level will always increase with increasing VOC so I don't really understand how grid resolution could invert the response you show. For example, in the higher resolution case, for coemitted NOx and aromatics, then NOx-HOx interactions will, as you say, generate more HNO3 and less O3 than in the lower resolution case. But the aromatics will simply survive longer since near-field OH is being consumed by reaction with NOx so then they will disperse farther and the effect of aromatics might actually be more similar between the two resolutions than is the case for NOx. I may not be expressing my confusion clearly but I think it would be better if you could be more explicit in the chain of effects that lead you to expect higher resolution to lead to lower ozone enhancements resulting from a given aromatic emission.

3. You also have several type-o's in your next response: "There in fact consistent" should be "There IS in fact consistent", you're missing some spaces in "HO2 and RO2" and "This uncertainty limit" should be "This uncertainty limitS". Similar things are going on in subsequent responses, please just be sure to carefully proofread any new text for format, grammar and clarity.
