Dear Hannes,

It is my pleasure to accept your revised paper for publication in ACP as you have addressed all concerns of the reviewers.

Please consider the technical/minor points below.

With best regards,
Matthias


The linenumbers refer to the manuscript enclosed in the Author's Response
line 134: omit sentence. It is sufficient to state this in the figure captions.
line 139/140: the sentence seems incomplete. Add "are used to derive"?
line 304/305: I don't understand this sentence. Maybe stored is the wrong word here?
line 328: I am not sure if connectivity is the right word. What about connection or coherence? This also applies to line 522.
line 342: "on the other hand" instead of "by contrast", also in line 363.
line 345: observed variability
line 370: simplify sentence. "Our experience in the analysis of long-range transport events suggests a high reliablility of free-tropospheric trajectories."
line 399/400: omit. This redundant sentence is not needed in the discussion of Fig. 9
line 406: "also referred to as" instead of "nicknamed"
line 458: "shows" instead of "suffers"
line 456 and following paragraph: I have concerns about Figure 12. I don't see the trajectories dipping into the marine PBL. The lowest level is at maybe 800 hPa while I would expect a marine PBL to not exceed 1 km height. Even if the trajectories (after 315 h!) would lead to the marine PBL, the discussion would still be rather speculative. The reasoning regarding the conveyer belt is plausible though. Please revise this part to omit speculation.
line 485: omit "a lot of"
line 490: "are" insted of "have been"
Figure 5: I have a hard time separating the green and the blue lines. Please increase the contrast.
Figure 11: I don't agree with using figures that have already been published elsewhere. Even though both reviewers requested trajectories for this cases study, I think it is absolutely sufficient to refer to Trickl et al. (2014) if the case is discussed there in great detail. For the sake of clarity, please summarize previous findings regarding the case study. Also, please make sure to mention that specific details can be found in Trickl et al. (2014).
