Dear Authors,

thank you very much for your detailed replies and the revision of the
manuscript, and also for providing a document with highlighted modifications.
Nevertheless, I think some final polishing is needed before the publication in
ACP..

First of all, using the term "vertical variability" or just "variability" is
misleading, since "variability" is mostly connected to "changes with time".
Therefore, in many positions in your text, you might better
write "vertical fine structure", or "finer vertical structure" or similar.
Please recheck your text and consider this, where it is appropriate.

Moreover, some further formulations might need improvement
(line numbers refer to the manuscript with highlighted changes):

line 20: Is here "variability" with respect to time or vertical dimension meant?

line 24-25: How can "underrepresented waves" enhance the variability?

line 77: How can something "unresolved" have an impact? Or do you mean
"role" instead of "impact"?

line 454: Is the "enhanced variability" in time or in the vertical?

caption of Fig. 8: "fair" instead of "far"?

Please check.

Yours,

Patrick Jöckel
