ED: Publish subject to technical corrections (13 Oct 2017) by François Dulac

Thank you for your revision and for contributing to the ChArMEx SI. I am pleased to accept your paper for publication pending a few technical corrections. My suggestions are listed hereafter:
-Remove the final dot in the title.
-Introduction: I think it would be useful that part of your response to the first general comment from Reviewer 1 (what you are going to retrieve and the interest of GRASP compared to LIRIC) is integrated at the end of section 1.
-Section 3: the term "SD" (top of p.6 and in Table 2) seems undefined.
-Section 4.1 (4 instances): "for the coarse mode" with an article.
-Section 4.1, p.7, line 37: "at lower wavelengths".
-Section 4.1, p.8, line 6: do you mean "for the dust layer" or "for dust layers"?
-Section 4.1, p.8, line 9: "could be due to the fact that the in-situ".
-Section 4.1, p.8, line 11: "these measurements could".
-Section 4.2, p.9, lines 2-3: replace "first" by "lower" and shift "in the lower two kilometers of the atmosphere" after "expected".
-Section 4.2, p.9, line 15: replace "and seems to be canceled" by "probably"; rather write "the combined used of lidar and sun-photometer data".
-Section 4.2, p.10, line 21: "a moderate concentration".
-Section 4.2, p.10, line 21: "different composition from the layer"; can you refer to appropriate Figures (9 and 10, I presume) at end of line ?
-Section 5, p.10, line 28: "located above".
-Section 5, p.11, line 17: I suggest to complete the first sentence of your last paragraph with the statements ", and also to obtain fine and coarse mode [...] AERONET inversion", given in the second part of your reply to the 1st comment from referee 1 (already mentioned above for an addition to the introduction).
-Section 5, p.11, line 19: "really different from those of the".
-Section 5, p.11, line 20: "southern Europe"; "to test a more complete".
-Section 5, p.11, line 21: "try to combine one".
-Section 5, p.11, line 22: "different heights"; "try improving".
-Section 5, p.11, line 23: "to use a database from global".
-References: Torres et al. (2017) is now published, please replace "Accepted." by "10, 3743-3781, doi:10.5194/amt-10-3743-2017".
-Fig. 5: I believe it would be useful to plot vertical error bars representing the std. dev. (±0.04 as I understand) of the airborne retrievals added in the revised version of the 4 plots.

Short summary

In this study, vertical profiles and column integrated aerosol properties retrieved by GRASP (Generalized Retrieval of Atmosphere and Surface Properties) algorithm are evaluated with in situ airborne measurements made during the ChArMEx-ADRIMED field campaign in summer 2013. Differences between GRASP retrievals and airborne extinction profiles are in the range of 15 to 30 %. Also, the total volume concentration differences between in situ data and GRASP retrieval ranges from 15 to 36 %.
