Dear Author,
Thank you for your revised manuscript. Your manuscript answers most comments from the reviewers, but I consider that some of the reviewers’ remarks are still not addressed in a fully satisfactory way. So I would like you to consider the remarks in the attached document and provide an updated manuscript addressing them, before I can consider it for publication.
With best regards,
Sophie

Dear Author,

Thank you very much for the revised manuscript, which answers almost all remarks I made in my previous "decision". Before publication, I just would like to draw your attention on the following issues:

- for the OASIS3-MCT_4.0 reference, please use (with the http reference if you find this appropriate) : Valcke, S., Craig, A. and Coquart, L. (2018), OASIS3-MCT User Guide, OASIS3-MCT4.0, CECI, Université de Toulouse, CNRS, CERFACS - TR-CMGC-18-77, Toulouse, France (https://cerfacs.fr/wp-content/uploads/2018/07/GLOBC-TR-oasis3mct_UserGuide4.0_30062018.pdf)

-p.4, l10-20: It is still not clear why you you split the description into two paragraphs "1. NC/GC" (under which you describe NC or NC/GC or GC solutions), and "2. LC/GC" (under which you have LC/GC and LC solutions)? In your reply, there is just an "explanation" written in red without further justification.

-p.16-17: I still think that Fig. 8 does not bring any additional information. In particular, the "as shown in Fig. 8", L2 P17 does not seem relevant as nothing specific about the front algorithm is shown in Figure 8. In Fig. 7 captions in "local intersection proceeds between atmosphere (Quadrangle) and ocean (Polygonal) grids", maybe add "target" before "atmosphere" and "source" before "ocean".

-Fig 11 b), yes I think that some confusion arises as the solution from the opposite site of the sphere shows through America. It would be better to have all continents in white, or at least explain why they are not all white to avoid the confusion ...

and on the following minor points:

-p.8, l.31, please put the citation "Tautges and Caceres (2009)" between parentheses.

-p.9, l.4, please consider replacing "processes" by "functions" or something similar

With best regards
