Dear Angela Santos et al.

Thank you for revise the manuscript ANGEO-2019-74. It is clear that your manuscript has been improved after the revision. I would like to thank the both reviewers for important suggestions/comments that they have posted. Based on your responses and the new version of the manuscript, I still not convinced about the presence of gravity waves in figures 9 and 10b). I guess the filtering process that you are using is not good to show the phase propagation of gravity waves in the dhF. I mean, the phase structures were not well defined and they have changed from a fixed frequency line to another. May you, please, work to improve these figures? I am going to consider the paper for publication in the Annales Geophysicae after your feedback.

Best regards,

Igo
