Marchenko Green’s Function Retrieval in Layered Elastic Media from Two-Sided Reflection and Transmission Data

Round 1

Reviewer 1 Report

The study "Marchenko Green’s function retrieval in layered elastic media from two-sided reflection and transmission data" is very well written and complete from all aspects. I believe it can be accepted as it with minor English language modification. 

Author Response

Thank you for your review. We have done our best to write this paper properly.

Reviewer 2 Report

This report introduced an 321 auxiliary equation and a coupled equation, by concatenating these equations. The methodology could potentially be extended to account for mild lateral variations, dissipation, anisotropy and heterogeneities. The result is convincing and valubale, therefore can be recommanded for publication.

Thank you for your review.

Reviewer 3 Report

1- The contributions of the paper should be clearly outlined in the last paragraph of the Introduction section to justify the motivation for this study. it is not very clear for a general reader.

2- symbols and parameters in equations should be defined (it is necessary).

3 - quality of figures should be improved. They are not acceptable for publication.

4-  double-check the grammar of the text.

5 - reference is not adequate and too short.

Author Response

1. We have added the following text to the introduction (line 44): "In this way, we can apply exact (data-driven) Marchenko redatuming of two-sided data in a layered elastic medium, which is the main contribution of this paper".
2. We have checked if all symbols and parameters are defined. We found only one symbol that we forgot initially: \omega in Appendix B. We have corrected this on line 360, by adding "where \omega denotes the angular frequency".
3. We have checked all our figures for potential improvements and came up with the following modifications: (a) We have added units to the x- and y-axis labels in Figures 1 and 2 (these were already defined in the figure caption of figure 1, but initially forgotten in figure 2); (b) We have removed "(alpha)" and "(beta)" from the y-axis labels of J^P and J^S in figure 4 (which appeared to be redundant). Apart from these, we don't see where our figures fall short.
4. With respect to grammar, we did the best we could do.
5. We have added the following text to the introduction (line 10): "For an introduction to this subject, the numerical implementation of the Marchenko equation, field data applications and recent developments, see [3-4], [5-7]. [8-10] and [11], respectively". Eight references [3-10] have been added to the manuscript, leading to a total of 51 references (which should be sufficient in our opinion).
