Dear authors,

Thanks for providing your replies to reviewers' comments. I would like to invite you to submit the revised manuscirpt for further review.

Dear authors,

The revised manuscript was reviewed by the two referees who reviewed the original article. They judge that your responses are satisfactory, and recommended the publication of this article.

I am also happy to see substantial improvements in the manuscript. One reviewer pointed out that Section 5.4 can be shortened, which is a valid point in my opinion. It is not necessary to merge it with Section 3, but please consider a more concise presentation of Section 5.4.

This paper describes the methods to generate a new DEM, so the release of the associated DEM is critically important. Because the review process is very close to complete, please upload the dataset to obtain DOI, and include DOI to this article. A part of the meta data can be described in data availability section (see my comment below for Table S4).

Below, please find other minor comments:

Figure 1: add distance scale to the two zoom-up insets. Cite a reference for RAMP and Matsuoka et al. (2021) for Quantarctica (https://doi.org/10.1016/j.envsoft.2021.105015); the former is a requirement to use Quantarctica, and the latter is the latest recommendation from the Quantarctica project.

P8L197ff: this paragraph presents the minimum elevation inconsistency, minimum elevation discrepancy and minimum elevation difference. These terms need to be better defined and readability of this paragraph needs to be improved.

P13L262: Is the citation of Figure 1 correct?

P14L294: briefly describe the magnitude of the temporal corrections based on Smith et al. (2020). For example, add mean and quantile values.

Tables 2 and 3: do you need to put elevation ranges into parenthesis?

Figure 14 and associated text (P30L470-477): the caption needs to be expanded. Why are there so few data points in this figure? The description/interpretation if this figure is also very limited.

P32L519: HEM -> DEM, typo?

Table S4: this is a description of the dataset associated with this article. So, please move this information to the data availability section (or delete).

I look forward to seeing the revised manuscirpt.

Dear authors,

Thanks for your careful revisions. Your responses are satisfactory, and I am happy to accept this article. Please correct one typo in Fig. 1 caption (Quantarctica, not QAntarctica), when you submit the final file for the production.

Congratulations.
