Editor Comments:

Novel approach to derive the MIZ width of the Atlantic sector in the Arctic from the CryoSat-2 delay-Doppler radar altimeter.

Dear authors.
Thank you for addressing the reviewers' and editor's comments from the preceding round.
Your revised manuscript has been re-reviewed. Pls address the set of comments received from reviewers in response to your revised ms. In additioa, pls also address my comments (below).

Editor's Comments:

General comments:
Figure 1: The top panel does not adequately depict the changes in the wavelength or wave height correctly. Also the ice floes in the MIZ are incorrect, while the sea ice in the Ice Pack is shown as one huge floe on either side of the lead.

l69: Wingham et al. [2006] do not refer to the "sea ice mass balance". Suggest to explore, for example, Ricker et al. [2018; https://doi.org/10.5194/tc-12-3017-2018].

l128L Chnage "Other satellites for the MIZ retrieval" to "Other satellites assisting in the MIZ retrieval"

l152: Add info as to how long typical Cryo2Ice sampling intervals last.

l185-186: Rewrite "As shown in Figure 1" to describe what is shown in Fig 1 that demonstrates that "larger SSD (...) corresponds to less power drop in the slant looks".

l215: Location names to be capitalized: Change "Greenland sea," to "Greenland Sea,".

l480: The argument "through wave-ice interaction (ice floe breaking, rafting, thermodynamic feedbacks, etc)." holds only if the later MIZ width is larger than the former. Can you show this?

l510: Rewrite "at: https://zenodo.org/record/8176585 (last access: 24 July 2023)" to be completely in brackets. No need for the URL to be in the main sentence.

Table 2: Suggest to add information for CS2 retrieval as to how many CS2 tracks were used for each calculation for each region.


Minor comments:
* Correct spelling of "in situ" is without hyphen but in italics. (line 2 and all other uses in this ms)

l5: Change "ice cover" to "sea ice" or "sea-ice cover".
l8: Replace "MIZs" with "MIZ events".

l18: Add "The" to read "The MIZ is...".
l18: "MIZ" has been defined and used in abstract already, suggest to remove here.
l18: The opening sentence is not informative, as you define MIZ with an undefined concept, the "sea ice edge". I also beg to disagree that the MIZ is deeper than the sea-ice edge.
l19: "swells" - Correct to "swell". The noun swell can be countable or uncountable. In more general, commonly used, contexts, the plural form will also be swell.
l25: Add "the" and correct "MIZs" to read "the MIZ plays ... role".
l25: Replace "potentially" with "the likely process" or just cut "potentially".

l38: Correct "close to" to "up to".
l41: To be correct add "by satellite-borne instruments" to read "To resolve waves in the MIZ by satellite-borne instruments,"
l41: Rewrite "high-resolution satellite payloads are typically required," to read "atellite payloads providing high spatial resolution are typically required,".
l41: Remove "various".
l43: Remove "These".
l45: Rewrite "The effective footprint should be at least finer than half of the wavelength, which is no more than a few hundred meters." to "The spatial resolution of these sensors needs to resolve wavelength in the order of few hundred meters, so in the order of 100 meter."
l46: Correct "MIZs" to "MIZ".
l47: Correct "MIZs" to "MIZ".
l47: Change "mainly due to their highly variant nature" to "largely due to its high temporal variability".
l48: Correct "MIZs" to "MIZ".
l48: Correct "observation is" to "observations are".
l49: Remove "potential".
l49: Correct "MIZs" to "MIZ".

l57-58" Change "and ... 2022." to read "and derived a 12-winter (2010 - 2022) record for the MIZ in the Atlantic Arctic based on CryoSat-2."
l58: Suggest to cut "The paper is organized as follows."
l60: Replace "typical cases of retrieval" to "case studies".
l60: Shorten by removing "Further".
l62: Remove "and carries out related analysis".
l63-64: Remove "Specifically, as shown through intercomparisons, the traditional SIC-based MIZ definition yields much narrower MIZs than our retrieval."
l64-65: Shorten "Finally, in Section 6 we summarise the paper and discuss related topics of the satellite-based observations of the MIZ." by connecting with the previous sentence.
l68: Remove "constantly".
l68: Correct "earth’s" to "Earth’s".
l68: Remove "for over 12 years".


As discussed with the authors, from here on language issues are not longer listed, instead the authors are referred to a (professional) service for improvements to the text.

l20: Correct "Consequently, the sea ice cover undergoes" to "This is a region where the sea ice undergoes".
