Thank-you for your thorough responses to the reviewer comments. Please proceed with submission of the revised manuscript. Both reviewers requested a re-review of the revised manuscript, and so it will be sent back to them before the final editorial decision is taken.

Also, in response to the comment from Reviewer 2, showing all the NRCS, coherence, and phase images would make for very lengthy supplementary material. In my view this is best avoided. Thanks for yourr contribution to The Cryosphere, and I look forward to the revised manuscript.
