Dear Dr. Burgard, dear co-authors,

In my view, the reviewers offer valid points following a very thorough read. At this stage, please, submit your revised manuscript with the edits you have already shown in your responses.

Regards

Dear Dr. Burgard, dear co-authors,

I thank you for the work done on the revised manuscript, which can be accepted for publication. However, in my view, the following items may be further improved:
- The term “self-similar” salinity profile is used only once, in the abstract. I suggest modifying this.
- In section 5.1, it may be relevant to remind the readers that the simulated brightness temperatures used to derive sea ice concentration in your study are at a frequency of 6.9 GHz. This frequency is not the typical frequency considered in algorithms used in the study of Ivanova et al. (2015).

Regards
