This study uses the Multiband Reflectance Iteration (MBRI) algorithm to report sea ice albedo data in the Antarctic region. The accuracy was verified by comparing it with some observations and other products. The description and figures are clear and adequate. However, the structure of the manuscript could be improved. For example, many parts of the Result section are mixture of method and result. Some titles were not suitable.

1 Introduction

L36-37, This sentence is ambiguous.

L59, Blank Line.

2 Date

L85-88, I recommend rewriting this paragraph. Currently, it may be difficult for most readers to understand how these data described in 2.1 were used. Alternatively, move the data section after the methods section.

Sections 2.2 and 2.3 can be combined into one section entitled 'Comparative data'. Then, 2.2.1 Existing Antarctic sea ice albedo products. 2.2.2 In situ measurements. This may be clearer.

4 Result

L310-325, This paragraph is not the result. It should be moved to the 'Method' section. Also, L336-340 is not a result, but rather an introduction.

L371-385, This part is also the method.

L400-411, This part is the preliminary processing of the measured data, not the results.

L439-473, This section should be given a separate title because it is not about validation with in situ measurements.

L439, This study -> This section

Section 4.3, The title I suggest is “Temporal and spatial difference with other products”.

L475, I don’t think this section is “To explore the potential use of albedo in studies of Antarctic sea ice changes”. I recommend paying more attention to the comparison (just like L496-520). The use of present data can be conducted in future works.

5 Discussion

This section looks like a summary of the results. I didn’t see any discussion beyond the results. I recommend adding a discussion about the advantages and disadvantages of the current product and how these affect the accuracy (spatial or temporal). You could also discuss which situations are more suitable for using the present product due to its advantages.
