Round 1
Reviewer 1 Report
Dear authors,
Thank you a lot for your manuscript “Retrieval of snow properties from Sentinel-3 Ocean and Land Colour Instrument”. The knowledge about the distribution of grain size and albedo is very important and your manuscript contributes to fill this gap with a beautiful, global data set. Nevertheless, I am very skeptical if your manuscript is worth for publication for following reasons:
1. The manuscript has no clear line and it is very confusing to read. Who is your audience and which story do you have for the reader?
2. The manuscript has no structure. In chapter 2 “Materials and Methods”, the data of S3 are not explained, in chapter 3 “Results”, no results are discussed, but new formulas are derived – why are you not following the traditional content and hence the structure of papers? The theory of the relation between snow grain size and albedo is not clear. Please, revise this chapter.
3. The manuscript is definitely too long and you are losing the attention of the reader. Keep it short and simple!
4. With all the explanations how to process the data and which parameters should be used, it sound more like a delivery or manual. My suggestion would be to put all your scripts, processing explanations, and used parameters onto you internet page https://portal.polartep.io and to reduce your manuscript to most important points like the theory, results, and accuracy assessment.
5. 31 Authors are definitely too much! I am very sorry.
6. Revise your English and take care of the tenses.
7. All figures should have a coordinate system and the same projection (Fig. 4.2 d is smaller than Fig 4.2. c). Take care that the values have the same colors and not to use different scales and colors for the same content (Fig 4.1. a and Fig 4.2 a).
8. Have you compared your results with the snow albedo derived of MODIS? It would be great to have a comparison in 2D and not only for few points.
9. In Kokhanovsky et al. (2018), you already derived the snow reflectivity of snow. What is the difference between snow reflectivity and albedo and hence of the formulas?
10. Table 3.5 lists the difference between OLCI- and in-situ grain sizes. Are these the results of all AWS in Greenland? A comparison during the whole winter would be interesting – changes the accuracy assessment in dependence of the seasons? How changes grain size and albedo during derived of S3 over one year?
11. Corresponds the grain size to the glacier zones? I am missing the discussion about the spatial distribution of the grain sizes and the albedo in a glaciological frame.
Good luck!
