Dear Dr Yu

many thanks or your revised manuscript, which I am happy to accept for publication subject to minor revisions that relate to the manuscript structure and a typo.

Moving frequently cited tables and figures to the main paper makes it more readable and less fragmented. Having reviewed the ACP manuscript guidelines, these clearly stipulate that "Supplementary material is reserved for items that cannot reasonably be included in the main text or as appendices. These may include short videos, very large images, maps, CIF files, as well as short computer codes such as matlab or python script. In no case can supplementary material contain scientific interpretations or findings that would go beyond the contents of the manuscript. [...] Normal size figures, tables, as well as technical or theoretical developments that do not need to be included in the main text should be included as appendices."

The figures and tables in your current supplement are all normal-sized and should therefore appear either in the main text or as appendix (i.e. the figures and tables I previously highlighted as well as Figs. S1 and S2). In my view, figures S1, S2 and S4 could appear as Appendix if you prefer; however the other figures (S3, S5 to S9) and tables S1 and S2 all refer to specific results or discussion points of the paper and should be merged with the main text. For example, table S1 is already referenced 6 times in the main text. It is not identical to the table in Harris et al. 2017 (and, actually, in the latter paper the corresponding table is part of the main paper. Table S2 is referenced 3 times and itself references 7 publications. Again, these are strong reasons for making this table part of the main text. Fig. S3 refers to a result of your study and is discussed extensively in the first paragraph of the main section. This is clearly not just an appendix. Similar considerations apply to Figs. S5 to S9.

402 & 403 & Table 1 : spelling of "deseasonalized"
