Dear,
Following the discussion, I would like to invite the authors to prepare and submit a revised version of the manuscript. Although I agree with the referees that in terms of the science the revisions are minor, I follow referee 2 who would like to see a major effort in improving the readability and presentation of the manuscript. The measures discussed by the authors have the potential to improve this aspect of the manuscript.
Kind regards,

The authors properly addressed most of the concerns raised by the reviewers. One concern needs, however, more attention. Although the authors state in their cover letter that “We will send the revised manuscript to an language expert to improve the English and grammar”, I’m unsure this has happened. If it happened, the language needs to be checked again. There are still too many typos and inconsistencies which hampers the readability of the manuscript. The tenses of the verbs should follow the conventions in scientific writing. On page P7 the present tense is used “do” on P8, L1 the past tense is used. P8, L2 another present tense is used. In the methods section it is customary to use a form of the simple past tense to describe what you did in your study. Passive voice is preferred. If you are unsure search the web for “Using tenses in scientific writing”.

Install a spelling checker for Latex. Just on the first pages I spotted the following issues: P1, L16 replace “archieve” by “achieve”; P2, L1 replace “climx” by “climax”; P2, L2 delete one “the”; P2, L13 add subscript to CO2; P2, L15 add \, in Latex between 350 and ppm. Apply for all numbers followed by units.; P5, L16 replace “available enough space” by “enough space available”; P5, L19 replace “every” by “any”; P7, caption replace “with in” by “within”.

There is no space limit in Biogeosciences. So, there is no need to use acronyms. Writing in full as much as possible will largely increase the readability of the manuscript.

P15 Delete L10-14. The discussion should not start with a summary of the methods.

P15, L25-26 apply correct in-text citation format. Unless the author is the subject or object of the sentence the name and year should be between brackets. There is a difference between \cite and \citep in the Latex template for Biogeosciences.

P23, why was A4 included in the Appendix rather than the main text?

The text in the appendix as well as the figures need to be carefully checked and edited. Fig B5 remove h[!h!b]; Fig B6 check the units of the y-axis;
