Please can you add the DOI of the code to the information in the supplement.

I have not fully assessed your revision as you failed to provide a diff file of the manuscript. This is always required, but particularly so in the case of a minor revision, as it usually enables the editor to assess the manuscript without sending it back to the reviewers.

Therefore, for this revision, please upload the same Manuscript, your revised supplement, and an Author's Response that is very much like the one you already wrote, but which additionally includes a diff file with respect to the version of the manuscript that is in the open review.

Thanks for your revised manuscript. It seems like BGC-val is an excellent tool that will be very valuable to biogeochem modellers.

Minor comments:
1. "The figures are exported in the raster graphics format, PNG, as this is the easiest format for exporting from the python graphical toolkit that we use (Matplotlib)."

I am puzzled by this as I also use matplotlib and always export vector graphics. In my configuration I have found SVG files to be the simplest to use. Please have another go. Raster figures are very disappointing in an online journal!

2. I completely agree with you that you should define your acronyms upon first use. Had you removed this explanation it would likely have been subsequently required to be re-inserted by the copy editors.

3. The allusion to the readme "file in the repository" on p3 is a bit disconcerting, as it is not clear quite what is being referred to. Perhaps you could call it something like an online code repository and maybe could reference the code availability section here. I'm not sure, but it needs something to indicate that this is a resource outside of GMD.

Thanks for the corrections! I am now happy to accept the paper.
