Thank you for your revised version. I am generally happy with your responses, but I would like to pick up two points raised by the reviewers, which could benefit from some further discussion.

You state that your results could be useful for model benchmarking of ESMs, but I’m still not clear how? ESMs do not represent processes at the spatial scales you investigate, so how can these relationships be used evaluate models? A bit more detail of what you mean here would be helpful.

Reviewer two pointed out that because of the global focus of ESMs, it might be interesting to extend this work to a larger domain. While I can understand that this is impossible for the current study, I think this is an important caveat to note, because the major aim of ESMs would be to predict the difference in SOC between tropical, temperate and boreal ecosystems. If you wanted to use your results as a benchmark, then one would need to establish to which extent the observed SOC scaling relationships in an arctic/boreal are useful to understand the large-scale tropical to arctic difference in SOC.
