Thank you for your efforts in revision of the paper and your detailed replies to the referee comments. I've read through the replies and the revised version carefully, and I am satisfied that all major comments have been addressed in revision. Other comments have been addressed too or reflected on appropriately.

Given the overall positive tone of the referees comments regarding the potential utility of these findings, and their suitability for this journal, I am happy to accept this version subject to some final technical corrections.

I have some suggested minor edits to the revised version (mainly on the abstract text), spotted a need to clarify the temperature/elevation function used in the WARM model run, and spotted a few typos. There may be more, so please be diligent at the proof stage.

Dear authors,

I have now had a chance to look in detail at your revised manuscript, together with the reviewer comments, your replies, and the final AE report. Considering all of these pieces together, I am pleased to confirm acceptance of this paper. However, before uploading your final documents, please carefully review the further suggestions from the Associate Editor and make the corrections recommended. The AE has done a particularly thorough job on your paper and has provided a number of additional comments that, although all minor, will help the clarity and flow of the text considerably.

Also, before you upload your final figure documents, please check that all font sizes are large enough to be readable easily in the final printed version of the paper (and remember to double check this when you receive the proofs). Font size may be a particular concern for some of the smaller text on Figs. 2, 5, and 8. It will be easier to make any modifications at this stage, before typesetting.

One final point: I noticed that Jeremy Caves’ name is not spelled correctly in the Acknowledgments.

I look forward to seeing this paper published in its final form; I think it will provide a constructive step forward towards understanding orogenic-scale weathering fluxes.

Thank you for choosing Esurf for this work!
