Dear authors
Thank you for making the revisions and updates. The paper reads very well and I believe will be a useful resource for researchers.

One minor suggestion - I wonder if on line 32 it is worth adding an old classical reference on earths water balance to support the claim that P and E is balanced by continental runoff. I thought here of a table in the Brutsaert (2005) book "Hydrology" where authors like Budyko and others are mentioned (Brutsaert's Table 1.1). Of course I leave this to your discretion.

A final note - On line 565, I would join the one-sentence paragraph and the new paragraph to make a single paragraph.

Best of luck with your future research
Kind Regards
Matt Hipsey
