Dear author
The revised version of your manuscript addresses well the comments provided by the two reviewers. I think the new version has improved in readability compared to the previous version. However, the model description section is still a hard read. This is typical of model description papers, and I rather have a detailed and rigorous model description than a simplistic and sloppy description. So, I think the manuscript is now acceptable for publication in GMD after a few minor additional revisions.
On page 6, lines 23-24, I had difficulty understanding your statement about allocation to leaf area. Normally C is allocated to a leaf C pool in terms of mass, and the term allocation to leaf area sound rather unusual to me. This issue is only resolved on page 8, lines 5-6, where the equation for LAI is provided. Can you perhaps write the statement on page 6 differently, making more clear that allocation occurs to a leaf C pool from which LAI is calculated according to a leaf carbon per area parameter?

A few other technical corrections:
-P2, l12: Change ‘have’ for ‘allow’.
-P7, l13: add ‘is’ after photosynthesis.
-P9, l11: add ‘of’ after number.
-P29, l22: remove ‘of’.
-P30, l16: ‘biome’ in singular.
-P35, l27: change to ‘complements’.
