Dear authors,

I have received your revision of your submission “How drought severity constrain GPP and its partitioning among carbon pools in a Quercus ilex coppice?” in Biogeosciences. In general, I am satisfied with your responses to reviewers' comments. But before the final acceptance, I have
a few minor suggestions:

1) I suggest to add one extra panel in Figure 4 to show the ANPP_leaf with WSI_t. By doing this, it would be easier to demonstrate your point that ANPP_leaf is more correlated with previous year water condition rather than the current year.

2) I agree with Reviewer #1's suggestion that there is some redundancy between Figure 5 and Figure 6. I thus suggest to combine these two figures as one figure with two panels.

3) Your response to Reviewer #1's second major point (related to your figure 1 and 2 in the response ) is important for readers to understand the procedures/methods of carbon budget estimation. I strongly encourage you to incorporate these two figures in your reply into your main text.

Best wishes,

Dr. Kaiyu Guan
