Interactive comment on “Low sensitivity of gross primary production to elevated CO2 in a mature Eucalypt woodland” by Jinyan Yang et al

This manuscript syntheses a large amount of data from the EucFACE project to examine the effects of Rubiscoversus RuBP limitation on photosynthesis under elevated CO2. The authors present leaf-level measurements, leaf-level modeling, and canopy scale modeling of ambient versus elevated CO2 conditions to illustrate that current projections of GPP under elevated CO2 are overestimated in mature forests due to biases towards light-saturated leaves. This work is scientifically relevant and pedantic. I want to commend the authors on their efforts and have minor suggestions to improve the presentation and make the work clearer to a wider audience.
