Short summary

This study addressed a major knowledge gap in the response of forest productivity to elevated CO₂. We first quantified forest productivity of an evergreen forest under both ambient and elevated CO₂, using a model constrained by in situ measurements. The simulation showed the canopy productivity response to elevated CO₂ to be smaller than that at the leaf scale due to different limiting processes. This finding provides a key reference for the understanding of CO₂ impacts on forest ecosystems.
