This paper introduces a new approach to modeling stomatal function based on trait-based hydraulics.
This model will radically simplify, yet improve, Earth System Models, once incorporated.
Earth System Models do not simulate stomatal conductance, and hence photosynthesis, correctly. Here, a team from the NGEE-Tropics project introduce a simple, mechanistically accurate modeling approach. The model validated particularly well against multiple empirical datasets. Furthermore, the team proposes ways this model can be incorporated into Earth System Models (ESM), thus greatly improving ESM realism and accuracy.
