Improved global estimation of seasonal variations in C3 photosynthetic capacity based on eco-evolutionary optimality hypotheses and remote sensing

The maximum carboxylation rate of plant leaves (V cmax ) at 25 °C (V cmax25 ) is a fundamental parameter in terrestrial biosphere models (TBMs) to estimate carbon assimilation of C3 biomes. It has been reported that ignoring the seasonal variations in V cmax25 induces considerable uncertainties in TBMs. Recently, a model was developed to estimate V cmax25 of C3 biomes mechanistically from climate data based on eco-evolutionary optimality …
