Comparing optimal and empirical stomatal conductance models for application in Earth system models

Earth system models ( ESM s) rely on the calculation of canopy conductance in land surface models ( LSM s) to quantify the partitioning of land surface energy, water, and CO 2 fluxes. This is achieved by scaling stomatal conductance, g w , determined from physiological models developed for leaves. Traditionally, models for g w have been semi‐empirical, combining physiological functions with empirically determined calibration constants. More...
