Crop canopies exercise some control on the exchange of mass and energy with the atmosphere by regulating their stomatal resistance. A hypothesis is proposed in which regulation of stomatal resistance is controlled jointly by the water status of the canopy and photosynthetic capacities of the leaves in the canopy. This hypothesis was incorporated into an ecosystem simulation model, which was tested against data for mass and energy exchange measured over a growing barley crop at different levels of canopy cover and soil water content. Standard differences (square root of the mean square difference) between simulated and measured hourly values for net radiation, latent heat, and sensible heat over the soil-canopy surface were < 50 W M-2 during each date for which comparisons were made, which is within the range of experimental error [...].
