The simulation of energy, water vapor and carbon dioxide fluxes over common crops by the Canadian Land Surface Scheme (CLASS)

The performance of the Canadian Land Surface Scheme (CLASS) was evaluated against observed eddy covariance flux data from four commonly cultivated crops growing in different climatic conditions. Of the four crops examined, wheat and soybean are C3 plants, whereas maize and millet are C4 plants. Physiological modules to simulate photosynthesis, respiration and growth for C4 plants were added to CLASS. Apart from maximum photosynthesis capacity, …
