Figure 7. Monthly patterns of canopy photosynthesis and macrometeorological properties. (i) Simulated canopy assimilation and respiration. Umbel gross assimilation (A_umbel), Culm gross assimilation (A_culm), Net canopy assimilation (A_net) and net ecosystem CH₂O flux (E_net). (ii). Monthly total culm, umbel and detritus respiration (including root/rhizome respiration). (iii). Measured and predicted light intensities above the canopy. Measured values based upon 10 year mean values of Muthuri et al. (1985). (iv). Measured and predicted temperatures. (v) Annual VPD cycle.
