Figure 6. Predicted diurnal patterns of micrometeorological properties and associated canopy photosynthesis. (i) Predicted gross, net, culm and umbel photosynthetic rates on days 180 and 360. (ii) Predicted respiration for soil, culm and umbel elements. (iii) Simulated direct, diffuse and total solar radiation, (iv) Simulated diurnal pattern of ambient air temperature, (v) Simulated diurnal pattern of VPD.
