Fig. 20.2a-c. Validation of the single-species homogeneous canopy model for the Mediterranean evergreen shrub species Quercus coccifera (Caldwell et al. 1986). a Correspondence of measured and simulated leaf temperatures near the top (solid symbols) and
bottom (open symbols) on clear days at four different times of year. The coefficient of
determination is 0.90. b Correspondence between simulated and measured leaf conductance in different canopy layers for several dates in all four seasons of the year. The
coefficient of determination based on 251 observations is 0.87. Most of the measured data
were needed for parameter estimation in the conductance model. In the inset is a similar
relationship between measured and simulated leaf conductance for a data set not used for
parameter estimation. c Correspondence between simulated and measured net photosynthesis in different canopy layers for several dates in all four seasons of the year. The
coefficient of determination based on 173 observations is 0.91. Most of the measured data
were needed for parameter estimation in the conductance model. In the inset is a similar
relationship between measured and simulated leaf conductance for a data set not used for
parameter estimation
