FIGURE 8.
Sensitivity of the light use efficiency (LUE) of NNC‐part to the diffuse to direct radiation ratio. The trend of LUE by NNC‐part with respect to the diffuse radiation ratio is reported in the panels (a–d; here LUE is normalized for comparison purpose). The difference between LUE (µmol CO2/W) as estimated by NNC‐part and that from the daytime method (DT) standard partitioning method is also reported (e–h); the statistics were aggregated per diffuse to direct radiation class (here estimated by the proxy 1‐SW_IN/SW_POT and reported as percentage). We reported the following statistics of x (x = LUE(NNC‐part) − LUE(DT)): the median values (bar), the mean value (*), the interquartile range (by brackets). Only LUE at midday is used in this figure
