Model evaluation of simulated gross primary productivity in the absence of foliar respiration ( defined as G_P plus canopy foliar respiration, R_C), G_P and R_C in Mg C ha⁻¹ a⁻¹ using available observations from ‘bottom-up’ and eddy correlation. Upper and lower bounds of uncertainty correction for eddy correlation values are related to a night-time friction velocity threshold used [35]. Data sources for each site are described in the methods.
