Comparison of canopy-scale simulations of latent heat flux, using the BB, MED, and WUE models, against flux tower data collected above the Harvard Forest study site, the Ameriflux network site US-Ha1 as described by Bonan et al. (2014). A, BB model with g₁ = 9. B, MED model with the default g_1M = 4.45 (kPa)^0.5. C, WUE model with the default λ = 1.33 mmol water μmol⁻¹ CO₂. D, BB model with g₁ increased from 9 to 13. E, MED model with g_1M reduced from 4.45 to 2.8 (kPa)^0.5. F, WUE model with λ reduced from 1.33 to 0.714 mmol water μmol⁻¹ CO₂. The blue shaded area is the 95% confidence interval for the flux tower data; the blue line is the mean for the flux tower data; and the red line is the simulated value from the BB, MED, or WUE model.
