Fig. 2. Fluorescence–reflectance–transmittance (FRT) model simulation of leaf reflectance with the effects of fluorescence flux. Parameters used for the simulation: = 0.085, C_a+b content = 50 µg/cm², D_L = 0.075 mm, F_L = 688 nm, B_L = 30 nm, F_H = 746 nm, B_H = 52 nm, f ratio F_H/F_L = 0.94, labeled as r* (with fluorescence), r (without fluorescence).
