Abstract :
Simulated reflectance spectra of three mature hemiboreal forests are compared to top-of-canopy reflectance from helicopter measurements in the spectral range 400-1050 nm. Most of input parameters of the forest reflectance model FRT used in simulations have been measured in situ. The same data sets were used in the Radiation Transfer Model Intercomparison (RAMI). The reasons of the discrepancies between simulated and measured spectra are analyzed.
