Based on optical absorption properties, measurements of leaf reflectance at fine spectral resolution can be used to estimate relative concentrations of different biochemical constituents. This paper evaluates the inversion capabilities of two leaf-level radiative transfer models to estimate needle chlorophyll content from measured needle reflectance & transmittance spectra. Validation of inversion algorithms is based on jack pine needles collected near Sudbury, Ontario for laboratory spectral & biochemical measurements. Comparisons of results using both the PROSPECT and LIBERTY models, as well as contrasts in the sensitivity of specific model parameters to accuracy, are presented.
