PLS saturation

Accuracy and limitations for spectroscopic prediction of leaf traits in seasonally dry tropical environments

A spectral information projects its foliar traits, each of which exists with diverse proportion in a leaf. When LMA was over 300, model prediction didn't work well. In that region, other foliar traits must have contaminated LMA signals on reflectance. That uniqueness distinguishes savana from the other ecosystems.
