Using spectral information at the nir water absorption features to estimate canopy water content and biomass
Vegetation Canopy water content Biomass
2015/8/20
Biomass is one of the key biophysical variables of interest in vegetation studies and it can be defined in terms of fresh matter weight
or dry matter weight. Biogeochemical processes, such as photosy...
Towards red-edge positions less sensitive to canopy biophysical parameters using prospect-sailh simulated data
red-edge position linear extrapolation method leaf chlorophyll
2015/8/20
The position of the inflexion point in the red edge (680 nm to 780 nm), termed the red-edge position (REP) has been used as a measure to
estimate foliar chlorophyll or nitrogen content. In this study...
