A new hyperspectral index for chlorophyll estimation of a forest canopy
Original language description
A new optical index named Area under curve Normalised to Maximal Band depth between 650-725 nm (ANMB650-725) is proposed to estimate the chlorophyll content of a Norway spruce (Picea abies, /L./ Karst.) crown. This index was designed to exploit modifications of a vegetation reflectance signature invoked within the red-edge wavelengths mainly by the changes in leaf chlorophyll content. ANMB650-725 is based on the reflectance continuum removal of the chlorophyll absorption feature between wavelengths of 650-725 nm. Suitability of the index and sensitivity on disturbing factors was tested using a 3D Discrete Anisotropic Radiative Transfer (DART) model coupled with a leaf radiative transfer model PROSPECT adjusted for spruce needles. The results of the ANMB650-725 abilities within a coniferous forest canopy were compared with the performance of the chlorophyll indices ratio TCARI/OSAVI.
