SpletThe analysis of the “red-edge” is to detect the shift of the “red-edge” wavelength due to the stress-induced change in chlorophyll concentration and leaf area index (LAI, m2 leaf area/m2 ground area). A number of vegetation indices (VIs) could be used as an alternative for this purpose (Broge and Mortensen, 2002). SpletA methodology is described for the validation of Medium Resolution Imaging Spectrometer (MERIS) Terrestrial Chlorophyll Index (MTCI) data over heterogeneous land surfaces in an agricultural region in Southern Italy. The approach involves the use inverse canopy reflectance modeling techniques to derive maps of canopy chlorophyll content (CCC) …
