abstract = {A novel approach to characterize the physiological
conditions of plants from hyperspectral remote sensing data
through the numerical inversion of a light version of the
SCOPE model is proposed. The combined retrieval of
vegetation biochemical and biophysical parameters and
Sun-induced chlorophyll fluorescence (F) was investigated
exploiting high resolution spectral measurements in the
visible and near-infrared spectral regions. First, the
retrieval scheme was evaluated against a synthetic dataset.
Then, it was applied to very high resolution (sub-nanometer)
canopy level spectral measurements collected over a lawn
treated with different doses of a herbicide (Chlorotoluron)
known to instantaneously inhibit both Photochemical and
Non-Photochemical Quenching (PQ and NPQ, respectively). For
the first time the full spectrum of canopy F, the
fluorescence quantum yield (ΦF), as well as the main
vegetation parameters that control light absorption and
reabsorption, were retrieved concurrently using canopy-level
high resolution apparent reflectance (ρ*) spectra. The
effects of pigment content, leaf/canopy structural
properties and physiology were effectively discriminated.
Their combined observation over time led to the recognition
of dynamic patterns of stress adaptation and stress
recovery. As a reference, F values obtained with the model
inversion were compared to those retrieved with state of the
art Spectral Fitting Methods (SFM) and SpecFit retrieval
algorithms applied on field data. ΦF retrieved from ρ* was
eventually compared with an independent biophysical model of
photosynthesis and fluorescence. These results foster the
use of repeated hyperspectral remote sensing observations
together with radiative transfer and biochemical models for
plant status monitoring.},
