Canopy spectral invariants for remote sensing of canopy structure

2009 First Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing, 2009
The concept of canopy spectral invariants expresses the observation that simple algebraic combinations of leaf and canopy spectral reflectances become wavelength independent and determine two canopy structure specific variables - the recollision and escape probabilities.

Impact of rice canopy structure on canopy reflectance spectra

SPIE Proceedings, 2006
Plant canopy reflectance is affected not only by the optical properties of canopy components, but also by canopy structure. In this paper, the radiative transfer model was used to simulate rice canopy bi-directional reflectance to determine its sensitivity to leaf area index (LAI) and inclination.

Canopy Closure Rate and Forest Structure

Ecology, 1997
Natural disturbances produce openings in forest canopies. Gap opening and closure create a mosaic of regenerating phases in the forest, which are a source of environmental heterogeneity, contributing to the maintenance of community diversity. In this study we measured the rate of canopy closure using hemispherical photographs taken in the same points ...

Sunfleck dynamics and canopy structure in a Phaseolus vulgaris L. canopy

International Journal of Biometeorology, 1998
Photosynthetic photon flux density (PPFD) fluctuations were quantified in crops of beans (Phaseolus vulgaris L.) in the field as the canopy developed between July and October. Two different methods were used to select sunflecks and shadeflecks.

Simulation of canopy fluorescence as a function of canopy structure and leaf fluorescence

Remote Sensing of Environment, 1992
Abstract Canopy chlorophyll fluorescence depends on the variation of individual leaf response inside the canopy, the attenuation of incident exciting radiation, and the scattering of emitted radiation toward the sensor. A simple model is presented which takes into account leaf fluorescence profile inside the canopy, structural variations of the ...
