Structural and Spectral Analysis of Cereal Canopy Reflectance and Reflectance Anisotropy

Modelling Canopy Reflectance with Spectral Invariants

ABSTRACT: The concept of using spectral invariants to describe the scattering and absorption processes in a vegetation canopy has been developed for application to remote sensing studies in recent years. It has been shown that an average ‘recollision probability’ can describe the main impacts of structure on directional-hemispherical scattering and transmission, and there has been some indicati...

Soil Spectra Contributions to Grass Canopy Spectral Reflectance

The soil or background spectra contribution to grass canopy spectral reflectance for the 0.35 to 0.80 fJ-m region was investigated using in situ collected spectral reflectance data. Regression analysis was used to estimate accurately the unexposed soil spectral reflectance and to quantify maxima and minima for soil-green vegetation reflection contrasts. generally be impractical to take detailed...

Canopy near-infrared reflectance and terrestrial photosynthesis

Global estimates of terrestrial gross primary production (GPP) remain highly uncertain, despite decades of satellite measurements and intensive in situ monitoring. We report a new approach for quantifying the near-infrared reflectance of terrestrial vegetation (NIRV). NIRV provides a foundation for a new approach to estimate GPP that consistently untangles the confounding effects of background ...
