Biophysical and Biochemical Sources of Variability in Canopy Reflectance
TLDR
In this article, a combination of field and modeling techniques were used to quantify the relative contribution of leaf, stem, and litter optical properties (incorporating known variation in foliar biochemical properties) and canopy structural attributes to nadir-viewed vegetation reflectance data.About:

Multispectral and hyperspectral remote sensing for identification and mapping of wetland vegetation: a review
TL;DR: In this paper, the authors provide an overview on the status of remote sensing applications in discriminating and mapping wetland vegetation, and estimating some of the biochemical and biophysical parameters of the vegetation.

Global synthesis of leaf area index observations: implications for ecological and remote sensing studies
TL;DR: The first global synthesis of plant canopy leaf area index (LAI) measurements from more than 1000 published estimates representing ∼ 400 unique field sites was presented in this article, where the data provide input to terrestrial ecosystem and land-surface models, for evaluation of global remote sensing products, for comparison to field studies, and other applications.

Hyperspectral discrimination of tropical rain forest tree species at leaf to crown scales
TL;DR: In this paper, the authors investigated the utility of high spectral and spatial resolution imagery for the automated species-level classification of individual tree crowns (ITCs) in a tropical rain forest (TRF).

Moisture Effects on Soil Reflectance
David B. Lobell,Gregory P. Asner +1 more
TL;DR: In this paper, measurements of reflected shortwave radiation (400-2500 nm) were acquired in a laboratory setting for four different soils at various moisture contents, revealing a nonlinear dependence on moisture that was well described by an exponential model, and was similar for different soil types when moisture was expressed as degree of saturation.

Designing a spectral index to estimate vegetation water content from remote sensing data: Part 1 - Theoretical approach
TL;DR: In this paper, a spectral index is used to retrieve vegetation water content from remotely sensed data in the solar spectrum domain. But the spectral index was not optimized for the SPOT-VEGETATION sensor.

A soil-adjusted vegetation index (SAVI)
TL;DR: In this article, a transformation technique was presented to minimize soil brightness influences from spectral vegetation indices involving red and near-infrared (NIR) wavelengths, which nearly eliminated soil-induced variations in vegetation indices.

Derivation of leaf-area index from quality of light on the forest floor
TL;DR: The Leaf—area index of a forest can be measured by determining the ratio of light at 800 μm to that at 675 μm on the forest floor, based on the principle that leaves absorb relatively more red than infrared light.

Light scattering by leaf layers with application to canopy reflectance modeling: The SAIL model
TL;DR: In this article, the scattering and extinction coefficients of the SAIL canopy reflectance model were derived for the case of a fixed arbitrary leaf inclination angle and a random leaf azimuth distribution.
