Scaling-up and model inversion methods with narrowband optical indices for chlorophyll content estimation in closed forest canopies with hyperspectral data

TL;DR: Study of the merit function in the numerical inversion showed that red edge optical indices used in the minimizing function such as R/sub 750//R/sub 710/ perform better than when all single spectral reflectance channels from hyper-spectral airborne CASI data are used, and in addition, the effect of shadows and LAI variation are minimized.
Journal ArticleDOI

Vegetation stress detection through chlorophyll a + b estimation and fluorescence effects on hyperspectral imagery.

TL;DR: A derivative chlorophyll index (DCI) was developed, a function of the combined effects of CF and Ca + b content, and used it to detect vegetation stress and accurately estimated the effective quantum yield by inverting the FRT-PROSPECT model.
Journal ArticleDOI

Chlorophyll Fluorescence Effects on Vegetation Apparent Reflectance: I. Leaf-Level Measurements and Model Simulation

TL;DR: In this article, a series of laboratory measurements of spectral reflectance and transmittance of individual leaves and from a modeling study are presented which demonstrate that effects of natural chlorophyll fluorescence (CF) are observable in the red edge spectral region.
Journal ArticleDOI

The FLuorescence EXplorer Mission Concept—ESA’s Earth Explorer 8

TL;DR: A mission concept overview of the scientific goals, the key objectives related to fluorescence, and the requirements guaranteeing the fitness for purpose of the resulting scientific data set is provided.
