Journal ArticleDOI
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
Remote sensing of solar-induced chlorophyll fluorescence (SIF) in vegetation: 50 years of progress.
Gina H. Mohammed,Roberto Colombo,Elizabeth M. Middleton,Uwe Rascher,Christiaan van der Tol,Ladislav Nedbal,Yves Goulas,Oscar Perez-Priego,Alexander Damm,Alexander Damm,Michele Meroni,Joanna Joiner,Sergio Cogliati,Wouter Verhoef,Zbyněk Malenovský,Jean-Philippe Gastellu-Etchegorry,John R. Miller,Luis Guanter,Jose Moreno,Ismael Moya,Joseph A. Berry,Christian Frankenberg,Pablo J. Zarco-Tejada +22 more
TL;DR: This review distills the historical and current developments spanning the last several decades of SIF heritage and complementarity within the broader field of fluorescence science, the maturation of physiological and radiative transfer modelling, SIF signal retrieval strategies, techniques for field and airborne sensing, advances in satellite-based systems, and applications of these capabilities in evaluation of photosynthesis and stress effects.
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
