TLDR
In this paper, a review of existing literature to determine the retrieval accuracy of the continuous plant traits is presented, focusing on three categorical plant traits (plant growth and life forms, flammability properties and photosynthetic pathways and activity) and five continuous plant trait (plant height, leaf phenology, leaf mass per area, nitrogen and phosphorous concentration or content).About:

TL;DR: In this paper, the authors assess 10 start-of-spring (SOS) methods for North America between 1982 and 2006 and find that SOS estimates were more related to the first leaf and first flowers expanding phenological stages.

Leaf chlorophyll content as a proxy for leaf photosynthetic capacity
TL;DR: This research challenges assumptions that simple NArea–Vcmax25 relationships can reliably be used to constrain photosynthetic capacity in TBMs, even within the same plant functional type and suggests that ChlLeaf provides a more accurate, direct proxy for Vc max25 and is also more easily retrievable from satellite data.

TL;DR: In this article, the best vegetation indices (index form and wavelengths) were determined on a generic simulated database to estimate CHL, LMA, LAI and Bleaf in a general way.

An introduction to the NASA Hyperspectral InfraRed Imager (HyspIRI) mission and preparatory activities

TL;DR: The NASA Hyperspectral InfraRed Imager (HyspIRI) as mentioned in this paper is comprised of a visible to short-wavelength infrared (VSWIR) imaging spectrometer and a thermal infrared (TIR) multispectral imager, together with an Intelligent Payload Module (IPM) for onboard processing and rapid downlink of selected data.

Quantifying forest canopy traits: Imaging spectroscopy versus field survey
TL;DR: In this paper, the authors used Carnegie Airborne Observatory visible-to-shortwave infrared (VSWIR) imaging spectroscopy with light detection and ranging (LiDAR) to assess the foliar traits of Amazonian and Andean tropical forest canopies.

Overview of the radiometric and biophysical performance of the MODIS vegetation indices
TL;DR: In this paper, the authors evaluated the performance and validity of the MODIS vegetation indices (VI), the normalized difference vegetation index (NDVI) and enhanced vegetation index(EVI), produced at 1-km and 500-m resolutions and 16-day compositing periods.

Determination of accurate extinction coefficients and simultaneous equations for assaying chlorophylls a and b extracted with four different solvents: verification of the concentration of chlorophyll standards by atomic absorption spectroscopy
TL;DR: In this paper, the extinction coefficients for chlorophylls a and b in diethylether (Smith, J.H. and Benitez, A.V., eds.), used in this paper as primary standards, were verified by magnesium determination using atomic absorbance spectrophotometry.

TL;DR: This paper provides an international methodological protocol aimed at standardising this research effort, based on consensus among a broad group of scientists in this field, and features a practical handbook with step-by-step recipes, for 28 functional traits recognised as critical for tackling large-scale ecological questions.

Let the concept of trait be functional
Cyrille Violle,Marie-Laure Navas,Denis Vile,Elena Kazakou,Claire Fortunel,Irène Hummel,Eric Garnier +6 more
TL;DR: An unambiguous definition of plant trait is given, with a particular emphasis on functional trait, and it is argued that this can be achieved by developing "integration functions" which can be grouped into functional response (community level) and effect (ecosystem level) algorithms.
