In November 2015, the FLuorescence EXplorer (FLEX) was selected as eighth Earth Explorer mission of European Space Agency. The tandem concept will provide measurements at a spectral and spatial resolution enabling retrieval interpretation full chlorophyll fluorescence spectrum emitted by terrestrial vegetation. This paper provides overview scientific goals, key objectives related to fluorescence, requirements guaranteeing fitness for purpose resulting data set. We present design time...
Abstract Terrestrial gross primary production (GPP) is an important parameter to explore and quantify carbon fixation by plant ecosystems at various scales. Remote sensing (RS) offers a unique possibility investigate GPP in spatially explicit fashion; however, budgeting of terrestrial cycles based on this approach still remains uncertain. To improve calculations, spatio‐temporal variability must be investigated more detail local regional The overarching goal study enhance our knowledge how...
Abstract Variations in photosynthesis still cause substantial uncertainties predicting photosynthetic CO 2 uptake rates and monitoring plant stress. Changes actual that are not related to greenness of vegetation difficult measure by reflectance based optical remote sensing techniques. Several activities underway evaluate the sun‐induced fluorescence signal on ground a coarse spatial scale using space‐borne imaging spectrometers. Intermediate‐scale observations airborne‐based spectroscopy,...

In this paper we compare two different methodologies for Fractional Vegetation Cover (FVC) retrieval from Compact High Resolution Imaging Spectrometer (CHRIS) data onboard the European Space Agency (ESA) Project On-Board Autonomy (PROBA) platform. The first methodology is based on empirical approaches using Indices (VIs), in particular Normalized Difference Index (NDVI) and Variable Atmospherically Resistant (VARI). second Spectral Mixture Analysis (SMA) technique, which a Linear Unmixing...
A characteristic spectral emission is observed in vegetation chlorophyll under excitation by solar radiation. This emission, known as solar‐induced fluorescence, occurs the red and near infra‐red regions. In this paper a new methodology for estimation of fluorescence from spaceborne airborne sensors presented. The signal included an atmospheric radiative transfer scheme so that surface reflectance are retrieved consistently measured at‐sensor radiance. tested on images acquired Medium...
