Effects of Vegetation Directional Reflectance on Sun-induced Fluorescence Retrieval in the Oxygen Absorption Bands
Remote sensing of sun induced fluorescence (SIF) in absorption bands is based on the analysis of the changes in atmospheric absorption features between reflected and incident sunlight. Indeed, chlorophyll fluorescence increase the reflected light in the same amount insight and outside the absorption features, thus reducing the apparent depth of bands. However, incoming light is a mixture of dir...
متن کاملInvestigation of Atmospheric Effects on Retrieval of Sun-Induced Fluorescence Using Hyperspectral Imagery
Significant research progress has recently been made in estimating fluorescence in the oxygen absorption bands, however, quantitative retrieval of fluorescence data is still affected by factors such as atmospheric effects. In this paper, top-of-atmosphere (TOA) radiance is generated by the MODTRAN 4 and SCOPE models. Based on simulated data, sensitivity analysis is conducted to assess the sensi...
متن کاملAssessing Band Sensitivity to Atmospheric Radiation Transfer for Space-Based Retrieval of Solar-Induced Chlorophyll Fluorescence
In contrast to ground-based solar-induced chlorophyll fluorescence (Fs) detection, the influence of atmospheric radiation transfer is the major difficulty in Fs retrieval from space. In this study, we first simulated top-of-atmosphere (TOA) radiance using FluorMODgui3.1 and MODTRAN5 code. Based on the simulated dataset, we analyzed the sensitivities of five potential Fs retrieval bands (Hα, K I...
متن کاملAuxiliary Material for Paper 2010GL045896 Disentangling chlorophyll fluorescence from atmospheric scattering effects in O2A-band spectra of reflected sun-light
We perform a retrieval simulation on (1) how the fluorescence emission F s affects the retrieval of surface and scattering parameters from space-based observations of the O2A-band and on (2) how the retrieval of such parameters can mask the fluorescence signal. Here, we consider as retrieval parameters surface pressure ps, Lambertian surface albedo r, the aerosol optical density τ (AOD in main ...
