Nocturnal Light Emitting Diode Induced Fluorescence (LEDIF): A new technique to measure the chlorophyll a fluorescence emission spectral distribution of plant canopies in situ

<p>This repository contains&nbsp;data reported in the below study:</p> <p>Atherton, J., Liu, W. and Porcar-Castell, A., 2019. Nocturnal Light Emitting Diode Induced Fluorescence (LEDIF): A new technique to measure the chlorophyll a fluorescence emission spectral distribution of plant canopies in situ.&nbsp;<em>Remote Sensing of Environment</em>.</p> <p>Each text file contains the data-set&nbsp;used to produce the relevant figure (see file name). You can find the data to produce A.4. online at&nbsp;&nbsp;https://avaa.tdata.fi/web/smart/smear/&nbsp;</p> <p>Please pay attention to the following before using this data.</p> <ol> <li><strong>Figure2_lampRadPanel_Wm2srnm.txt</strong>: Note that the shapes are of interest here. The magnitude is not the same as the incident light at top of canopy, as these spectra were measured in a laboratory. See paper section&nbsp;A.1. for more details.&nbsp;</li> <li><strong>Figure3_LEDIFspectra_Wm2srnm.txt</strong>: This&nbsp;data contains&nbsp;the whole observed spectrum including the non-fluorescence regions, which were saturated (warped)&nbsp;in the visible. The fluorescence region is approximately &gt; 650 nm. &nbsp;&nbsp;</li> <li><strong>Figure4_AQYspectra_nm.txt</strong>: As with Figure3 the whole spectrum is included here.</li> <li><strong>FigureA3_repLEDIFspectra_[pmay/psep/usep]._nm.txt</strong>:&nbsp; Data from which the mean spectra (Figure3) were calculated, including the uncorrected red spectra. I have split these by canopy&nbsp;type to avoid name conflicts.</li> </ol> <p>&nbsp;</p>
