Dataset for: Diurnal cycles of passive and active fluorescence measurements at canopy level in potato crops

We performed active and passive measurements of diurnal cycles of chlorophyll fluorescence of potato crops at canopy level outdoors for 26 days. Active fluorescence measurements were performed using Ledflex, a fluorescence micro-lidar described in Moya et al. (2019), Photosynthesis Research, 142, 1-15, DOI: 10.1007/s11120-019-00642-9, capable of remote measurements under full sun-light of chlorophyll fluorescence in the wavelength range from 650 to 800 nm. Passive solar-induced fluorescence (SIF) measurements were performed with Spectroflex, an instrument based on the method of filling-in in the O2A and O2B absorption bands at 760 nm and 687 nm, respectively. A first version of Spectroflex was presented by Fournier et al., (2012), ISPRS J. Photogramm. Remote Sens. 68, 112–120, https ://doi:10.1016/j.isprsjprs.2012.01.003. Chlorophyll fluorescence measurements are able to determine plant stress, including those of pathogens. The Fluorescence Explorer (FLEX) project, It is a satellite of ESA that will be launch at 2025, It will give us chlorophyll fluorescence images from space and It will open possibility to detect diseased plants a large scale.”
