The black line shows irradiance at ground level and the red line shows a typical chlorophyll fluorescence spectrum, with fluorescence peaks at 685 nm and 740 nm (maxF685, maxF740). Solar-induced fluorescence (SIF) is estimated at the closest Fraunhofer lines to these maxima, located within the O2B lines centered at 687 nm and O2A lines centered at 760 nm (F687, F760).
