"What is SIF? SIF (Solar induced chlorophyll fluorescence) is an electromagnetic signal emitted by the chlorophyll a of assimilating plants: part of the energy absorbed by chlorophyll a is not used for photosynthesis, but emitted at longer wavelengths as a two-peak spectrum roughly covering the 650–850 nm spectral range." (SENTINEL-5P+ INNOVATION)
650-850nm is the spectral range of SIF. People collect the data of 687nm, 730-780nm, 760nm, etc.. Some papers mentioned that the emission peaks are 685nm and 740nm. TROPOMI on Sentinel-5P+ collects SIF data emitted from two fitting windows: 743-758 nm window (baseline product) and 735-758 nm.
This paper should be a good reference of SIF.
