Chlorophyll Fluorescence from Vegetation on Land

Measurement Definition*: Solar induced chlorophyll fluorescence occurs during photosynthesis. It exhibits a strong linear correlation with terrestrial gross primary production (GPP). Direct global space borne observations of the fluorescence emission provide the same or better GPP estimations as those derived from traditional remotely-sensed vegetation indices using ancillary data and model assumptions.
