It was an accidental discovery, but a huge breakthrough.Tracking chlorophyll fluorescence from spaceallows us to watch the planet breathe in real time—
sunlight hits structures within a plant’s cells called chloroplasts,which are packed with chlorophyll pigments.When chlorophyll molecules absorb light, some of their electrons become excited.
is by radiating it back out at a different wavelength,producing what’s called chlorophyll fluorescence.During photosynthesis, the chlorophyll’s excited electrons
producing what’s called chlorophyll fluorescence.During photosynthesis, the chlorophyll’s excited electronsmove through that series of chemical reactions.
and how much carbon is being absorbed in a given system.Drops in chlorophyll fluorescence may also occurbefore visible signs of plant stress, making it a timely measure.
