As chlorophyll absorbs light to convert it to energy, it emits a bit of fluorescent light. Â Using existing satellites NASA figured out how to measure this florescence.
Below, you see North America during growing season…wherein it demonstrates that during this time of year it is the most productive (in terms of amount of photosynthesis) area on the planet. Â _This includes being more active than the Amazon basin_.
