Photosynthesis overview


Photosynthesis activity is changing in different regions of the world because of human induced climate change. A new technology, which uses satellites to measure fluorescence, the light plants emit when sunlight excites chlorophyll, makes it possible to measure photosynthetic activity on Earth. The technique calculates photosynthesis activity in real time and could give the first direct observation of photosynthesis on the planetary scale. The model can be used to survey and compare productivity of different regions.
