Solar-induced fluorescence, a plant process that occurs during photosynthesis, from Aug. through Oct. 2014 as measured by NASA's Orbiting Carbon Observatory-2.
This map shows solar-induced fluorescence, a plant process that occurs during photosynthesis, from Aug. through Oct. 2014 as measured by NASA’s Orbiting Carbon Observatory-2. This period is springtime in the Southern Hemisphere and fall in the Northern Hemisphere. Photosynthesis is highest over the tropical forests of the Southern Hemisphere but still occurs in much of the U.S. Grain Belt. The northern forests have shut down for the winter.
