This animation is a global visualization of the light released by plants during photosynthesis. It”s based on the first year of solar-induced fluorescence (SIF) measurements (Sept. 2014 – Sept. 2015) from NASA’s Orbiting Carbon Observatory-2 mission.
Each map represents a 16-day cycle and shows average concentrations of SIF. The measurements are reported in radiance (a measure of the amount of light); more light is shown as more green. The seasonal shifts of photosynthesis and the large agricultural areas of the world are apparent.
