Watching plant photosynthesis...from space

(University of Sydney) University of Sydney and NASA have developed a revolutionary technique to image plant photosynthesis using satellite-based remote-sensing, with potential applications in climate change monitoring. The uptake of carbon dioxide by leaves and its conversion to sugars by photosynthesis, referred to as gross primary production (GPP), is the fundamental basis of life on Earth and its quantification is vital for research on terrestrial carbon cycle dynamics.
