Although 75 percent of the planet is an ocean of blue, the remaining 25 percent of Earth's surface is a dynamic green. Data from the Visible-Infrared Imager/Radiometer Suite (VIIRS) instrument on board the NASA/NOAA Suomi NPP satellite is able to detect these subtle differences in greenness, and is sending extraordinary images back to Earth giving us a clearer picture of vegetation around the world.
