Green Tour of Earth (video)

Although 75% of the planet is a relatively unchanging ocean of blue, the remaining 25% of Earth’s surface is a dynamic green. Data from the NASA/NOAA Suomi NPP satellite is able to detect these subtle differences in greenness.

The resources on this page highlight our ever-changing planet, using highly detailed vegetation index data from the satellite, developed by scientists at NOAA. The darkest green areas are the lushest in vegetation, while the pale colors are sparse in vegetation cover either due to snow, drought, rock, or urban areas. Satellite data from April 2012 to April 2013 was used to generate these animations and images.

Images crafted from a year’s worth of data collected by the Suomi NPP satellite provide a vivid depiction of worldwide vegetation. Suomi NPP, short for National Polar-orbiting Partnership, is a partnership between NASA and the National Oceanic and Atmospheric Administration.

The images show the difference between green and arid areas of Earth as seen in data from the Visible-Infrared Imager/Radiometer Suite, or VIIRS, instrument aboard Suomi NPP. VIIRS detects changes in the reflection of light, producing images that measure vegetation changes over time.
