“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.”
As displayed in this fabulous video, NOAA has produced in-depth information about the Earth’s dynamic vegetation layers. This is a great example of how remote sensing data can enhance our understanding of the planet; additionally it is packaged in a very user-friendly format for a wide ranges of audiences. For great static images of this data layer, National Geographic has produced this great gallery.
