Herbal Earth: that’s the title of a spectacular collection of vivid new views of the Earth’s vegetation captured over the past year by the Suomi NPP satellite.
NPP is short for National Polar-orbiting Partnership – an Earth science satellite partnership between NASA and the National Oceanic and Atmospheric Administration (NOAA).

Although it’s rather reminiscent of the manmade ‘World at Night’ – its actually the ‘Natural World of Living Green Life.’
The Suomi NPP satellite data were collected with the Visible-Infrared Imager/Radiometer Suite (VIIRS) instrument from April 2012 to April 2013 and used to generate this gallery of images and animations – released by NASA and NOAA on June 19.
Suomi NPP was launched on October 28, 2011 by a Delta II rocket and placed into a sun-synchronous orbit 824 km (512 miles) above the Earth. It orbits Earth about 14 times daily.
The VIIRS instrument measures vegetation changes over time by looking at changes in the visible and near-infrared light reflected by vegetation. The 22-band radiometer sensor can detect subtle differences in greenness.
The data are incorporated into the Normalized Difference Vegetation Index (NDVI) which represents the photosynthetic potential of vegetation.
The NVDI measures and monitors plant growth, vegetation cover and biomass production from the Suomi NPP satellite information.
A quarter of the Earth’s surface is covered by some green vegetation, the remainder is the blue ocean.
