Despite its rather arid interior zones, the coast of Australia’s Northern Territory shows a higher vegetation index in this FAPAR image. FAPAR, or Fraction of Absorbed Photosynthetically Active Radiation, corresponds to the vegetation index of a given area.

In FAPAR images, the color spectrum over land runs from red (1.0), to green, to yellow and white (0.0), while bodies of water,  such as Lake Argyle (left), appear blue.

This image contains no areas of high photosynthetic activity, although the green areas along the coast and on Melville Island (above) indicate mid-range values. Moving southward towards Australia’s arid interior, the values decrease from 0.2 (yellow) to 0.0 (white), indicating little to no photosynthetic activity.
