United Kingdom and France - January 6th, 2012

This FAPAR image shows the vegetation index of parts of England (above) and France (below). The two countries are separated by the English Channel. The city of London appears as a large, circular grey area near the southeastern coast of England.

FAPAR stands for Fraction of Absorbed Photosynthetically Active Radiation, the fraction of the incoming solar radiation in the Photosynthetically Active Radiation spectral region that is absorbed by a photosynthetic organism. This biophysical variable is directly related to the primary productivity of photosynthesis and some models use it to indicate the state and evolution of the vegetation cover. Here, the vegetation index is generally good (green) across the region, with a few areas of low activity (yellow) visible. In the full image, areas of high activity (rusty red) can be seen in France.
