Sri Lanka- December 31st, 2011

This FAPAR image shows the vegetation index of Sri Lanka. The Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) is 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 estimate the assimilation of carbon dioxide in vegetation.

Photosynthetic activity is mostly good across the island, as shown by the predominately green false-coloring. Some areas of high activity can be observed; these appear rusty red in color, and are located mostly near the southeastern coast, central southern coast, and central west coast. Areas of low activity appear yellow; very few such areas are visible, but a few can be observed towards the center of the island nation and in one part of the western coastline.
