Italy - November 17th, 2009

This FAPAR image shows the vegetation index of Italy, including the islands of Sardinia and Sicily, as well as Corsica and parts of coastal Tunisia and Algeria. The vegetation index corresponds to the Fraction of Absorbed Photosynthetically Active Radiation, which provides data on the planet’s climate system.

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 appear blue. Dark red regions correspond to agricultural zones for which there is high photosynthetic activity and therefore vegetation productivity, while yellow to white areas, with the exception of white patches of clouds,  indicate a low degree of photosynthetic activity.

Here, some red areas can be seen on the islands of Sardinia and Sicily, while most of Italy and Corsica appears green with some yellow zones. Algeria and Tunisia show photosynthetic activity near the coast, while the area further south is yellow and white, reflecting the low photosynthetic activity of more arid regions.
