This FAPAR image shows the vegetation index of parts of Portugal (above left), Spain (above right) and Morocco (below), across the Strait of Gibraltar. The index ranges from good (green false-coloring) to low (yellow false-coloring).
Photosynthetic activity is higher to the west, in Portugal, and becomes progressively lower as one moves eastward towards Spain’s Meseta Central. It becomes higher once again in extreme southern Spain just north of the Strait of Gibraltar. The index in the small area of Morocco that is visible also appears higher to the west and lower to the east.
