Brazil - April 27th, 2010

These side-by-side MERIS (left) and FAPAR (right) images offer a comparative look at the eastern coast of Brazil, near the city of Rio de Janeiro. The former makes it possible to observe the true appearance of the region, while the latter provides a false-color view of the area’s vegetation index.

In the MERIS image, Rio de Janeiro (bottom) appears as a grey area along the western shores of Guanabara Bay (Baia de Guanabara), while in the FAPAR image the city appears yellow due to its low index of photosynthetic activity. Most of the rest of the FAPAR image appears dark green to red, indicating a good to high vegetation index.
