South America - January 31st, 2011

This FAPAR image shows the vegetation index of southwestern South America, stretching from the border of Chile, Bolivia, Paraguay and Argentina in this thumbnail image, to Chilean and Argentine Patagonia in lower portion of the full image.

The land in northern Chile and western Bolivia is quite arid, and thus shows a low vegetation index (very light yellow). The terrain in the Andes Mountains in the upper part of the image shows a good to high (green to rusty red) index. The land to the east in southeastern Bolivia, Paraguay and northern Argentina shows generally good photosynthetic activity.

In the full image, however, the higher levels to the east and the lower levels to the west “switch sides” as one moves southward. Chilean Patagonia, west, shows a generally good index while Argentina Patagonia, east, shows a generally low one.
