Atacama Desert

November 14, 2012
The southern Atacama Desert is pictured in this Envisat image, with the border of Chile (west) and Argentina (east) running down the middle. The Atacama is believed to be the driest desert in the world, and the lack of cloud cover in this image highlights the dry climate. This image was acquired by Envisat’s MERIS instrument on 4 March 2012.
