Niger and Mali – June 1st, 2013

A close inspection of this image reveals yellow dust blowing about in the air over Niger (right) and Mali (left). Mostly unaffected by the dust due to their high altitude are the Aïr Mountains. Lying in the midst of the Sahara Desert, with an average altitude between 500 and 900 m (1,600 and 3,000 ft), the mountains form an island of Sahel climate which supports a wide variety of life.

Chad – March 23rd, 2013

Dust blows across the Sahara Desert, creating a thin veil over Lake Chad (below) and south of the Aïr Mountains, a triangular massif in northern Niger (left edge). While the dust cross the southernmost part of the Aïr range, it does not affect the Tibesti Mountains, another volcanic range in Chad, to the northeast.

Chad – February 1st, 2013

Dust from the Sahara Desert veils the skies over Chad, Niger and Nigeria (counter-clockwise from upper right). The dust is less thick in Chad and by Lake Chad, where the three countries share borders. The dust also clears in northern Niger, where the Aïr Mountains are visible upon opening the full image.

Niger – December 25th, 2012

Dust in Niger blows around the Aïr Mountains, a plateau that forms an island of Sahel climate amidst the Sahara Desert sands and supports a wide variety of life. While the dust here appears to be carried northward, Niger’s neighbor to the south, Nigeria, is experiencing growing desertification as rising temperatures allow the edge of the Sahara Desert to creep closer to the country.

Plumes of Dust by Lake Chad and Aïr Mountains, Chad and Niger – December 26th, 2012

Niger and Chad – December 24th, 2012

Three plumes of dust from the Sahara Desert can be seen blowing west-southwestward in this image of West Africa. Near the center, northeast of Lake Chad, are two light, parallel plumes originating from the Bodélé Depression, in Chad. Near the left edge, south of the Aïr Mountains, in Niger, is the last plume of dust, darker tan in color than the other two and apparently carrying fewer particles. In the lower part of the full image, smoke and fires can be seen across the Central Africa Republic, Cameroon and Nigeria (right to left).
