Smoke and Dust Creating Haze Over West Africa

Chad – February 2nd, 2013

Dust blowing south from the Sahara Desert mixes with smoke, creating a haze in the air over Ghana, Benin, Togo and Nigeria, in the southern part of West Africa. The coastline is barely visible through the haze near the bottom edge of the image.

Dust Over Niger and Nigeria

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.

Saharan Dust Around Lake Chad

Chad – January 7th, 2013

Dust blows southward from the Sahara Desert and Bodélé Depression over Chad and Nigeria, but mostly avoids Lake Chad (top center). Due to the annual cycle in winds over the Sahara, the winter Saharan dust sources are different from the summer sources. In the summer, dust fluxes reaching the Tropical Atlantic shore originate mainly from the northwest and central-west parts of the Sahara. During winter, strong surface winds (the Harmattan winds) occur along the southern border of the Sahara, activating sources on the border of the Sahel, notably the Bodélé depression in Northern Chad.

Benue River and Dust by Nigeria-Cameroon Border

Nigeria and Cameroon – December 25th, 2012

Dust from the Sahara Desert can be seen in the air near the border between Nigeria and Cameroon. Visible crossing the image from the center to the left edge is the Benue River, the major tributary of the Niger River, which is visible parallel to the left edge.

The Benue is approximately 1,400 km long. It rises in the Adamawa Plateau of northern Cameroon, from where it flows west, and through the town of Garoua and Lagdo Reservoir, into Nigeria south of the Mandara mountains, and through Jimeta, Ibi and Makurdi before meeting the Niger at Lokoja. At the point of confluence the Benue exceeds the Niger by volume (mean discharge before 1960: 3400 m³/s vs. 2500 m³/s).

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).
