West Africa – June 19th, 2013

West of Western Sahara, Mauritania and Senegal, off the coast of West Africa, is an atmospheric phenomenon known as Kármán Vortex Streets. These parallel rows of oppositely spinning vortices, caused by the unsteady separation of flow of a fluid around blunt bodies, can be seen trailing off the Canary Islands (above) and off the Cape Verde islands (below). Some dust can also be seen spreading off the coast of Mauritania.

A plume of dust spreads westward, off the coast of West Africa by the Mauritania-Senegal border (marked by the Senegal River, right center). The plume extends west-southwestward, blowing far over the Cape Verde Islands.

West Africa – May 25th, 2013

Dust from the Sahara Desert blows westward off the coast of West Africa. The dust is thickest around the border between Mauritania (above) and Senegal (below), with plumes visible just north of the Senegal River (center) and the Cap-Vert peninsula, a rocky promontory extending west from the main sandy areas of Senegal on which the capital city of Dakar is located.

Smoke from Agricultural Fires in West Africa – April 4th, 2013

West Africa – April 2nd, 2013

While sun glint highlights rivers along the coast of Guinea and Sierra Leone, fires furthern inland in West Africa create a haze that covers much of the region. Many of the fires have been active since late March, and are clustered in the green lands of Sierra Leone, while others dot the landscape of Guinea and Liberia. A few blazes are present in southwest Mali and Côte d’Ivoire, as well.

While the source of these fires cannot be discerned in the satellite imagery, this pattern at this time of year in this region is typical of agricultural fires. Farmers deliberately set such blazes in order to clear land, bring nutrients into the soil, prepare fields for planting, and renew pastureland. The smoke from the fires, however, create air pollution, which can cause health problems both in humans and livestock both close to, and far from, the source.

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.
