West Africa – February 2nd, 2013

Dust from the Sahara Desert blows off the coast of Mauritania, Senegal, the Gambia and Guinea Bissau (top to bottom, right side of image), towards the Cape Verde islands (upper left quadrant). As the dust appears thickest offshore, the Senegal River (upper right, forming the border between Senegal and Mauritania), the Gambia River (center of coastline) and the Geba River (lower part of coastline, marked by a wide, sediment-filled estuary) can be observed.

West Africa - April 10th, 2012

Golden dust can be seen blowing off the coast of West Africa, over (from top to bottom) Mauritania, Senegal, the Gambia, and Guinea Bissau, towards the Cape Verde Islands (visible in the upper left corner of the full image). The right side of the image also appears covered by a hazy veil, seemingly from a mix of dust and smoke from fires.

Dust off West Africa - March 14th, 2012

Dust from the Sahara Desert continues to blow off the coast of West Africa, over Mauritania, Senegal, the Gambia and Guinea Bissau, and over the Cape Verde islands. Dust has been blowing over this region over the last few days: click here for previous images.

Such dust storms, also known as sand storms, are very common in this arid region. Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface.

Dust off West Africa - March 11th, 2012

Dust plume

Dust blows off the west coast of Africa, and over the Atlantic Ocean. The main image focuses on the dust as it blows westward over  southern Mauritania, Senegal, the Gambia and Guinea Bissau, while the detail image shows an S-shaped plume of dust blowing southwestward and then curving counter-clockwise to the northeast.

The dust has not yet reached as far north as the Bay of Arguin, easily identifiable as a green bay on the coast of Mauritania. The green color is due to the growth of phytoplankton in the bay’s waters.

Vegetation Index from Cap Vert to Bissagos Archipelago, West Africa

Gambia and Senegal - December 23rd, 2011

This FAPAR image shows the vegetation index of Senegal, the Gambia and Guinea-Bissau, along the western coast of Africa. The terrain shows a low vegetation index (light yellow) from Cap Vert (on the peninsula to the left) down to the Gambia River (flowing from near the center to the right edge).

From the Gambia River south to the Casamance River and into Guinea-Bissau, the vegetation index changes to good, as indicated by the green false-coloring. The islands of the Bissagos Archipelago also show a mostly good index of photosynthetic activity.
