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.

Guinea Bissau and Guinea – February 3rd, 2013

A thick haze hangs over Guinea Bissau, Guineau, Sierra Leone and Liberia (along coast from top to bottom), in West Africa. The haze is likely a combination of smoke from agricultural fires and dust from the Sahara Desert. Visible through the smoke are sediments spilling forth from the mouth of the Geba River, in Guinea Bissau (upper left corner).

West Africa - April 6th, 2012

Smoke blows off the coast of West Africa near the border between Guinea and Sierra Leone. Extremely arid conditions have been causing problems with wildfires and dust storms in the region over the last month (click here for previous images). Visible further up the coast are sediments pouring into the Atlantic Ocean from the Geba and other rivers in Guinea Bissau.

Dust Off West Coast of Africa - March 5th, 2010

Dust Off West Coast of Africa - March 5th, 2010

Dust blows off the coast of Africa from a dust storm that was affecting the continent from its north to west coast at the time the image was taken (click here for previous article). Here, the dust blows over the countries of Senegal, the Gambia, Guinea-Bissau, Guinea and Sierra Leone (following the shoreline from top to bottom).

Below the dust, sediments spill from the mouth of the Geba River into the Atlantic Ocean, off the coast of Guinea-Bissau. The river rises in Guinea and passes through Senegal before reaching Guinea-Bissau and the coast. It is about 340 miles in total length.

Dust Across Africa to West Coast - March 21st, 2010

A massive dust storm has been sweeping across the southern Sahara Desert, bringing dust from the Red Sea to the west coast of Africa.

The main image focuses on the dust blowing over the west coast, shrouding nations including Western Sahara, Mauritania, Senegal, the Gambia, Guinea Bissau, Guinea and Sierra Leone (from top to bottom, following the shoreline).

The other image shows the dust clouding the skies over countries further east, from southern Algeria across inland Mauritania, through Mali, to northern Côte d’Ivoire.
