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

9.2N 9.1W

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.

Smoke and Dust Over West Africa From Guinea Bissau to Liberia – February 8th, 2013

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).

Dust and Smoke Over West Africa - March 18th, 2012

Dust and smoke mingle in the lower part of this image of West Africa, particularly in the lower right quadrant. Fires in this region, particularly near the border of Liberia, Côte d’Ivoire and Guinea, have been releasing a thick cloud of smoke over the last few days (click here for previous images of the fires).

The region has also be plagued by a dust storm (click here for previous images). While a veil of dust is visible over much of the image, a thicker plume can be seen blowing off the coast of Senegal in the lower left quadrant.

Dust off West Africa - March 14th, 2012

Dust from the Sahara Desert has been blowing off the western coast of the African continent over the last few days, veiling the skies over countries such as Mauritania, Senegal, the Gambia and Guinea Bissau, and stretching towards the Cape Verde islands (click here for previous images).

Here, the dust is blowing in a southwesterly direction, partially obscuring the mouths of rivers such as the Geba River, in Guinea Bissau (near image center). Visible near the border of Liberia, Côte d’Ivoire and Guinea, by the right edge of the image in the lower right quadrant, are a series of fires, releasing a cloud of smoke that mingles with the dust.

Vegetation Index of Liberia and Ivory Coast

Ivory Coast - December 30th, 2011

This FAPAR image shows the vegetation index of the Ivory Coast (right) and Liberia (left), in western Africa. The vegetation index is lower to the north, as indicated by the yellow false-coloring, as one nears the Sahara Desert.

It becomes higher to the south, however, as one nears the coastline. Along the coastal plains, it is generally good, as evidenced by the green false-coloring, although some patches of high activity (rusty red) can be observed, particularly in Liberia.
