The air over central Africa was bright with blowing dust (top) and what is probably a mixture of dust and smoke (left center) when this image of the area around Lake Chad (large green area above image center) was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite was captured on November 28, 2004. In addition to the dust storm in the Bodele Depression north of Lake Chad, numerous fires (locations marked in red) burning in the Sahel and savannas of Nigeria, Cameroon, Chad, and the Central Africa Republic were contributing to the atmospheric haze.

The Bodele Depression in Central Africa is probably the single largest source of wind-blown dust in the world. Blowing clouds of dust have risen up from the depression periodically since Novemember 2004. This image is from the Terra MODIS sensor on January 6, 2005.
