A dust storm swept across the Sahara Desert on May 10, 2006, moving dust across Niger, Nigeria, Cameroon, and Chad. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard the Terra satellite took this picture the same day. In this image, the dust appears as a pale beige plume that sweeps westward over the desert. White clouds dot the skies around the fringes of the storm.
Acquired April 22, 2010, this natural-color image shows a dust plume spanning hundreds of kilometers in western Africa. A wall of dust appears to advance toward the southeast in Burkina Faso and Niger.
