Saharan Dust Storm
A Saharan dust storm originating in Mali blew off the west coast of Africa on June 6, 2006. The MODIS flying onboard NASA's Terra satellite took this picture the same day.
The dust plumes are the thickest near their points of origin in the east. Although the dust dissipates somewhat as it moves westward, it still remains thick over the Atlantic.
Although partially hidden by the dust storm, the differences of the underlying landscape are still apparent as the sands of the Sahara give way to vegetation in the south.
