In late March 2008, Saharan dust blew off the west coast of Africa over the Atlantic Ocean. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite took this picture of the blowing dust on March 28, 2008. In this image, the almost-opaque dust storm blows in a slightly counter-clockwise direction toward the southwest. Rather than appearing as a series of distinct plumes, this dust storm appears as one large plume hundreds of kilometers long.
This event continued dust storm activity in the Sahara desert. Just two days earlier, Saharan dust blew northward over the Mediterranean Sea.
Saharan dust hovered over the Atlantic for several days in mid-January 2008. This image shows two different areas of dust plume activity. Immediately off the coasts of Western Sahara and Mauritania, a series of tan dust plumes blow in predominantly straight lines toward the northwest. Farther west, a large, diffuse plume of dust hangs over the Atlantic Ocean
