Dust Storm off West Africa

July 20, 2012
Dust poured off the coast of Africa and over the Atlantic Ocean on in mid-July, 2012. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured this true-color image on July 11, 2012 at 14:45 UTC (2:45 local time in Mauritania).

A broad plume of dust blows to the southeast, crossing both Western Sahara (north) and Mauritania (center). As it passes over the Atlantic Ocean, the plume appears to broaden and thin as it covers the Cape Verde Islands. The air over Senegal, to the south, remains relatively clear.
