Dust Plumes off the West Coast of Africa

Dust Plumes off the West Coast of Africa

Dust and clouds mingled over the Atlantic Ocean on July 2, 2009, spreading more than a thousand kilometers west of the African coast. The dust was likely a remnant of plumes that had blown off the African coast the previous day. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this natural-color picture on July 2. Thin but discernible dust plumes form a massive counter-clockwise arc west of Western Sahara and Mauritania. A pocket of thick dust appears to have collected southwest of Cape Verde, immediately south of a large cloud bank. The large version of this image has a resolution of 1 kilometer.
