   An expansive Saharan dust storm covered much of northwestern Africa in
   late April 2022. The Moderate Resolution Imaging Spectroradiometer
   (MODIS) on board NASA’s Terra satellite acquired a true-color image of
   the sandy scene on April 21. At that time, pink-tinted clouds of sand
   and dust stretched over more than 1,500 miles (2,414 km) from the
   Atlantic Ocean to the Mediterranean Sea. Although only Algeria, Libya,
   and Tunisia are captured in this image, the vast blanket of dust also
   covered parts of Morocco, Western Sahara, and Mauritania.

   There is not a single point source that is responsible for this dust
   storm, rather strong winds blowing across a large part of the Sahara
   Desert has lofted sand and dust aloft over a long stretch of
   northwestern Africa. A thick area of dust near the lower left
   (southeast) section of the image sits over Erg Chech in Algeria, one of
   many sand seas located in Algeria, Mauritania, and Mali. These sandy
   deserts provide ample material for dust storms.
