Dust in Northern Africa (Algeria, Tunisia, Libya)

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.
