Dust Plume over the Sahara
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
The dust plume formed a giant, southward-swooping arc extending from Algeria to Western Sahara. Source points for the plume are not obvious in this image, but dust storms often blow from east to west in this region, sometimes carrying dust over the Atlantic Ocean. Sand seas carpet large parts of Algeria, Mali, and Mauritania, and this dust storm likely picked up additional material as it blew across the Sahara.
