Today’s Image of the Day from NASA Earth Observatory shows dust stirred up across the Bodélé Depression, the point of the lowest land elevation in Chad.
It is estimated that dust storms are kicked up in this region 100 days each year. The dust is mobilized by strong winds that funnel through a break in the Tibesti and Ennedi massifs.
According to NASA, Bodélé dust is mostly comprised of particles of quartz and the remains of ancient diatoms – microscopic organisms that originated about 7,000 years ago in Lake Mega Chad.
The image was captured on January 20, 2021 by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-20 spacecraft.
