   On September 23, 2020, the Moderate Resolution Imaging
   Spectroradiometer (MODIS) on board the Aqua satellite acquired a
   true-color image of dust blowing across Chad.

   The pale beige plumes appear to rise from the Bodele Depression and
   blow to the southwest. Once the floor of Lake Chad, the Bodele
   Depression is now one of the Earth’s most active sources of dust. In
   the mid-1960s, Lake Chad was about the size of Lake Erie. With
   persistent drought in the region and with increasing use of the lake
   for irrigation, the lake has been reduced to only about 5 percent of
   its size. The silt and sediment from the former lake have dried in the
   baking sun, creating copious amounts of fine particles that can be
   easily blown by the wind, sometimes traveling hundreds of miles. The
   dark green area in the lower (southern) section of the image is today’s
   Lake Chad.
