   Dust over Arabian Sea

   Dust plumes from Iran, Afghanistan, and Pakistan streamed over the
   Arabian Sea in late January 2021, creating a thick blanket of dust the
   hid the surface of the water from view. The Moderate Resolution Imaging
   Spectroradiometer (MODIS) on board NASA’s Terra satellite acquired a
   true-color image of the scene on January 23.

   On January 22, strong winds lifted copious amount of light tan dust and
   sand from several locations in all three countries. The southward
   blowing winds began to move the dust over the Arabian Sea on that day.
   By the next day, a huge blanket of dust stretched more than 600 miles
   (965 km) southward off the coast, with the western edge reaching Oman.
   Most of the skies over Oman remained dust-free, however. Additional
   dust from Pakistan blew over the Gulf of Oman (located in the west).

   Dust plumes often arise from the dry lakebed sediments along the border
   between Iran and Afghanistan. Dust also frequently arises from the sand
   seas occurring over much of western Pakistan and from the sandy desert
   that stretches for hundreds of kilometers along the Pakistan-India
   border. These all appear to be sources for this particular dust storm.
