On January 11, 2013, a dust storm struck Iran’s Dasht-e Kavir,
or Kavir Desert. The Moderate Resolution Imaging
Spectroradiometer (MODIS)
on NASA’s Terra satellite
captured this natural-color image the same day. Dust plumes blew eastward, many
of them arising from discrete source points.
In eastern Iran, dust plumes blew southward, passing over the diverse
terrain of
the Dasht-e Lut in the southeastern part of the country. (The dust plumes in
eastern Iran can be seen in the high-resolution
image.)
Situated on the Iranian Plateau, southeast of Tehran, Dasht-e
Kavir is known as the Great Salt Desert. The plateau’s landscapes include
gravel plains, sand dunes, small streams, and salt flats. Dasht-e Kavir
typically sees less than 100 millimeters (4 inches) of precipitation a year,
and the region has no major water bodies. It is considered one
of the hottest places on Earth. This
area lies within a broad band of prolific dust-producing land stretching from
the Sahara Desert in the west to the Gobi Desert in the east.
