The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) viewed this large
dust storm over Iran, Afghanistan, and Pakistan today (May 18, 2001).
The dust (tan pixels) appears to be lifted from the Khash and Margow
Deserts of Southwestern Afghanistan, carried southward along the Iran
border and then angling eastward into Pakistan.
The various shades of brown reflect a varied landscape containing
expanses of flat open desert, dry lake beds, dune fields, and mountain
ranges. The large golden-brown, stingray-shaped region toward the upper
right corner of this image is a sandy desert known in Afghanistan as
Rigestan. Roughly 480 km (300 miles) due west (left) of Rigestan is the
Iranian Lut Desert. The darker brown splotches immediately to the south
(below) of Rigestan are Pakistan's Chagai Hills, which mark the border
between the two countries. The Siahan Mountains can be seen about 240
km (150 miles) due south of the Chagai Hills.
