A dust storm was blowing large quantities of dust out over the Persian Gulf and Arabian Sea on Saturday, December 13, 2003. In this true-color scene, acquired by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS), the dust storm (light brown pixels) can be seen extending from the the Arabian Peninsula (left) eastward over the Persian Gulf and the Gulf of Oman toward the Arabian Sea. Parts of southern Afghanistan and much of Pakistan are also covered by airborne dust. Additional images of the event were captured by the Moderate Resolution Imaging Spectroradiometer on December 14, 2003.

Farther to the east, over northwestern India, there appears to be an extensive plume of another aerosol type. The grayish color of the haze there suggests it is of human origin.
