The thin plume of dust that hung over the Arabian Sea on October 15, 2008, intensified as the day wore on. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired this image a little over three hours after MODIS on the Terra satellite captured the same plume.
In this photo-like image, the dust is lighter in color and more opaque than the earlier plume. Larger puffs of dust blow southward off the coasts of Iran and Pakistan. All the plumes follow the same general direction, toward the southwest.
