Image of a #dust storm captured by #MODIS in 2002.

The African countries of #Sudan (top left), #Ethiopia (bottom left), with #Eritrea nestled between them along the western coast of the Red Sea. On image right are Saudi Arabia (top) and #Yemen (bottom) on the Arabian Peninsula. Overlooking the Red Sea, a long escarpment runs along the western edge of the Arabian Peninsula, and in this image appears to be blocking the full eastward expansion of the dust storm.
