Dust continued blowing off the coast of eastern Africa and over the Red Sea on July 13, 2011. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image the same day.
As on the previous day, the thickest dust blew off the coast of Sudan, following a clockwise arc over the Red Sea, but stopping short of the Arabian Peninsula. To the north, a much thinner, fainter plume followed a similar path. To the south, a veil of dust spanned the Red Sea.
This true-color image shows dust plumes blowing off the Sudanese coast and over the Red Sea on July 9, 2009. The thickest dust plume blows toward the northeast, but thinner dust plumes blow toward the southeast, just missing the coast of Saudi Arabia.
