A dust plume hovered over the borders of Algeria, Mali, and Mauritania on July 8, 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying on NASA’s Terra satellite took this picture the same day. In this image, the dust plume appears as a buff-colored arc. The plume is diffuse, making it difficult to identify the source points for this dust storm.
