Another plume of dust passed over China on April 22, 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard NASA’s Aqua satellite took this picture the same day. In this image, the dust plume appears as a band of tan that arcs across the scene from lower left toward the center right. South of the dust plume is a bank of clouds. Some of the grayish material north of the plume could be pollution.
