- A dust storm blew through part of eastern Chad on June 11, 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard NASA’s Terra satellite captured this image of the storm as it blew toward Lake Chad. In this image, the dust appears as a wisp of pale beige set against a darker tan background. Lake Chad, near the border with Nigeria and Cameroon, is barely visible in this image, although it has been easily discernible in other satellite images.
