Fires (red dots) blanket southern Sudan (center) in this true-color image from November 5, 2002. The image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite. Moving southward through Sudan, the Sahara Desert (top) gives way to the Sahel (lighter greens), which gives way to tropical savannas (darker greens). Right of center at top, a green line shows vegetation growing along the confines of the White Nile River. At image right is Ethiopia.
