The Saharan dust plume that departed Africa on June 22, 2007, was hovering over the Caribbean Sea five days later. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this picture on June 27, 2007. In this image, the dust appears as a very thin veil of brownish haze over the ocean.
