African Dust Crossing the Atlantic   This animation shows the
trajectory of aerosols as they cross the Atlantic Ocean from
Africa to the Caribbean. Comprised of Total Ozone Mapping
Spectrometer (TOMS) aerosol index images collected from June
12-21, 2001, it shows a cloud of Saharan dust caught up in
northeast trade winds crossing the ocean and eventually raining
down upon the Caribbean, carrying with it minerals, microbes,
fungi, and bacteria. The movie runs in a continuous loop.  This
