African dust storm. Ultraviolet (UV) satellite image of aerosols from airborne dust and smoke (red, orange, yellow, green). The Sahara desert and Arabian Peninsula are the source of dust that spreads westwards across the Atlantic Ocean towards Central and North America. Smoke from biomass burning in Southern Africa and South America also spreads west. Aerosols cause climate change by reflecting sunlight and encouraging cloud formation which cools the land beneath. Dust deposited into the oceans increases mineral content and encourages phytoplankton growth. Image taken by NASA's Total Ozone Mapping Spectrometer (TOMS) on August 1987.
