Aerosols can occur in nature, but they can also originate from human activity. This animation provides an introduction to four of the varied sources of atmospheric aerosols: cities, forest fires, the ocean, and deserts. This animation shows the different sources of aerosols, how they mix in the Earths atmosphere, and finally disappear by creating sediment or raining out. Of particular interest is the role of the oceans: salts from the sea spray serve as condensation nuclei. In this animation, sea salt spray aerosols rise into the sky, follows the path downwards to the source (the ocean), and back up into the sky where the aerosols gather in a cloud.
