Sources of Aerosols
Aerosols can occur in nature, but they can also originate from human activity. These animations provide 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 Earth's atmosphere, and finally disappear by creating sediment or raining out.    This animation shows the different sources of aerosols, how they mix in the Earth's atmosphere, and finally disappear by creating sediment or raining out.

The different sources of aerosols mix on the earth's surface. This animation shows some of the major sources of the different types of aerosols: India (urban haze), desert dust (Northern Africa), biomass burning (California, US), and ocean spray (Pacific Ocean).    The different sources of aerosols mix on the earth's surface.

This is the opening scene in a larger animation showing the sources of various types of aerosols. The smog emitted from the city is exaggerated so that the viewer understands that aerosols are coming from the city. The camera follows the path of the aerosol cloud into the sky where it rests on a cloud (aerosols being added to the cloud).    This is the opening scene in a larger animation showing the sources of various types of aerosols.

Oceans are a third source of aerosols. The camera observes sea salt spray aerosols rising into the sky, follows the path downwards to the source (the rocky ocean), and back up into the sky where the aerosols are gathering in a cloud.    Oceans are a third source of aerosols.
