Ozone

Ozone is an everyday part of the atmosphere and is constantly being created and destroyed. Ozone does function as a greenhouse gas, but its strength compared to carbon dioxide is yet to be calculated.

Ozone is created and destroyed by ultraviolet light from the Sun. It is created from oxygen by high energy rays, while low energy rays destroy it.

Some ozone is man-made by various kinds of air pollution, which then reacts in sunlight.
