A gaseous molecule that contains three oxygen atoms (O3), instead of the usual two (O2). Ozone can exist either high in the atmosphere (stratosphere), where it shields the Earth against harmful ultraviolet rays from the sun, or close to the ground (troposhere), where it is the main component of smog.
