Tropospheric ozone depletion events

Tropospheric ozone depletion events are phenomena that reduce the concentration of ozone in the Earth's lower atmosphere. Ozone (O3) is a trace gas which has been of concern because of its unique dual role in different layers of the atmosphere. Apart from absorbing UV-B radiation and converting solar energy into heat in the stratosphere, ozone in the troposphere provides greenhouse effect and controls the oxidation capacity of the atmosphere.
