How is Ozone Formed?

Basic purpose of this lecture is to present on how is Ozone Formed. UV radiation strikes the O2 molecule and splits it, atomic oxygen associates itself with another O2 molecule – simplistic version. Ozone also has substantial variability on smaller time scale. Stratospheric ozone is formed naturally by chemical reactions involving solar ultraviolet radiation (sunlight) and oxygen molecules, which make up 21% of the atmosphere.
