Ozone in the stratosphere is made when high‑energy ultraviolet (UV) light splits molecular oxygen (O2) into two oxygen atoms; those free O atoms then collide with O2 molecules (with a third molecule M carrying off excess energy) to form ozone (O3). This set of reactions, called the Chapman mechanism, produces a layer of ozone that absorbs much of the Sun’s UV radiation; catalytic cycles driven by species like NOx and ClOx can also destroy ozone and influence its concentration.
