How is ozone produced in the upper atmosphere
WebAgain, notice that HOx (OH + HO2) is neither produced nor destroyed by this cycle, but merely acts as a catalyst for converting two molecules of ozone into three molecules of O2.The importance of this reaction is that it does not require free O atoms for the reaction. Two other reactions are important for OX loss in the upper stratosphere. The first one … WebAs was already mentioned, ozone that occurs in the upper reaches of the atmosphere interacts with ultraviolet radiation coming from the sun. This interaction keeps most of that UV light from hitting the surface of the Earth, where it would cause serious problems for the plants and animals living there.
