Most of the ozone production occurs in the tropical upper stratosphere and mesosphere. The total mass of ozone produced per day over the globe is about 400 million metric tons. The global mass of ozone is relatively constant at about 3 billion metric tons, meaning the Sun produces about 12% of the ozone layer each day. [1]
This series of reactions creates a null cycle, in which there is no net production or loss of any species involved. Since O( 3 P) is very reactive and O 2 is abundant, O( 3 P) can be assumed to be in steady state , and thus an equation linking the concentrations of the species involved can be derived, giving the Leighton relationship: [ 2 ] [ 3 ]
