Abstract Ozone is one of the most important trace gas in our atmostphere. It is chemically active and its distribution is determined by formation and loss processes. While numerous destruction cycles have been studied in detail, its formation has been assumed to be well understood.
Enrichments decrease toward lower temperatures and higher pressures.
Since ozone is involved in many chemical processes in the atmosphere, its isotope signature can be transferred to other minor species to become an important tracer for transport and chemical reactions.
