More than 95% of the ozone on our planet is formed in the tropical stratosphere (at heights of around 20 km) by photochemical processes driven by UV radiation from the sun. The ozone is then transported by air mass transport to mid and high latitudes, where it resides at altitudes between 10 and 50 km. About 10% of the ozone penetrates from the stratosphere to the troposphere (0 to 10 km altitude) during periods of intense stratospheric-tropospheric exchange (storms) and is mostly destroyed there, so that the natural concentration of ozone in the troposphere is generally very low.
