Tropospheric ozone is produced through the interaction of heat and UV light, with nitrogen oxides and carbon-containing compounds. Ozone is found in two different layers of the atmosphere, the troposphere and the stratosphere. The Stratospheric ozone is a good ozone, while Tropospheric ozone is a bad ozone.
Only 10% of the ozone in the earth's atmosphere is found in the troposphere. Ozone in the troposphere is one of the greenhouse gases.
