Top processes
- Sunlight splits NO2 to make ozone; OH-driven oxidation of VOCs and CO makes peroxy radicals that turn NO back to NO2 without consuming ozone, so ozone accumulat
- Which ingredient limits ozone production?
- NOx-limited (most of the remote and rural troposphere): more NOx means more ozone (about 80%, estimate)

- Cutting ozone-depleting gases under the Montreal Protocol lets ozone return to 1980 levels around 2040 globally, 2045 in the Arctic and 2066 over Antarctica
- Solar ultraviolet splits oxygen molecules and the freed atoms join O2 to make ozone; about 90% of Earth's ozone sits in the stratosphere
- Catalytic cycles of chlorine, bromine, nitrogen and hydrogen oxides destroy ozone: one chlorine atom can remove thousands of ozone molecules, and gas-phase chlo
