Top processes
- Precursors enter the troposphere: lightning makes about 5 Tg N/yr of NOx, plants emit about 1,000 Tg/yr of volatile organic compounds (half isoprene), and fuel
- 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
- NOx-limited (most of the remote and rural troposphere): more NOx means more ozone (about 80%, estimate)
