Appears in 3 processs and 9 steps. Everything below is linked: open a process to see it in context.
Top processes
- Start: Tropospheric ozone, NOx-VOC chemistry and aerosol nucleation
- End: Tropospheric ozone, NOx-VOC chemistry and aerosol nucleation
- 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
- and 3 more in this process
- OH is recycled by nitrogen oxides and replenished as the tropics widen, so its level stayed roughly steady from 1980 to 2015 despite more methane
- Catalytic cycles of chlorine, bromine, nitrogen and hydrogen oxides destroy ozone: one chlorine atom can remove thousands of ozone molecules, and gas-phase chlo
