Tropospheric ozone between January 2018 and January 2019 measured by the Copernicus Sentinel-5P mission. Ozone lower down in the atmosphere – in the troposphere – is an air pollutant and a greenhouse gas contributing to global warming. It is difficult to measure because of its short lifespan and because concentrations can vary hugely from place to place. The unprecedented spatial resolution offered by Copernicus Sentinel-5P’s Tropomi instrument means that the complex relationship between tropospheric ozone and climate can be better understood.
