Using measurements from the Copernicus Sentinel-5P satellite, the animation shows changes in the ozone hole over Antarctica between September and October 2018.
Launched in October 2017, Sentinel-5P is the first Copernicus mission dedicated to monitoring our atmosphere. The satellite carries the state-of-the-art Tropomi instrument to map a multitude of trace gases that affect the air we breathe and our climate. As well as measuring ozone, this new mission also measures gases such as nitrogen dioxide, formaldehyde, sulphur dioxide, methane, carbon monoxide, and aerosols.
