COVID-19 crisis reduces free tropospheric ozone across the northern hemisphere
Throughout spring and summer 2020, ozone stations in the northern extratropics recorded unusually low ozone in the free troposphere. From April to August, and from 1 to 8 kilometers altitude, ozone was on average 7% (≈4 nmol/mol) below the 2000 to 2020 climatological mean. Such low ozone, over sever...

Throughout spring and summer 2020, ozone stations in the northern extratropics recorded unusually low ozone in the free troposphere.

Such low ozone, over several months, and at so many stations, has not been observed in any previous year since at least 2000.
