Dramatic Satellite Images Show Air Pollution Remains Low as Europeans Stay at Home

Further analyses are showing the continued low levels of nitrogen dioxide concentrations across Europe – coinciding with lockdown measures implemented to stop the spread of the coronavirus. New data from the Copernicus Sentinel-5P satellite, from the European Union Copernicus program, show some cities seeing levels fall by 45—50% compared to the same period last year.


These images, using data from the Copernicus Sentinel-5P satellite, show the average nitrogen dioxide concentrations from  March 13 to April 13, 2020, compared to the March-April averaged concentrations from 2019. The percentage decrease is derived over selected cities in Europe and has an uncertainty of around 15% owing to weather differences between 2019 and 2020.
