Abstract: This paper discusses how the efforts of authorities to limit the spread of COVID-19 have led to restrictions in people’s mobility with significant impacts on air traffic operations worldwide. Zurich airport has experienced a drop of 91 per cent in aircraft movements from February to April 2020. The decrease in activity has led to a decrease in local emissions of 83 per cent for NOx, while NO2 concentrations at and around the airport decreased by only 50 per cent. Ultrafine particle numbers show similar values. The analysis further took into account the change in regional road traffic and the meteorology for comparable periods in 2019 and 2020, before and during the crisis.
