ABSTRACT
COVID-19 pandemic forced many countries to adopt lockdown measures, temporarily closing factories, diminish maritime traffic and reducing the mobility of people in the cities. Analysis from the Tropospheric Monitoring Instrument (TROPOMI) on board Europe's Sentinel-5P and Copernicus Atmosphere Monitoring Service (CAMS), for the first wave of COVID-19 in 2020, have shown a substantial improvement in air quality. More specifically, since lockdown until the end of April, Lisbon and Porto were at their lowest PM10 levels in 2 years, while Madrid had a significant drop with values considerably below 2018 levels but still close to 2019 values. In terms of NO2 levels, Lisbon had an historical minimum of the last 2 years during most of April 2020 and Madrid had 2-year lowest level since lockdown. Finally, the commercial port of Ponta Delgada (São Miguel, Azores) had a decrease in cruise ship calls during the pandemic, which reduced the number of daily cases with significant NO2 concentrations, comparing to 2019. © 2021 IEEE
