Cover Story: Nationwide lockdowns implemented to combat the spread of COVID-19 have remarkable effects on ambient pollutant emissions and lead to air quality improvement. Such restriction measures in Athens reduced the levels and modulated the spectral aerosol properties, especially during morning traffic hours. The largest reduction during the spring 2020 lockdown period was observed for the absorption coefficient compared to the pre-lockdown period (–39%) and respective periods in previous years (–36%), with a smaller (–21%) decrease for the scattering coefficient. Such changes are mainly expected in urban areas, while at regional/remote sites, optical properties remained unchanged, influenced mainly by meteorology. View this paper
