This paper investigates the impact of air quality and climate variability during first wave COVID-19 associated with accelerated transmission lethality in Wuhan China four European metropolises (Milan, Madrid, London, Bucharest). For period 1 January–15 June 2020, including pre-lockdown, lockdown, beyond periods, this study used a synergy situ derived satellite time-series data analyses, investigating daily average inhalable gaseous pollutants ozone (O3), nitrogen dioxide (NO2), particulate matter two size fractions (PM2.5 PM10) together Air Quality Index (AQI), total Aerosol Optical Depth (AOD) at 550 nm, variables (air temperature 2 m height, relative humidity, wind speed, Planetary Boundary Layer height). Applied statistical methods cross-correlation tests involving multiple datasets main (inhalable PM2.5 PM10 NO2), AQI, aerosol loading AOD revealed direct positive correlation spread severity COVID-19. Like other cities worldwide, first-wave due to implemented restrictions on human-related emissions, there was significant decrease most pollutant concentrations (PM2.5, PM10, but high increase ground-level O3 all selected metropolises. Also, found negative correlations new cases (DNCs) surface level, PBL heights, speed intensity humidity. The findings highlight differential impacts pandemic lockdowns investigated
