Fig. 3 a Average diurnal concentrations of PM2.5 prior to and after a lockdown in 2020 (light area) and comparison for the same period in 2019 (dark area). b Average monthly concentrations of PM2.5 in 2021, 2020, and 2019. Data from air pollution traffic monitoring station (TS-W), Warsaw, Poland. B-spline curve (basis spline function) was applied for the smoothness of experimental data
