Table S1
Stations where lockdown noise reduction was observed; these 185 stations are shown in Figures 1 and 4 and in Figure S1; 'yes' in columnplottedinfig2 indicates that the station was displayed in Figure 2; 'No/double' means that another close by station in the area of interest is used;
Table S2
Stations where lockdown noise reduction was not observed. These 83 stations are also shown in Figure 1;
Table S3
Stations where data gaps, station hardware problems, or longer-term seasonal effects prohibited a conclusion on noise changes. These 69 stations are not plotted in Figure 1.

Movie S1
Movie version of Figure 2 and Figure S1. The time evolution of the amplitude of hiFSAN for each station is shown as bars with variable height. The lockdown dates (LD1) for each country appear on the left side.
