A Google Earth Engine App (prototype) to compare European countries NO2 Median changes during the Corona lockdown with the previous year.
TL;DR Europe’s air pollution decreases at weekends and rises again during the working week. The Netherlands is the country with the highest proportion of Nitrogen Dioxide (NO2) in the air - during working days. A Car-Free-Day Saturday in Spain and Portugal did not show a significant improvement in NO2 values compared to other “normal” Saturdays.
