The map shows the average percentage change in NO2 pollution levels from NO2 TROPOMI satellite observations during the period 15th March to 30th April, comparing the observations under the COVID-19 lockdown to the business-as-usual scenario, in European agglomerations with more than half a million inhabitants. The gradient boosting regressor machine learning technique was used to simulate a business as usual (BAU) NO2 tropospheric columns satellite observations.
