Figures used

Relative changes (%) in PM10 concentrations attributed to lockdown restrictions during April 2020 The dots represent measurements stations, where the changes have been estimated using UTD monitoring data and the generalized additive model (GAM). The background shading represents the changes estimated using CAMS chemical transport modelling with an emission inventory estimated for the lockdown conditions.
Relative changes (%) in NO2 concentrations attributed to lockdown restrictions during April 2020 The dots represent measurements stations, where the changes have been estimated using UTD monitoring data and the generalized additive model (GAM).

Average percentage change in NO2 pollution levels during the period 15th March to 30th April, due to the COVID-19 lockdown in agglomerations with more than 0.5 million inhabitants, based on satellite observations 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.

93.2 percentile of O3 maximum daily 8-hour mean in 2019 Observed concentrations of O3 in 2019.

The map shows the 93.2 percentile of the O3 maximum daily 8-hour mean, representing the 26th highest value in a complete series. It is related to the O3 target value. At sites marked with triangles in the last two colour categories, the 26th highest daily O3 concentrations were above the 120 μg/m3 threshold, implying an exceedance of the target value threshold. Please note that the legal definition of the target value considers not only 1 year but the average over 3 years. Only stations with more than 75 % of valid UTD data have been included in the map.
