ETC HE Report 2025/4: Interim air quality maps of EEA member and cooperating countries for 2024. PM, O3 and NO2 spatial estimates

The report presents interim 2024 maps for PM10 annual average, PM2.5 annual average, O3 indicator peak season average of maximum daily 8-hour means, and NO2 annual average. The maps have been produced based on the 2024 non-validated E2a (UTD) data of the AQ e-reporting database, the CAMS Ensemble Forecast modelling data and other supplementary data. Together with the concentration maps, the inter-annual differences between 5-year average 2019-2023 and 2024 are presented (using the 2019-2023 regular and the 2024 interim maps), as well as basic exposure estimates based on the interim maps.
