EEA geospatial data catalogue
O3, European air quality data for 2025, (interpolated data), interim data, June 2026
The data set provides values for the ozone (O3) peak season combining up-to-date monitoring air quality data, chemical transport model results and other supplementary data in a ‘regression-interpolation-merging mapping’ methodology. It covers Europe for the year 2025.
The dataset for the 2025 O3 annual average concentrations using validated air quality data will be published later in 2027

The data set and corresponding maps are derived primarily from the e-reporting Air Quality database, consisting of monitoring stations data reported to EEA, and some additional EMEP (European Monitoring and Evaluation Programme) station monitoring data, supplemented with, among others, altitude, meteorological ECMWF data, EMEP concentration modelling data and satellite data. These data sets and the corresponding maps are assessment tools for use at the European scale. They may show results which differ from assessments made at national scale and should not be used to check formal compliance with regulated standards.
This data set is used to estimate population exposure to air pollution in 2025 for the EEA´s European Air quality city viewer. The methodology can be found in the 2025 ETC HE report 2025/4 "Interim air quality maps of EEA member and cooperating countries for 2024. PM, O3, and NO2 spatial estimates.", available at https://www.eionet.europa.eu/etcs/etc-he/products/etc-he-products/etc-he-reports/etc-he-report-2025-4-interim-air-quality-maps-of-eea-member-and-cooperating-countries-for-2024-pm-o3-and-no2-spatial-estimates (the corresponding 2026 report with the 2025 maps will be published at the end of 2026).
