# O3, European air quality data for 2024, (interpolated data), interim data, June 2025

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 2024.

The dataset for the 2024 O3 peak season concentrations using validated air quality data will be published later in 2026, together with the maps for the rest of O3 indicators.https://sdi.eea.europa.eu/catalogue/srv/api/records/839407de-bb7c-4cc4-91b9-a8282b05203a?language=all
