# PM2.5, European air quality data for 2024, (interpolated data), interim data, June 2025

The data set provides values for the human health related indicator of PM2.5 (annual average concentration) at 1 km2 grid 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.

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).

The dataset for the 2025 PM2.5 annual average concentrations using validated air quality data will be published later in 2027https://sdi.eea.europa.eu/catalogue/srv/api/records/72a465a6-4af1-4b0c-ade5-ddfa23cc19fe?language=all
