# NO2, European air quality data for 2022, (interpolated data), June 2024

The data set provides values for the human health related indicator of NO2 (annual average concentration) at 1 km2 grid combining monitoring air quality data in a ‘regression-interpolation-merging mapping’ methodology and the observational values of the air quality monitoring stations used in the interpolation. It covers Europe for the year 2022.

This data set is used to estimate population exposure to air pollution, and for the health impact assessments published by the EEA (see, for example, Harm to human health from air pollution in Europe: burden of disease 2023 at https://www.eea.europa.eu/publications/harm-to-human-health-from-air-pollution/harm-to-human-health-from). The methodology can be found in the 2023 ETC HE report 2023/3 "Air quality maps of EEA member and cooperating countries for 2021. PM10, PM2.5, O3, NO2, NOx and BaP spatial estimates and their uncertainties" https://www.eionet.europa.eu/etcs/etc-he/products/etc-he-products/etc-he-reports/etc-he-report-2023-3-air-quality-maps-of-eea-member-and-cooperating-countries-for-2021-pm10-pm2-5-o3-no2-nox-and-bap-spatial-estimates-and-their-uncertainties (the corresponding 2024 report with the 2022 maps will be published at the end of 2024).https://sdi.eea.europa.eu/geonetwork/srv/api/records/9f624659-d559-4935-9a84-9a01f98fdc2d
