ETC HE Report 2023/4: Interim air quality maps of EEA member and cooperating countries for 2022. PM10, O3, and NO2 spatial estimates and evaluation of PM2.5 interim mapping.

This report presents European interim air quality maps for 2022, which are based on the non-validated up-to-date (UTD) measurement data and the CAMS Ensemble Forecast modelling results, together with other supplementary data. It contains maps of PM10 annual average, ozone indicator SOMO35 and NO2 annual average. Next to this, the report evaluates the PM2.5 annual mean interim mapping.

The report presents interim 2022 maps for PM10 annual average, O3 indicator SOMO35 and NO2 annual average. The maps have been produced based on the 2022 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 2017-2021 and 2022 are presented (using the 2017-2021 regular and the 2022 interim maps), as well as basic exposure estimates based on the interim maps. The report also evaluates the PM2.5 interim mapping, based on 2021 data. The PM2.5 interim map for 2021 has been prepared based on the non-validated E2a (i.e. UTD) data and evaluated based on the validated E1a data. Following this, the PM2.5 interim map for 2022 has been also constructed based on the E2a 2022 data.
