The report provides interim 2020 maps for PM10 annual average, NO2 annual average and the ozone indicator SOMO35. The maps have been produced based on non-validated Up-To-Date data reported to the AQ e-reporting database (data flow E2a), the CAMS Ensemble Forecast modelling data and other supplementary data including air quality data reported to EMEP. In addition to concentration maps, the inter-annual differences between the years 2019 and 2020 are presented (using the 2019 regular and the 2020 interim maps), as well as European exposure estimates based on the interim maps. The contribution of lockdown measures connected with the Covid-19 pandemic on the change of air pollutant concentrations during the exceptional year 2020 is briefly discussed. The decrease in road transport, aviation and international shipping intensity during the lockdown resulted in a reduction of the NOx emission, mainly in large cities and urbanized areas. Compared to 2019, a general decrease in NO2 annual average concentrations is shown for 2020, as well as a decrease in values of the ozone indicator SOMO35, apart from areas with a steep NO2 decrease. Due to the chemical processes, the decrease in NOX resulted in an ozone increase in these areas. The contribution of lockdown measures on the change of PM10 concentrations is quite complex. On the one hand, there was a decrease in emissions of suspended particles and their precursors due to decrease in transport. On the other hand, higher intensity of residential heating likely led to higher emissions of both suspended particles and their precursors.

This report presents European interim air quality maps for 2021, 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 and NO2 annual averages and ozone indicator SOMO35.

Denne rapporten presenterer databasen i ICP Materialer for perioden Oktober 2009 ¿ Desember 2009. Den inkluderer miljødata fra ICP Materialer trend-eksponeringsprogrammet for 2008 ¿ 2009. Databasen består av meteorologiske data, og forurensningsdata som gasser og i partikler. HNO3 og mengde og sammensetning av partikkelavseting ved tilsmussing rapporteres også.
