# NOx, European air quality data for 2018, (interpolated data), Jan. 2021

The data set provides concentrations for the air pollutant NOx 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 2018. It provides estimates for the vegetation related indicator of pollutant NOx (annual average) for the year 2018.

This data set is used to estimate vegetation exposure to air pollution. The methodology and the corresponding maps can be found in the 2020 Eionet report "European air quality maps for 2018. PM10, PM2.5, Ozone, NO2 and NOx Spatial estimates and their uncertainties" (ETC/ATNI Report 10/20) available at https://www.eionet.europa.eu/etcs/etc-atni/products/etc-atni-reports/etc-atni-report-10-2020-european-air-quality-maps-for-2018-pm10-pm2-5-ozone-no2-and-nox-spatial-estimates-and-their-uncertainties-1.https://sdi.eea.europa.eu/geonetwork/srv/api/records/c513e897-3ea2-42f9-b61e-cc9be8a70a86
