# NO2, European air quality data for 2019 (interpolated data), Mar. 2022

The data set provides concentrations for the air pollutant NO2 at 1 km 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 2019. It provides estimates for human health related indicators of pollutants NO2 (annual average).

This data set is used to estimate population exposure to air pollution, and for the health impact assessments published in the Air Quality in Europe reports (https://www.eea.europa.eu/publications#c7=en&c11=5&c14=air-quality-reports&c12=&b_start=0). The methodology and the corresponding maps can be found in the 2021 Eionet report "European air quality maps for 2019. PM10, PM2.5, Ozone, NO2 and NOx Spatial estimates and their uncertainties" (ETC/ATNI Report 1/2021) available at
