A land-use regression model (based on 5220 NO2 monitors in 58 countries and land use variables) estimates nitrogen dioxide concentrations for 2010-12. NO2 column densities from the Ozone Monitoring Instrument and MERRA-2 scale the concentrations to other years between 1990 and 2020.

DataSetQuality:
The model captures 54% of global NO2 variation with a mean absolute error of 3.7 ppb. Model performance is higher in South America (R2=0.67) and North America, Europe, and Asia (R2=0.52) than in Africa (R2=0.42). Anenberg, Mohegh, et al. (2022 Lancet Planetary Health) compare the dataset in 2019 to observed concentrations from 4348 monitors in the United States, Canada, and Europe in both urban and rurals areas.
