Analysis of distributions of hourly NO2 concentrations contributing to annual average NO2 concentrations across the European monitoring network 2000-2014

This research paper analyzes hourly nitrogen dioxide (NO2) concentration distributions across more than 2,500 monitoring sites in Europe from 2000 to 2014 to understand how different temporal and concentration-based factors contribute to annual average NO2 concentrations (NO2AA).

• Between 2010 and 2014, annual average NO2 concentrations exceeded the European Union's air quality limit value of 40µgm−3 at 8% of the more than 2,500 monitoring sites analyzed.
• Analysis of 259 sites between 2000 and 2014 shows that the contribution to annual average NO2 from winter months and rush-hour periods increased, while the contribution from peak hourly NO2 concentrations decreased.
• Sites with similar annual average NO2 concentrations can have different hourly, daily, and monthly contributions, and these patterns are not grouped by specific European regions. This suggests that NO2 reduction measures effective in one location may not be effective in another due to varying interactions between emissions, atmospheric chemistry, and meteorology.
