Annual mean NO2 concentrations

info:
The annual mean NO2 concentrations are published in the table below. The annual mean is the average of all hourly mean concentrations in a calendar year (1/1 till 31/12).
According to EC directive 1999/30/EC the annual limit value of 40 μg/m3 may not be exceeded from 01/01/2010.
The measuring stations are put in decreasing order by the running annual mean(info) during the present year. The data from the previous years are posted as additional information.

(info) : Running average : average of the daily mean concentrations from 27/05/2021 till 27/05/2022. This period shifts daily with one day. A compliancy check with the EU limit value will only be possible on 31/12.

"NA" means that there were less then 75% available days with sufficient measuring data to calculate the annual mean PM10 concentration..

(*) Calculated with not validated data

(**) Between 1 August and 21 November 2018, a technical problem occurred at the Ixelles monitoring station (41R002) resulting in an underestimation of nitrogen dioxide concentrations. Data measured during this period have been invalidated. As a result, the minimum data acquisition rate required by Directive 2008/50/EC (90%) is not respected at this station and the annual average of 42 μg/m3 is not representative. However, this station would probably exceed the European annual limit value of 40 μg/m3 if the 90% data acquisition rate was respected.

The siting criteria for this monitoring station are not in accordance with the prescriptions in EU directive 2008/50/EG (Annex III).
