12 Jul 2019Irish EPA assesses NO2 in Dublin using ADMS-Urban

The Irish Environmental Protection Agency has published new evidence on NO2 levels in Dublin. The report has been widely covered including by The Irish Times and RTE.

The EPA report draws on a modelling study carried out by CERC using ADMS-Urban. CERC used traffic data provided by Dublin City Council, and emissions data from the EPA and the MapElre project. LIDAR height data was analysed to derive building parameters for the ADMS-Urban advanced street canyon module. Modelled concentrations were compared with measurements from continuous monitors and a diffusion tube study; overall, the model performed well.

The report identifies areas likely to breach the EU 40μg/m3 limit value for annual average NO2 concentrations: several streets in the city centre, the M50 motorway and the area around the entrances to the Dublin Port Tunnel.

The EPA is using both of the studies to help expand the national monitoring network as part of the National Ambient Air Quality Monitoring Programme 2017-2022. If further monitoring confirms exceedences of the EU limit value, the local authorities will be required to produce an Air Quality Action Plan.
