Regional-to-local scale air quality modelling for Ireland
The project will couple regional and local scale models using CERC's ADMS-Urban Regional Model Link. This will combine regional modelling undertaken by the UK Centre for Ecology and Hydrology using the Weather Research and Forecasting (WRF) mesoscale meteorological model and the EMEP regional chemical transport model, with local modelling carried out using CERC's street-scale resolution air quality modelling tool, ADMS-Urban.
The modelling will use gridded MapEIRE emission data, compiled by the Department of Environmental Science at Aarhus University in Denmark, as input to both the local and regional scale modelling. CERC will also develop a local-scale emissions inventory for the five main cities in Ireland (Dublin, Cork, Limerick, Waterford and Galway) and Ireland's major road network using EMIT.
This project builds on the success of CERC's previous Dublin air quality modelling work for the EPA, which was widely reported by local and national media. CERC will also provide training in air pollution mitigation strategy assessment for the EPA air quality team, allowing them to take the work forward.
The figure shows 2017 annual average NO2 concentrations modelled using ADMS-Urban as part of the earlier study.
