Further Development of the UK Application of the EMEP model EMEP4UK 2011-2014 - AQ0727

The proposed work plans to further develop and test the EMEP4UK model to make it operational over annual timescales. The model will be developed to support of policy on abatement of pollutant emissions affecting environmental emissions such as sulphur and nitrogen deposition, surface ozone and particulate concentrations. The aims of the project are:
• To provide an advanced modelling tool that can support UK transboundary air pollution policy evaluation, incorporating the effects of actual meteorology and allowing the analysis of future scenarios for different years.
• To provide a platform for ongoing exchange of knowledge between the UK and the EMEP programme, facilitating improved understanding of the EMEP model as used in calculations for the CLRTAP.
• To provide a vehicle by which the effects of new UK scientific findings can be considered within a sub-domain of the EMEP model, with consideration for eventual application in the full EMEP model used in the CLRTAP
1: Extension of the number of meteorological years available for policy applications

Task1: Evaluation of how the UK atmospheric composition is affected by shipping especially for ozone and nitrogen compounds and identification of sites locations best located to monitoring this effect and participation in Defra’s modelling inter-comparison exercise (MIE).

Task 2: Calculating 10+ years of UK meteorology using the WRF model and UK chemical composition using the EMEP4UK model staring from 2001.

Task 3: Extending the verification of WRF and EMEP4UK results against the UK monitoring network for the additional meteorological years simulated.

2: Policy relevant application of the EMEP4UK model for scenario analyses

Task 4: Ad-hoc scenarios in response to Defra requirement and analysis of best cost-effective SR application of the EMEP4UK model for the UK.

Task 5: Extending the available meteorology to the latest 2011 and updating the emissions using the latest NAEI emissions estimate available. EMEP4UK data will be published on the Defra and CEH web sites.

Task 6: Uncertainty/Sensitivity analysis of the EMEP4UK model framework.

Task 7: Extending the meteorology to the latest 2012 and updating the emissions using the latest NAEI emissions estimate available. Updated EMEP4UK data published on Defra and CEH web site.

3: Emerging science and further model development

Task 8: Extending the EMEP4UK model to secondary organic aerosols and exploring other chemical schemes (i.e CRI). This will include inter-comparison and knowledge exchange with other UK and international research groups which use different model such as WRF-CHEM, CMAQ and UKCA.

Task 9: UK air quality Sensitivity to long-range transport of secondary pollutant including secondary inorganic aerosols and secondary organic aerosols.

Task 10: Examination of multi-pollutant and co-benefit approach to investigate emissions reduction scenarios, changes in agricultural practice and human behaviour, which together may give a larger improvement in air quality and ecosystem recovery than each implementation alone.

Task 11: Summary of science learned and its importance and relevance for policy application.

Additional optional task (and the associated additional cost):
Task A (included): Exploring the coupling of the EMEP4UK with the Atmospheric Dispersion Modelling System (ADMS) of Cambridge Environmental Research Consultants (additional cost of £ 5,000 for 5 days staff effort of a member of the ADMS team). (The additional work for CEH is anticipated to be 2-3 days and as such would be rolled into other tasks if this option is taken up).

Task B: Developing an EMEP4UK interface and more generally extending Open-air to easily ingest the standard NetCDF output from any numerical weather prediction model and atmospheric chemistry transport models. Further statistical analysis of the EMEP4UK model will be explored here in collaboration with David Carslaw (KCL) to better quantify the model performances versus observations and other models. This task will have an additional cost of £ 7,000 which covers the expenses for 4-5 meetings in London and/or Edinburgh.

TASK C: Knowledge exchange between the UK and US CMAQ community and the EMEP4UK team. A series of workshops are usually held throughout the year in the UK and/or the US for the CMAQ user community. The EMEP4UK will benefit from a direct interaction with CMAQ users. The cost is not included in the proposal. An additional £ 7,000 is anticipated to allow a member of the EMEP4UK team to present and discuss the result in CMAQ workshops/conferences thought the project.
