1. EIONET Perspective – UK’s experience of air quality assessment Janet Dixon Air Quality and Industrial Pollution Programme Department for Environment, Food and Rural Affairs, UK

2. Contents Introduction Air Quality Assessment Now Future GMES Potential Opportunities Potential Obstacles Conclusions

3. Introduction Need a balance of: Observations; natural and social sciences; and research & modelling Observation platforms Ground (in situ) Balloon Aircraft Satellite Observation types Campaign Long-term monitoring

4. Air Quality Assessment - now EU, national, regional, local statutory assessments Generally consist of Monitoring (in situ; Long Term Monitoring) Modelling Emissions inventories Used for: Compliance assessment against EU Directives, UNECE protocols, national objectives, local targets Policy assessment – Pre-implementation - cost benefit and/or effectiveness analysis Post-hoc analysis

5. In situ monitoring across EEA countries Data available for calibration of satellite observations Generally high quality (fully QAQC’d to EU standards high temporal resolution (hourly over whole year) of known uncertainty (<15% or 25%) Capital 60k Euro, Running 25k Euro per yr PollutantNOxPM 10 COSO 2 O3O3 No of sites in Airbase 27702349116420742015

6. Air Quality Assessment - now Pollutants – NOx, SO 2, PM 10, O 3, CO, PAH, arsenic, cadmium, nickel, mercury, benzene (+ 26 other hydrocarbons) Information brought together by member state (including zone boundaries, populations, pollutant concentrations, exceedences of limit/target values) Reporting – compliance – manual on excel spreadsheets

7. Data flows Data available around 45 mins after end of hour Important: public information; industrial operators

8. Monitoring and Google Maps

9. Mapping Emissions and Concentrations

10. Pollutants – additional Improved assessment of uncertainties More encouragement to using modelling Reporting methodologies – more automated Information for AQ brought together from a number of sources through INSPIRE/SEIS Air Quality Assessment - future

11. Non-statutory assessments Event investigation Saharan dust; fires; industrial incidents Research Academic Campaigns Epidemiology Exposure assessments

12. Pollution event investigation

13. Particle episodes March 2007 – fires in the Ukraine Elevated PM 10 over much of UK Publicly available reports

14. Conclusions Balance of observations – type, location Opportunities Verification of emission inventories (AQ & GHG) Tracking of AQ episodes Costs – product; additional to current Availability – products, data Uncertainties – accuracy, precision Resolution – geographical (area and height)/temporal
