High-Resolution Environmental Modelling for Croatia: EMEP4HR Programme

The EMEP4HR team developed high-resolution emission inventories and a unique Eulerian chemical transport model for urban air quality assessment in Croatia. The project aimed to meet EU air quality legislation and analyze different emission scenarios.

  1. High Resolution Environmental Modelling and Evaluation Programme for Croatia

  2. The EMEP4HR team (8+10) • MET.NO: Anna Carlin Benedictow, Hilde Fagerli, Agnes Nyiri, David Simpson (coordinator 2009-2010), Per Helmer Skaali, Leonor Tarrason (coordinator 2006-2009), Semeena Valiyaveetil and Peter Wind • MHSC: Sonja Vidič, Amela Jeričević, Lukša Kraljević, Domagoj Mihajlović, Kornelija Špoler Čanić • AMGI: Branko Grisogono, Zvjezdana Bencetić Klaić, Danijel Belušić • EKONERG: Davor Vešligaj, Duška Šaša

  3. Aims of the project (2006-2009) To develop high resolution emission inventories of air pollutants in Croatia and in selected two urban areas To implement and further develop a high-resolution unique version of the Eulerian chemical transport model for use in Croatia To develop a new capability for the assessment of urban air quality in main Croatian cities To support Croatian authorities to meet the requirements from the new EU legislation on air quality

  4. GOALS • To make model based assessments of air quality at national and at urban levels, • To evaluate national consequences of proposed international environmental control options, and • To analyse effects of different emission scenarios

  5. Dimension of a problem NOx Emissions, EMEP NMVOC Emissions, EMEP

  6. Emissions in 10 km x 10 km Emissions in 50 km x 50 km

  7. Emissions in 10 km x 10 km Emissions in 50 km x 50 km

  8. Individual emission sources Air Quality Management Areas

  9. Modelling domains

  10. Modelling and study domain

  11. IMPLEMENTATION DEVELOPMENT OF THE ACTION PLAN FOR REDUCTION OF SURFACE OZONE IN AIR QUALITY MANAGEMENT AREAS (RURAL AND POPULATED) STUDY OF OZONE

  12. EMEP4HR MODEL IS USED TO • Assess the spatial distribution of ozone and NO2 conc. • Calculate the exceedences • Calculate health related SOMO35 values • Calculate AOT40 cummulative values for forests and crops • Compare measured and modelled concentrations Calculations were made for 4 different emission scenarios: • Full modell run – all emission • Model run excluding all Croatian emissions • Model run with the scenario of 30% NOx reduction from all Croatian emission sources and SNAP sectors • Model run with the scenario of 30% NOx reduction from emission sources in energy and industrial sectors (SNAP1 and SNAP3 sectors)

  13. Ozone monitoring sites in 2006 Iskrba

  14. Ozone monitoring sites 2010, rural

  15. SELECTED RESULTS Mean monthly values

  16. 8-hr max value – full run (S0) run without HR emissions (S1)

  17. Ozone daily mean value, full run S1 run, % difference

  18. AOT40 forests AOT40 crops

  19. SOMO35 health indicator Run S1 Run S2 30% Run S3 30% Run S0

  20. Number of days with the excedences

  21. Ozone NO2

  22. NO2 average daily concentration fields Full run S1 run – no HR emissions

  23. S0 NO2 average daily concenrations for all 4 runs S3 S2 S1

  24. Implications NOx and VOC Reduction Limitation Regimes NO2 reduction increase in O3

  25. Comparison of monthly measuredand modelled values

  26. Measured vs. Modelled Average Daily Ozone Concentrations Iskrba
