  2. Introduction Emission inventories files required by Models-3/CMAQ for applications in the United States are processed by tools such as MEPPS or SMOKE, integrating national or regional emission databases with results by emission models (e.g. MOBILE6, BEIS3) Application and exploitation of Models-3/CMAQ in other regions is conditioned to the applicability and potential adaptation of these emission tools We developed the EMICAT2000 emission model for its implementation within Models-3/CMAQ applications in the northeastern Iberian Peninsula (Catalonia, Spain).Air pollutants emissions are related with ozone (O3) pollution episodes. EMICAT2000 is a GIS emission model developed with high spatial (1 km2) and time (1 h) resolutions

  3. EMICAT2000 (Emissions from Catalonia for year 2000) Prioritized sources Primary pollutants NOx, VOC, CO SO2, TSP Greenhouse gases: CO2, CH4, N2O • Vegetation • On-road traffic • Industries

  4. Vegetation The emission model from vegetation (isoprene, monoterpenes and other NMVOCs) describes the particular emitter behaviour of some Mediterranean species. Emission factors by land-use categories were defined, as result of an exhaustive selection of emission factors of the most important vegetal species. A huge database of hourly records of superficial temperature and solar radiation was incorporated. Isoprene emission model (Guenther et al. 1993) iso = = .DBF FE . CT .CP .Area E (k, t) E (k, hourly) j j iso iso k

  5. Vegetation NMVOCs emissions (15 August, 2000) Isoprene OVOC Monoterpenes

  6. On-road traffic Emission model includes the hot exhaust, cold exhaust and evaporative emissions, using a digital map of the all the highways and the most important roads and streets (daily average traffic > 3000). EMICAT2000 uses the method and emission factors of the European model EMEP/CORINAIR – COPERTIII, and includes monthly, daily and hourly traffic profiles; differencing the vehicle park composition between weekdays and weekends. Hot exhaust emissions model:

  8. Hourly NOx emissions due to on-road traffic Weekday Weekend

  9. Emissions of industrial stucks are connected to the Web of Emissions Controls of the Environmental Department of the Catalonia Government. Industrial Emissions Power plants Co-generation Incinerators Cement plants Refineries Chemical Industries Other plants

  10. Summary of emission by sources in Catalonia during year 2000

  11. Comparison of annual emissions Different spatial resolution: EMEP vs. EMICAT2000 EMEP EMICAT2000

  12. Monthly emissions of NOx and NMVOC

  13. Contribution of speciated NMVOCs (14 August 2000)

  14. Hourly ALD2 emissions (14 August 2000)

  15. PAR (paraffin bond) emissions with different spatial resolution (12 LST, 15 August 2000) Cells of 1 km by side

  16. PAR (paraffin bond) emissions with different spatial resolution (12 LST, 15 August 2000) Cells of2 km by side

  17. PAR (paraffin bond) emissions with different spatial resolution (12 LST, 15 August 2000) Cells of4 km by side

  18. PAR (paraffin bond) emissions with different spatial resolution (12 LST, 15 August 2000) Cells of8 km by side

  20. EMICAT2000 – MM5 – MODELS-3/CMAQ FRAMEWORK Meteorological model Emission model Chemical transport model

  21. Integration of emissions files into Models-3/CMAQ • Text emission files are built in two sections: • the header, containing information about the configuration of the study domain • 2) the emission data organized according to the netCDF protocol. Figure shows the arrangement of rows and columns on the XY plane. Indexes follow the relations: i+1 = ROW, j+1 = COL, k+1 = LAY; being ROW, COL, and LAY the number of rows, columns and layers, defining domain

  22. Conclusions We developed the EMICAT2000 model, which estimates emissions for the complex configuration of Catalonia (northeastern Iberian Peninsula). This model provides directly the emission files required by Models-3/CMAQ Successful results of O3 modelling are currently obtained (Jiménez et al., 2004) This approach could be considered for similar exploitation of Models-3/CMAQ in different regions worldwide
