21Emission inventories
- EMEP emission inventory 50 x 50 km
- Detailed city inventories
- Berlin 2 x 2 km, variable in vertical
- Prague 5 x 5 km, no vertical variation,
- Katowice 5 x 5 km, variable in verticalonly
small part of the CityDelta domain
22Emission inventories - problems
- Different treatment of emission sources
- Different maximum values in urban area
- Different resolution
- Overestimated EMEP emissions
- Final emission field not consistent
23Emission field (NO - ground level)
24Preliminary results
- 1 - 15 of April 1999
- O3 (ppb) - bottom layer (20 m)
- NO and NO2 (ppb) - bottom layer (20 m)
- Meteorological parameters (temperature, pressure,
wind speed and direction) - Hourly values

35Issues
- Large domain ? impact of synoptic scale
meteorology and long range transport of
precursors - Urban heat island parameterisation
- 2 - 5 km ? resolved scale
- different dynamical and chemical processes
- Consistent emission inventories
- Model performance during episodes - how much
episodes influence AOT40 values ?
36Conclusions
- Planned improvements for MC2-AQ
- Test run performed with IC/BC from GEM-AQ(EMEP
values too low) - Additional cascade run (10 km resolution)- IC/BC
improvement for 3 km resolution run - UHI parameterisation in MC2-AQ (Martilli, 2001)
- evaluation of vertical mixing and deposition
parameterisation(ESCOMPTE Modelling Exercise)
