The application of the MM5-CMAQ model (PSU/NCAR/EPA, US) to simulate the high concentrations in PM 10 and PM 2.5 during a winter episode (2003) in Central Europe has been performed. The selected period is January, 15 -April, 6, 2003. Values of daily mean concentrations of up to 75 µgm -3 are found on average from several monitoring stations in Northern Germany. Additionally, the WRF/CHEM (NOAA, US) model has been applied. In this contribution we have performed additional simulations to improve

We have run again both models but with changes in emission inventory and turbulence scheme for MM5-CMAQ. In the case of WRF/CHEM many more changes have been performed: Lin et al. (1983) microphysics scheme has been substituted by WSM 5-class single moment microphysics scheme (Hong et al. 2004 ); Goddard radiation scheme has been substituted by Dudhia radiation scheme and FTUV photolysis model has been substituted by J-FAST photolysis model. The results improve substantially the PM 10 and PM 2.5 patterns in both models. The correlation coefficient for PM 10 for 80 days simulation period and for daily averages has been increased up to 0.851 and in the case of PM 2.5 , it has been increased up to 0.674.
