Abstract
During the winter of 2003 there was an special particulate episode over Germany. The application of the MM5-CMAQ model (PSU/ NCAR/EPA, US) to simulate the high concentrations in PM10 and PM2.5 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 up to 75 μgm − 3 are found on average of several monitoring stations in Northern Germany. Additionally WRF/CHEM (NOAA, USA) model has been applied. In this contribution we have performed additional simulations to improve the results obtained in our contribution San José et al. (2008) [5]. We have run again both models but with changes in emission inventory and turbulence scheme for MM5-CMAQ. In the case of WRF/CHEM much 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 PM10 and PM2.5 patterns in both models. The correlation coefficient for PM10 for 80 days simulation period and for daily averages has been increased up to 0.851 and in the case of PM2.5, it has been increased up to 0.674.
