27. 1 st Chimere workshop 21-22 March 2005Stortini,Bonafe,Deserti,Minguzzi,Jongen Suburban station (2) NINFA4 seems fairly reproduce NO 2 concentrations over the major part of stations

28. 1 st Chimere workshop 21-22 March 2005Stortini,Bonafe,Deserti,Minguzzi,Jongen Discussion and conclusions  NINFA has been implemented at ARPA-SIM. This model provides simulation results for PM and gas species.  Compared to continental model NINFA improve substantially NO 2 simulation probably due to more accuracy of anthropogenic emission; comparisons with available data at background and suburban stations give acceptable results on PM10 only in few stations although NINFA gives better results. Some open questions:  The introduction of Point source emission scheme could improve substantially model skill especially over Po Valley?  Secondary organic matter vs. resuspension

29. 1 st Chimere workshop 21-22 March 2005Stortini,Bonafe,Deserti,Minguzzi,Jongen Further works  Implementation of latest version of Chimere  Test with increasing the model secondary organic matter and/or resuspension  Long-term simulations (summer and winter seasons)
