locations. The most severe episodes were registered in January-February 2006,
when PM
10
levels were extremely high, exceeding the EU daily limit value even
14 times. The highest daily PM
10
level equalled to 680 µg/m
3
, while hourly levels
reached up to 1,000 µg/m
3
(Juda-Rezler, 2006).
The main goal of this work is to assess the impact of climate changes on future
air quality in Poland, with emphasis to PM levels. In Europe few operational
regional chemistry transport models (CTM) are used for simulating PM. Model
evaluation studies show that most models severely underestimate the observed
PM
10
levels. In a recent PM modelling study performed for Northern Germany by
Stern et al. (2008), five European CTM's were tested for a winter-spring period of
2003 with elevated PM
10
and PM
2.5
observations. It was shown that the current
modelling systems are unable to simulate correctly higher PM
10
and PM
2.5
levels.
In this paper we are presenting results of PM simulations over Poland for
reference year 2000 of present day as well as for near future decade. We implemented
the modelling system consisting of CAMx model driven off-line by the regional
climate model RegCM3.
2. Materials and Methods
The modelling system was built at Warsaw University of Technology (WUT
modelling system) by coupling off-line Regional Climate Model RegCM3 with
chemical-transport model CAMx and emission model EMIL developed at WUT.
