Numerical simulation on temporal and spatial distributions of air pollutants over the middle multi-cities of Liaoning

The distributions of SO_2,NO_2 and PM_(10) in the middle multi-cities of Liaoning were simulated by the Third-Generation Air Quality Modeling System on Jan.17～18,2002.The results showed that the change tendencies of the simulated values were consistent with those of the observed data,which indicated that the model could be used for evaluating and predicting the concentrations of SO_2,NO_2 and PM_(10) in the middle multi-cites of Liaoning.
