摘要: A Circuit Trajectory transfer-coefficient model (CTx) is developed in this study based on the parameterization presented in a companion paper (Tsuang et al., Atmos. Environ., in this issue). CTx was tested by applying it to Metropolitan Taipei for the entire year 1998. The model was calibrated in January and verified throughout the year. The results indicate that the correlation coefficients (r) for daily concentrations of CO, NOx, SO2, PM2.5, and PM10 were 0.75, 0.69, 0.39, 0.55 and 0.55, respectively, with biases of the means ranging from 0% to 20% during the verification period. According to contour plots of contributed concentrations to the city, "teleconnections" between source emissions and their contributions to the city can be identified. In addition, the model captures most of the dust episodes except during the periods of Asian dust storms. The sensitivity analysis shows that the calculated PM10 concentration is most sensitive to its dry deposition velocity as well as its emission rate. A more thorough study on the deposition velocity of PM2.5 is suggested. (C) 2002 Elsevier Science Ltd. All rights reserved.
