Performance Evaluation and Sensitivity Analysis of the General Finite Line Source Model for CO Concentrations Adjacent to Motorways: A Note
The relative performance of two atmospheric dispersion models, the general finite line source model (GFLSM) and CALINE4, is assessed using carbon monoxide levels measured adjacent to a four lane motorway. The CALINE4 model has already been validated for Irish motorway conditions and the performance of the GFLSM is looked at under similar conditions. The performance of the model is tested using composite and hourly emission factors calculated with the COPERT III methodology. The model performed best for neutral stability conditions and wind speeds greater than 0.5 m/s. The modelled and predicted data were fitted to statistical distributions and it was found that the modelled and predicted data follow the Weibull distribution.
