Verification of a prognostic meteorological and air pollution model for year-long predictions in the Kwinana industrial region of Western Australia

摘要: Abstract A prognostic air pollution model (TAPM) has been used to predict meteorology and sulphur dioxide concentration in the Kwinana industrial region of Western Australia for 1997, with a view verifying TAPM use environmental impact assessments associated studies. The regulatory plume model, DISPMOD, developed also run using both an observationally based meteorological file (denoted DISPMOD-O) TAPM-based DISPMOD-T). predictions 1997 compare well observed values at each five monitoring sites. Root mean square error index agreement temperature winds indicate that performs predicting meteorology, compared performance similar models from other yearly average, 99.9 percentile, maximum top 10 ground-level concentrations were predicted by all runs, although DISPMOD-O DISPMOD-T tended overpredict extreme statistics sites furthest sources. Overall, performed better than DISPMOD-O, which turn DISPMOD-T, considered, but we consider three sets results are sufficiently accurate applications. ten is generally considered be robust statistic applications, show site-averaged value 95 μg m−3, 94 μg m−3, 111 μg m−3 125 μg m−3. approach modelling TAPM, gives comparable or current (DISPMOD), indicates currently accepted prognostically determined will acceptable regions without observations. There nothing was specifically region, so feel could applied equally regions, performance. disadvantage approximately 1000 times longer CPU time required such as anticipate two approaches complement applications near future.
