Fully integrated mesoscale meterology–photochemical air pollution modelling has been underway in Australia since 1999. The focus has principally been on PC platforms using a graphical user interface, with performance and accuracy as key objectives to compare with statistical air quality objectives. Runs involving predictions for every hour for a year are commonplace.
More recently, Australian integrated modelling has expanded in scale, to include synoptic scales, using clever mapping approaches and more complex photochemistries. The findings will be included in routine weather forecasting outputs as CSIRO works closely with Australian Bureau of Meteorology to build ACCESS.
