Can a software predicts pollutants' path?

Researchers in Australia claim to have developed a software that can predict which way airborne odours and pollutants, from farms or factories, will actually blow.

According to them, the software package predicts local meteorology and assesses the likely pathway and concentration of pollutants as they disperse.

Lead researcher Dr Peter Hurley of CSIRO said: "The Air Pollution Model (TAPM) increases our ability to pinpoint pollutant behaviour in a wider range of atmospheric conditions.

"Over the coming years the new model will continue to fill a gap between simple air pollution dispersion models and the much more complex earth system models."

In fact, earlier versions of the software are widely used throughout Australia by researchers and consultants, as well as internationally by 190 customers in 25 countries.

From a one-dimensional model created by Dr Hurley's team in the mid-1990s, the software has now evolved into a complex environmental modelling tool with meteorological and air pollution components that will suit most local-scale environmental applications.

In Australia, the model has recently been used in Launceston where strong temperature inversions trap particulate emissions from wood fires, burning-off, vehicles and industry.

Some new research directions are also emerging, such as the use of TAPM coupled with CSIRO's complex chemistry model by CSIRO scientists Drs Martin Cope and Sunhee Lee. Applications include urban planning under future climate scenarios.
