Modelling SIG


Air quality modelling continues to be one of the primary tools available for assessing air quality impacts. Indeed, dispersion modelling is becoming more and more a part of licensing emissions to the atmosphere throughout Australia, and there is growing awareness of the role that air quality modelling can play in areas such as air resource management, risk assessment and land-use plannings.


The primary purpose of ModSIG is to bring together CASANZ members who have an interest in the development and/or application of air quality models in order to exchange ideas, identify common problems, inform members of new developments, and establish, as appropriate, a 'ModSIG view' on issues of relevance.
