Elevated levels of NO2 are of concern to our urban communities as it affects human health. This resource presents a spatial distribution plot of the modelled annual average NO2 concentration in the Greater Sydney area in the year 2008.
Modelled concentrations were generated by adapting ERG's London Air Quality Toolkit (LAQT) for Sydney, using local meteorology and emissions data. The model is a simplified version, owing to the limitations in spatial resolution of available em...

- Data Quality
- The NO2 concentrations are plotted on a 20m x 20m grid and expressed in µg/m3. The modelled data were validated against reference monitors operational in 2008 in the Greater Sydney area. Other than for industrial point sources, the emissions were only available at km2 resolution. Therefore the model was only run at km2 level, before being interpolated to a 20m x 20m, and the point sources' emissions then also added to the model on this grid.
- Supplemental Information
The modelled concentrations were produced using 2008 emissions provided by the Office of Environment & Heritage, NSW.
