Elevated levels of NO2 are of concern to our urban communities as it affects human health. Particulate matter 10 μm or less in diameter (PM10) is also known to have adverse effects on human health and the environment.
This dataset presents a spatial distribution of the modelled annual average NO2 and PM10 concentrations in the year 2008, highlighting pollution hotspots in the Greater Sydney area.
Modelled concentrations were generated by adapting ERG's London Air Qualit...

- Data Quality
- The NO2 and PM10 concentrations are plotted on a 1km x 1km point 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 for presentation as grids, and the point sources' emissions then also added to the model on this grid. The grids were then resampled back to 1km x 1km cell size and converted to point format for presentation in systems that require vector data.
- Supplemental Information
The modelled concentrations were produced using 2008 emissions provided by the Office of Environment & Heritage, NSW.
