Current GAMS Air Quality Data

​​​The George Town Air Monitoring Station (GAMS) was commissioned in July 2007 following an initiative of the then Department of Environment, Parks, Heritage and the Arts (EPA Division). The station was funded and operated in a collaborative partnership between Bell Bay Aluminium, TEMCO, AETV Power, George Town Council, West Tamar Council, and the Department of Health and Human Services with advice and support provided by EPA Tasmania.

The Station was initially equipped with instruments to measure particles as PM10 and PM2.5 using Low-Volume Air Samplers (LVAS), and later Tapered Element Oscillating Microbalance (TEOM) instruments, and the gases sulfur dioxide (SO2) and oxides of nitrogen (NOx) using gas analysers. EPA Tasmania operated and maintained the station on behalf of the partnership members. In late 2012 EPA Tasmania sequentially reduced its contribution to the station operation following resource-refocussing. In the following years the air quality instruments reached the end of their operational lifetimes.

The station now houses a DRX DustTrack instrument (optical particle counter) to measure indicative PM10 and PM2.5. Real time plots of the ​DRX data can be found on the George Town Real-time Air Quality page​.

Graphs of (historical) validated data for this station are available via the validated data portal.

The National Environment Protection Measure standards for the species measured at the GAMS are:

  • PM10 - day average: 50 ug/m3; annual average: 25 ug/m3
  • PM2.5 - day average: 25 ug/m3; annual average: 8 ug/m3
  • NOx (1 hour average) - 0.12 ppm - historical data only
  • SO2 (1 hour average) - 0.20 ppm - historical data only
  • SO2 (day average) - 0.08 ppm - historical data only

Important Note: These data are indicative only, and are provided for public information.

In keeping with legislative requirements the data are reported in Australian Eastern Standard Time (AEST) throughout the year.​​​
