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 is 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 Servies with advice and support provided by EPA Tasmania.
The station includes a dustrack (optical particle counter) to measure indicative PM10 and PM2.5. Real time plots of the dustrak data can be found
here. The Station also has instruments to measure the gases sulfur dioxide (SO2) and oxides of nitrogen (NOx) using gas analysers.
The two series of plots below show unvalidated air quality data from the George Town air station.
The first series of plots show 10-minute averaged plots of raw particluates data (upper plot), sulfur dioxide (SO2) and oxides of nitrogen (NOx) data (central plot) and meteorological data (lower plot) from the George Town air station for the past three days.
The second series of plots show hour-averaged plots of raw particluates data (upper plot), sulfur dioxide (SO2) and oxides of nitrogen (NOx) data (central plot) and meteorological data (lower plot) from the George Town air station for the past seven days.
Graphs of annual validated data are available via the
validated data portal.
Recent unvalidated air quality data from George Town air station (10-minute data)
The National Environment Protection Measure standards for the species measured at the GAMS are:
- PM10 (day average) - 50 ug/m3
- PM2.5 (day average) - 25 ug/m3 (Advisory reporting standard)
- NOx (1 hour average) - 0.12 ppm
- SO2 (1 hour average) - 0.20 ppm
- SO2 (day average) - 0.08 ppm
Please Note: subject to network connectivity, this plot will be updated approximately every 15 minutes during the day. Use the 'Refresh' or 'Reload' button on your browser (or press F5) to refresh the plot. If networking issues do not allow real-time access on a given day, the plot will show the most recently available data.
Past seven days unvalidated air quality data from George Town air station (hour-averaged data)
The past seven days data plot shows the real-time values measured for each of the past seven days from midnight to midnight. If network issues have prevented data updates the plot will show the most recent complete day of data.
Important Note: These data are indicative only, and are provided for public information. These unvalidated data cannot be used to determine if air quality standards have been exceeded.
In keeping with legislative requirements the data are reported in Australian Eastern Standard Time (AEST) throughout the year.
