The ambient air quality monitoring station for Launceston is located at Ti Tree Bend, approximately 2.5km north-west of the city centre. Regular monitoring of airborne particles has been conducted at this site since 1992, providing valuable records showing the long-term trends in Launceston's air quality.
The station was upgraded in 2005 as part of a four year $800,000 program aimed at bringing Tasmania's ambient air quality monitoring system into line with the National Environment Protection Measure (NEPM) for Ambient Air Quality.
There is a strong seasonal cycle of air pollution in Launceston, generally with the lowest levels occur during the warmer months and highest levels during the cold months between May and August. This occurs because there are more wood smoke particles released during winter, associated with wood heaters and open fireplaces, and the atmosphere is least able to effectively disperse pollutants due to more frequent calm conditions often associated with temperature inversions. On occasions events such as bush fires can elevate levels of air pollution at any time of the year but they generally do not occur very often.
Over the last 15 years there has been a steady decrease in the number of exceedences of the National PM10 Standard for each year: from 50 exceedences in 1997 down to zero exceedences in 2009. The National goal allows for only five exceedences of the National PM10 Standard per year, which was met for the first time in 2007 with 5 recorded exceedences of the PM10 Standard.
The station includes TEOM instruments to measure PM10 and PM2.5 and a dustrack (optical particle counter) to measure indicative PM2.5. Real time plots of the dustrak data can be found
The plots below show unvalidated TEOM raw particluates data.

Today's unvalidated air quality data from the Launceston air station
The National Environment Protection Measure standards for the species measured at the Launceston Monitoring Station are:
- PM10 (day average) - 50 ug/m3
- PM2.5 (day average) - 25 ug/m3 (Advisory reporting standard)
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.
Yesterday's unvalidated air quality data from Launceston air station
The yesterday's data plot shows the real-time values measured for the whole day yesterday. 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.
