Real-time Air Quality Data - George Town

​​In mid July 2011 a DRX dustrak and Davis meteorological station were installed at the George Town air station. These instruments are identical with those in use in the BLANkET stations. The installation was carried out by EPA Tasmania, and was funded through the GAMS committee members.

George Town Air Quality Yesterday 

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.

Final validated data from reference low-volume air samplers will be available on this website after validation. Visit our validated air quality data pages.

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

PM2.5 is an indicator of smoke, these are the red triangle symbols in the plots. PM2.5 values below 5 µg m-3 signify very clear air. On a smoky winter's evening in Hobart or Launceston PM2.5 may be near 50 µg m-3 for several hours.

National Environmental Protection Measure (NEPM) Air Standards

Particles

The 24-hour reporting standard for PM10 is 50 µg m-3. The 24-hour advisory reporting standard for PM2.5 is 25 µg m-3.
