Real-time Air Quality Data - Rowella


NOTE: Rowella station was closed on the 20th of September 2012.  These pages are provided for historical information, but may be removed at a future date.


The two plots below show today's and yesterday's unvalidated air quality data from the Rowella air station (Lower Tamar Valley).

Please see the information about BLANkET and interpreting the data plots.

Today's unvalidated air quality data from Rowella air station

Rowella Air Quality Today

Please Note: subject to network connectivity, this plot will be updated approximately every 60 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 Rowella air station

Rowella 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. The Rowella PM10 and PM2.5 data are obtained with Tapered Element Oscillating Microbalance (TEOM) instruments. The PM2.5 TEOM is relatively new technology for Tasmania, and its performance under Tasmanian conditions is being evaluated.

Final validated data from reference low-volume air samplers will be available on the EPA Division's 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 square 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.

SO2 and NOx:

The hourly standard for SO2 is 200 ppb (parts per billion), and the daily (24-hour) standard is 80 ppb. The hourly standard for NOx (measured as NO2) is 120 ppb.

Rowella Webcam

The image is automatically updated approximately every 30 minutes. This is a trial of the technology. At certain times the camera will be static for long intervals, at other times the viewing direction may change several times during a day.
