Yesterday's unvalidated air quality data from Ti Tree Bend air station
The plots below show PM10 and PM2.5 indicative data (top) and meteorological data (bottom) measured yesterday at Ti Tree Bend. The day-average measurements are shown in the boxes to the right of the plots below.
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.
On the 14th of March 2012 a DRX DustTrak was installed at Ti Tree Bend. This is the same instrument as is used at the BLANkET stations. The plots show data from the DRX.
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.
Data for this station for other time intervals (including previous years) can be accessed from the Historical BLANkET Data page.
Please Note: if network connectivity has prevented remote access to the station the plot will show the most recently available complete day of data.
