EPA Tasmania, air-quality news.
This page will provide updates and notifications of air-quality-related issues in Tasmania.
Some of the information here should be regarded as preliminary, and will be subject to later updates.
New entries will be added, in date order, above earlier entries.
- 20 December 2017 : Smoke in northern Tasmania, 16-17 December 2017:The moderate smoke around the north coast of the state on the 17th of December 2017 appears to have originated in the bushfire to the south of St Helens. St Helens station recorded high levels of smoke at times on the 16th and 17th of December: Near 4 a.m. (AEST) on the 17th of December a southerly wind moved smoke north to St Helens, then a wind shift to an easterly wind moved smoke to the west, over the north-east, Tamar and some of the north-west coast. This can be seen in this visualisation of the station PM2.5 and wind data for the north of Tasmania for the 17th-18th of December.
- 20 December 2017 : Data visualisations: For several years we have been making 'visualisations' of the network data to aid in our analysis. These are videos showing a map of Tasmania with the instantaneous PM2.5 at each station represented by the size and colour of a symbol, with the wind speed and direction shown as an arrow. Each frame of the video shows a different time-snapshot. We've not published these previously as they often were of large size, and some browsers would not play the specific video format. We have been experiementing making some (lower image quality) animated GIFs of these videos, and we are now making some available. At this link you can find a visualisation of the station PM2.5 and wind data for Tasmania for the 4th to 8th of April 2017. Description: Late on the 4th and into the early hours of the 5th of April there is smoke in the south of the state from various planned burns in the general area. There is more smoke in the south late on the 5th and again into the 6th of April. Smoke appears in the north of the state around the middle of the 6th and into the 7th (when concentrations are high) and extending into the 8th of April. The smoke in the north largely arrives on a northerly air flow. Analysis (to be presented shortly) identifies the source of the smoke that impacted in the north as chiefly being from planned burns (over several days) in Victoria.
- 15 December 2017: Reports available: Papers presented at the biennial meetings of the Clean Air Society of Australia and New Zealand (CASANZ) by EPA Tasmania Air Section officers are available from the BLANkET reports page. There may be minor differences between the versions here and the final papers available from CASANZ.
- 14 December 2017: Woodheater smoke: A new section of our Air web pages on woodheater smoke is now published.
This includes links to our car-based smoke measurement survey data (via The LISTmap) and woodheater use in Tasmania.
More information and links are likely to be added in future.
