Statewide Monitoring (dust and smoke): The interactive map below presents the most recently available (real-time) indicative particle concentration data for the
BLANkET stations distributed around the state (including Hobart, Launceston, Devonport and George Town).
Each BLANkET station's current data can be accessed via the menu to the left, or by clicking on the points of the map below.
Reference Stations and Gas Concentrations: Use the following links see current (unvalidated) data from the main air stations of
Hobart (New Town),
Hobart Port (sulphur dioxide),
Launceston (Ti Tree Bend),
Devonport, and the partnership station at
George Town (GAMS, oxides of nitrogen and sulphur dioxide).
For background information about the network and interpreting the data see:
For information about smoke and health: visit the Department of Health and Human Services (DHHS)
smoke advice and
air alerts pages. A DHHS air advisory alert for sensitive people is enacted when the hour-average PM2.5 value is above 25 µg m-3.

Available real-time air quality data
Particle concentration data are listed on the map as "Station Abbreviation: (PM10, PM2.5)". The Station Abbreviation list is given on the map. Indicative particle concentrations are given in micrograms per cubic metre (µg m-3). Information about air quality standards is given below.
Click on a station location square on the map to obtain a current plot. Or use these in-text links to obtain a summary table of air quality at either the major stations or from the BLANkET network. Data plots are also accessible from these table pages.
Smoke will give a high PM2.5 signal. High PM10 levels without corresponding high PM2.5 levels arise from dust and/or sea-salt aerosols. Please see the important information about BLANkET data for more discussion of this. 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.
A '?' is given if data are not available for any reason or if a TEOM instrument reports a negative concentration. This can happen due to the evaporation of volatile compounds on the TEOM filter. Such events are usually of short duration. If at any station the instantaneous PM10 is over 50 µg m-3 or PM2.5 is over 25 µg m-3 the station listing will turn red. This does not signify a breach of air quality standards, but provides an indication of elevated particle levels.
Air Quality Standards
The National Environmental Protection (Ambient Air Quality) Measure (known as the Air NEPM) stipulates air quality standards in Australia. For PM10 there is a 24-hour standard of 50 µg m-3 (50 millionth of a gram per cubic metre). That is, if PM10 levels measured by a reference instrument averaged over a calendar day exceeds 50 µg m-3, an exceedance of the standard is recorded. The Air NEPM stipulates that the reporting interval is the calendar day (midnight to midnight). For PM2.5, a 24-hour (calendar day) reporting limit is set at 25 µg m-3. Currently there are no national standards for PM10 or PM2.5 for intervals shorter than 24 hours.
