Interim changes to our air network, mainly in metropolitan Melbourne, started on 27 February 2015.
A number of instruments across the network will go offline for a short time, which will be noticeable on EPA’s website. The instruments coming offline are used to monitor seasonal pollution issues such as ozone, which is mainly detected over summer.
Across the network, we will continue to monitor for smoke from bushfires.
EPA measures a range of pollutants at each of its monitoring stations and provides air quality bulletins that aim to display air quality data in a meaningful form. This section describes the bulletins and how the information in them is calculated.
