Historic air quality data table


Disclaimer | Siting | Planned burns

This table is for viewing historic air quality data. To see current air quality information, please go to EPA AirWatch.

To search for historic air quality data, please select ‘choose’. Then enter a date, an hour and click ‘GO’.

Disclaimer: Data on EPA AirWatch comes directly from our air monitoring stations using various types of monitoring equipment and methods. This data may be adjusted later according to set criteria to account for instrument errors, power interruptions and other technical issues.

Siting: EPA aims to locate our ambient monitoring stations so they give a good representation of the air quality experienced by the public. As most of the Victorian population lives and works close to roads, most of our stations are in population centres next to roads. This can mean we do not always comply with one of the requirements of the Australian Standard for siting (AS 3580.1.1), which specifies that air monitoring stations should be more than 50 metres away from a road. Currently, Footscray is the only EPA air monitoring site that meets this requirement.

Data for a given hour are available at 30 minutes after the following hour. For example, data for the period from 9.00 am to 10.00 am is available at 10.30 am. See the Q&A below for more information about station summaries, ‘not available’ and ‘offline’ reports.

EPA collects air quality data using a variety of different monitoring instruments, which are placed in strategic locations – these instruments make up our ‘air monitoring network’. Find out more about EPA’s air monitoring network and what we monitor.
