EPA AirWatch data shows air quality information measured by EPA’s air monitoring stations around Victoria. Data at each location is updated each hour. This extract is an annual report of 1-hourly Average air quality measures per paramater across all stations for the year.
Air monitoring information is also available in the Historic air quality data table.
On occasion, data may not show for a variety of reasons, such as monitoring station maintenance, equipment breakdown or website issues.
During winter months, EPA switches off equipment that we use to monitor summer ozone in parts of our network (mostly in metropolitan Melbourne). We will switch them back on before the start of next summer.
Please see the 'Data info Panel' Tab for full dataset meta-data.
