Comprehensive accredited air quality monitoring network
We provide the community of New South Wales with accurate and up-to-date information about air quality. Our monitoring sites are set up in Sydney and several regional areas of NSW. Download the network site information (XLSX 40KB).
Our air quality monitoring networks continuously measure particles (PM10, PM2.5), sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2) and visibility. Wind speed and direction, air temperature and humidity are also recorded. We also conduct short-term campaign monitoring activities.
Our extensive network of NATA-accredited air quality monitoring stations use Standards Australia methods where available. Technical information about the sampling methods and analytical techniques used in air monitoring programs is provided under How we monitor for air pollution.
We report the data as ambient concentrations and air quality index (AQI) values which are updated hourly and stored in a searchable database. A subset of our monitoring stations are NEPM-designated, and we report on these annually through the NSW Annual National Environment Protection Measure (NEPM) Compliance Reports. Our data undergoes a rigorous quality assurance process to ensure reliability.
