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 New South Wales. Download the network site information (XLSX 65KB).
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 uses 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 category ratings, which are updated hourly and stored in a searchable database. A subset of our monitoring stations is NEPM-designated and we report on these annually through the NSW National Environment Protection Measure (NEPM) annual compliance reports. Our data undergoes a rigorous quality assurance process to ensure reliability.
