Download and stream NSW air quality and meteorological data.
Our data services facility delivers air quality and meteorological data from the NSW Air Quality Monitoring Network. This large network of stations continuously measures a range of air pollutants, including ozone (O₃), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), carbon monoxide (CO), particulate matter (PM10 and PM2.5), and meteorological parameters such as temperature, wind speed and direction, humidity, and solar radiation.
The data collected is quality-assured and made freely available on this website in various formats, supporting public access, research, and decision-making related to air quality and environmental health.
There are currently 3 main facilities for accessing customised air quality and meteorology data:
| Data download facility provides an easy-to-use graphical interface to search and download historical data. |
| Application Programming Interface (API) provides the capability to stream data to a third-party application like a mobile app, in addition to searching and downloading historical data. |
 | Air quality data explorer is a map-based data search and download platform, which integrates data from the air quality API and RFS Fires-near-me. See also the SEED story for this dataset. |
Our air quality data services are accessible via our mobile-friendly website where you may view live data (Air Quality NSW), subscribe to air quality alerts (email/SMS) here, and also find the 3 above-mentioned data access facilities.
