Air quality API
Stream New South Wales air quality and meteorology data using an API
This air quality API enables organisations and individuals to directly stream and integrate air quality and meteorological data into subsequent applications such as mobile apps, websites, decision support tools, third-party data systems, and many other facilities.
By delivering near-real-time data via this API, the Department is supporting policy, research and business decision-makers to improve and positively influence environmental and health considerations.
What can the air quality API give you?
The air quality API provides 3 datasets, which can be accessed and streamed as current real-time hourly data, or downloaded as historical data:
- Observational data: access air quality and meteorological observational data collected from the NSW air quality monitoring network. Observational data are updated every hour.
- Station details: download monitoring station details including the site name, longitude, latitude and region name.
- Parameter descriptions: get details about the air pollutants and meteorological parameters we monitor, including averaging periods, exceedances and air quality indexes.
