Special projects monitoring

View the latest air quality index (AQI) and concentration values for data collected from special monitoring projects.


The Katoomba Air Quality Monitoring Station is part of the Blue Mountains and Lithgow Air Watch Project led by NSW Environment Protection Authority (EPA). Blue Mountains and Lithgow Air Watch is a temporary (12-month) project initiated by the local community to measure ambient air quality in the Blue Mountains and Lithgow. The project started in May 2019 and will conclude in May 2020. 

As part of this project, 12 low-cost air quality (KOALA) sensors developed by Queensland University of Technology have been deployed at locations selected by community representatives. The use of KOALA sensors provides a cost effective and easy-to-operate way of observing air pollution trends across the Blue Mountains and Lithgow areas. 

KOALA sensors used in this project do not comply with Australian Standards and only provide indicative measurements of PM10, PM2.5 and carbon monoxide. Current data from the KOALA sensors can be found on the KOALA webpage. Note that this website works best on the Chrome browser. 

Further information regarding the Blue Mountains and Lithgow Air Watch Project can be found on the EPA's webpage.

Disclaimer: The data used in the compilation of this page have undergone only preliminary quality assurance checks. These data may require modification during final stages of validation as a result of calibration changes, power failures, instrument failures etc.
