A new LiDAR (Light Detecting and Ranging) study at Mandogalup

The previous Point Samson and Port Hedland LiDAR studies were published on the department’s website and demonstrated the valuable contribution of the technology in determining dust sources and pathways. The LiDAR technology completes a circular scan every few minutes, over a distance of up to six kilometres, and generates a map of particles in the air at the time.

A 12-month field trial of a vehicle-mounted Remote Air Pollution Infrared Detector (RAPID) completed in October 2017

This technology was subsequently deployed throughout the metropolitan region in several investigations of emissions. The RAPID is able to detect 87 air toxics, through the use of an infrared detector that can automatically monitor and identify industrial chemicals – from a distance of up to five kilometres away – providing reliable identification of gas plumes. The technology has proved invaluable in detecting emissions from industrial facilities from a distance in real-time, allowing department staff to immediately investigate the issue and sources of pollution.
