Smoke Observation Network

As part of this activity, we enhance near real-time smoke observation capabilities to support model validation and contribute to regional data assimilation and bias reduction. 

We use a range of observational data sources, including:

• Data feeds from state environment agencies’ air quality monitoring networks
• Data from a low-cost particle sensor network
• Satellite-based observations

We aim to deploy over 100 low-cost particle sensors (SMOGs or Purple Air sensors) into data-sparse, smoke-affected regions across Australia. This significantly boosts the national smoke observation infrastructure.

The SMoke Observation Gadget (SMOG) unit was originally developed by CSIRO and local engineering firm 4Volts in 2017 as part of a STEM initiative (https://ecos.csiro.au/smog/). Since then, further developments and improvements have been applied to the original SMOG units in partnership with 4Volts. 

In addition to expanding ground-based monitoring, we are also optimizing satellite-sensor algorithms to improve smoke detection accuracy across the Australian region.

These enhancements greatly improve the ability of decision-makers to conduct real-time analysis of smoke extent and exposure, supporting more informed responses to air quality risks and public health impacts.
