Station overview—Brisbane CBD
Air quality monitoring in the Brisbane CBD began in 1995 at a site in an elevated position at the Queensland University of Technology's Gardens Point campus.

About air quality categories
Air quality categories are used to make it easier to interpret air quality data by reducing the complexity associated with different pollutant concentration units and air quality guideline values.
Each air quality measurement from a monitoring station is assigned an air quality category rating based on comparison of the measurement value against the relevant air quality guideline. Five colour-coded air quality categories are used, being ‘Good’ (green), ‘Fair’ (yellow), ‘Poor’ (orange), ‘Very poor’ (red) or ‘Extremely poor’ (dark red). Values greater than the air quality guideline will be appear as ‘Poor’, ‘Very poor’ or ‘Extremely poor’.
About these parameters
- Particle PM2.5
Airborne particles less than 2.5 micrometres in diameter, referred to as PM2.5, can be hazardous to human health or cause a nuisance when present in the air at elevated levels. They are capable of penetrating the lower airways of humans and can cause possible negative health effects.
The guideline for Particle PM2.5 is 50µg/m³ (1hr avg) and 25µg/m³ (24hr avg).
Particle PM2.5 is measured in micrograms per cubic metre.
- Particle PM10
Airborne particles less than 10 micrometres in diameter, referred to as PM10, can be hazardous to human health or cause a nuisance when present in the air at elevated levels. They are capable of penetrating the lower airways of humans and can cause possible negative health effects.
The guideline for Particle PM10 is 100µg/m³ (1hr avg) and 50µg/m³ (24hr avg).
Particle PM10 is measured in micrograms per cubic metre.
- Visibility
Aerosols and fine particles can reduce visibility. Smoke from fires or haze are common causes of poor visibility.
The guideline for Visibility is 235Mm⁻¹ (1hr avg).
Visibility is measured in inverse megametres.
