About air quality index values

Our scientists create an air quality index by converting measured pollutant concentrations into index values which make it easier to interpret air quality data by reducing the complexity associated with pollutant concentrations.

The index value is the pollutant concentration expressed as a proportion of the National Environment Protection Measure for Ambient Air Quality (Air NEPM) standard or the Environmental Protection (Air) Policy 2008 (Air EPP) objective.

About Visibility

Aerosols and fine particles can reduce visibility. Smoke from fires or haze are common causes of poor visibility.

The standard/guideline for Visibility is 235Mm⁻¹ (1hr avg).
