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 Nitrogen dioxide
Nitrogen dioxide is an acidic and highly corrosive gas. Nitrogen oxides are critical components of photochemical smog. Long-term exposure to high levels of nitrogen dioxide can cause chronic lung disease and affect the senses.
The guideline for Nitrogen dioxide is 0.08ppm (1hr avg).
Nitrogen dioxide is measured in parts per million.
