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 Ozone
Ozone is a colourless, highly reactive gas with a distinctive odour. The upper atmosphere ozone layer (at altitudes of 15–35km) protects the earth from harmful ultraviolet radiation from the sun. The ozone layer reduction represents a global atmosphere issue.
The guideline for Ozone is 0.1ppm (1hr avg) and 0.065ppm (8hr avg).
Ozone is measured in parts per million.
