The Local Air Quality Index - Switzerland
The Local Air Quality Index is a method used by the government and companies to communicate air quality in an understandable way.
How we calculate the air quality index - Switzerland
BreezoMeter uses an index called “KBI (CH)”
We take the average of each pollutant type according to local government definitions.
An official conversion table is used to convert average pollutant concentrations to AQI for each pollutant.
The final AQI is determined by taking the worst AQI among all pollutants. The worst pollutant being the dominant pollutant.
