AQ Indexes

What is an air quality index (AQI)?

An air quality index (AQI) is the scale by which a certain provider—for example, the U.S. EPA—categorizes different air quality levels, based on different calculation methods, data sources, and designated purposes.

Supported AQIs

The Air Quality API includes over 70 air quality indexes.

Based on the request parameters, for each location and timestamp (up to) two air quality indexes can be returned in the code field of the response body:

  • Universal AQI. This AQI is returned if the universalAqi boolean is set to true.
  • A local AQI defined for the requested location. A Local AQI is returned if the LOCAL_AQI extra computation is specified. Note that each supported location may have several local AQIs available and it is possible to modify the default local AQI using the customLocalAqis parameter.

The following table lists the index ranges, categories, and pollutants for each AQI surfaced by the Air Quality API.
