The AQI Reports is available in three forms:

• Standard
• Current
• Range

The Standard AQI report calculates the AQI on a calendar day of data and presents the AQI calculation based on the full day of data and the defined AQI report programs. If multi-hour rolling averages are part of those programs, it may use data from previous / next days. Only one value is calculated for the day for each parameter.

The Current AQI report calculates an AQI value for each hour of the requested time range, using the defined AQI programs and applying the rolling average logic forward / backward based on that current hour.

The Range AQI report is like the Current report, but runs on a user-defined period of data.

Note that AirVision includes default AQI programs with forecasting logic (ozone surrogate and Conroy method for PM). If this is not desired, the feature can be disabled in the AQI Program Editor

Note also that the AQI report is run against a list of selected sites. AirVision will search each site for parameters whose EPA Parameter Codes and Unit Codes exactly match thos in the AQI programs. If a parameter does not appear in the AQI report, it is most likely because of a mismatch between these fields.
