Can AmbientWeather.Net Report Both AQIN And PM2.5?

Currently, at this time, no.

AQI is calculated individually for each pollutant. The overall pollutant with the highest AQI becomes the reported AQI. Since AmbientWeather.net only monitors (at this time) PM2.5, the only AQI value they could calculate would be the PM2.5 AQI. If, by chance, the PM10 AQI is higher than the PM2.5 AQI, then AmbientWeather.net would be reporting the wrong AQI value.

 

AQI, is a unitless index derived by the EPA.
