How is this AQI calculated?

The primary Air Quality Index (AQI) shown above is calculated using the US EPA Linear Interpolation formula based on PM2.5 concentration (Fine Particulate Matter).

Formula: Ip = [(Ihi - Ilow) / (Chi - Clow)] * (Cp - Clow) + Ilow

Current PM2.5: 14.8 µg/m³
Calculation: Your city falls into the "Good" category (Category 1).

Note: While several pollutants (O3, NO2, SO2) are monitored, PM2.5 is used as the primary "driver" for the main index value as it typically represents the highest health risk.
