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).
- Current PM2.5: 78.2 ยตg/mยณ
- Calculation: Your city falls into the "Unhealthy" category (Category 4).
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.
