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

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.

Frequently Asked Questions

What is the main cause of air pollution in Nāhan?

Pollution in Nāhan is primarily driven by 13.3 km/h ESE winds, local traffic emissions, and industrial activity, which influence the current PM2.5 concentration of 59.0 µg/m³.

Is the AQI in Nāhan safe today?

Today's AQI is 153, which is categorized as Unhealthy (Sensitive). This means the air quality is unhealthy (sensitive) for the general population.
