What happened (AQI Tracker information box)
A news report from The Indian Express describes an “AQI Tracker” information box that provides local air-quality readings and short impact notes for multiple locations. The AQI Tracker format presents location-wise categories/values and includes a summary about air quality status and impact for readers.
Background and earlier position (air-quality information communication)
Air-quality monitoring results are commonly communicated through an Air Quality Index (AQI). AQI is a simplified way to express air pollution levels as categories so that non-experts can interpret whether air conditions are likely to be harmful and adjust behaviour during poor-air episodes.
