US AQI (PM2.5) by city
Values are calculated from DOE’s rounded API and a 24-hour PM2.5 average. Unknown or other dominant pollutants show as unavailable. How the conversion works

Malaysia air quality and haze today: Kuala Lumpur air quality and haze
The main number is PM2.5 US AQI calculated from Malaysia’s official Air Pollutant Index (API). We derive the 24-hour PM2.5 concentration from the rounded API and apply US thresholds. It is not an official all-pollutant AQI or a real-time NowCast.
The source API comes from the nearest DOE monitor within 75 km of the city centre. It is a station reading, not a city average. The app checks for updates every five minutes and shows the age of the observation.
The Petronas Twin Towers artwork is an illustration. The haze effect follows the API reading; it is not a camera view.
