A NOTE ON THE AIR

A view, with a little context.

The picture interprets air quality. It is original artwork, rather than a live camera or a weather report.

24-hour PSI
NEA’s rolling 24-hour Pollutant Standards Index.
1-hour PM₂.₅
The measured concentration of fine particles, in µg/m³. This determines the illustrated haze band.
US AQI · estimated
A model estimate from Open-Meteo using the Copernicus Atmosphere Monitoring Service. The global model has approximately 45 km resolution; it is not a reading from a sensor at your address. Different indices and averaging periods can give different results.
Normal 0–55Elevated 56–150High 151–250Very high 251+

Bands use NEA 1-hour PM₂.₅ concentrations in µg/m³. A reading older than two hours is labelled as delayed. Each number is coloured by its own scale and includes its category label.

Location is used to select the nearest of Singapore’s five reporting regions. AQI requests use the region’s representative coordinates. If you are outside Singapore, choose a region manually. Your precise location is not stored.
