What this is, and is not

Read the figures with this in mind.

Each region’s figure is the highest reading among its monitoring stations in that hour, never an average — averaging would hide a genuinely bad station behind clean ones nearby. A region with one reporting station is therefore described by that station alone, and the station is named above so you can judge how representative it is.

These are US EPA AQI values published through the World Air Quality Index network. Malaysia’s Department of Environment publishes a separate Air Pollutant Index through APIMS on different breakpoints, so the official figure for this day will not match the numbers here. Nothing on this page constitutes an official haze declaration or a health directive.

A region appears only if we hold readings for it on this day. An absent region may have had clean air, or may simply have had no station publishing.
