Remark:

(1) The AQHI information is based on raw data taken directly from EPD's Air Quality Monitoring Network.

(2) The hourly reported AQHI is for short term health risk communication; for health risks of long-term exposure of the air quality, please refer to Annual Air Quality Index (Annual AQI).

(3) In case of station or equipment suspension due to maintenance, the data collection for calculation of AQHI at station will be affected, the data of a most similar station will then be adopted. Such AQHI will be shown in italics.
