Remarks:

(1) Time shown is in Hong Kong time.

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

(3) 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 the Annual Air Quality Index(Annual AQI).

(4) In case of equipment or station suspension due to repair and maintenance, the data collection for calculation of AQHI at station will be affected, the data of similar stations will then be adopted. Such AQHI will be shown with an asterisk.
