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.

(4) Owing to the maintenance work on the roof of the building where the Tuen Mun monitoring station is located, the operation of  the Tuen Mun station will be temporarily suspended from 1 November 2014 for a few months. We apologize for any inconvenience caused.
