Remark:

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

(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 equipment maintenance, the monitoring of RSP and FSP at Sha Tin general station is temporarily suspended. We apologize for any inconvenience caused.

(5) Owing to equipment quality assurance checking, the monitoring of FSP at Tuen Mun general station is temporarily suspended from 29 August to 1 September 2016.  We apologize for any inconvenience caused.
