空氣污染指數問題

I have checked very carefully and you may visit the website of Hong Kong Observatory http://www.hko.gov.hk/wxinfo/currwx/fndc.htm for some general information on the weather of each individual dates, but not including the Air Pollution Index.


The reason is API is not measured by HK Observatory, but our Environmental Protection Department!. I have checked and you can obtain the API index of each territory of the past days on the website below:


http://www.epd-asg.gov.hk/cindex.html


The further information can be searched from L.H.S. of the toolbar. It is very user-friendly.


Hope I can help you.
