The Observatory enhances its Website with
Ultraviolet-A (UVA) Radiation Information (23 March 2011)

The Hong Kong Observatory today (23 March) starts providing real-time UVA radiation data on its webpage, so that the public can better appreciate the ultraviolet (UV) radiation in Hong Kong.

UVA radiation is a major component of the solar radiation. Over-exposure to UVA radiation may cause wrinkling, ageing and tanning of the skin, as well as potential development of skin cancer. As there is increasing concern about the health effect of UVA radiation, the Observatory has set up equipment to measure UVA radiation intensity at the King's Park Meteorological Station.

Apart from real-time UVA radiation data, relevant information including the characteristics of UVA radiation, its health effect and sun protective measures, etc, are available on the Observatory's webpage. Members of the public are welcome to visit the webpage at:  The latest report and forecast of the UV index are available through the Observatory's website, radio and Dial-a-Weather system (1878200).
