| Launch of Data Collection or Production Centre (DCPC) for World Weather Information Service |
| Notification from Hong Kong Observatory (HKO) |
The Hong Kong Observatory announces that the Data Collection or Production Centre (DCPC) for the World Weather Information Service (WWIS) has moved to the operational phase effective 15 May 2014.
The WWIS at http://worldweather.wmo.int is a web site operated by HKO on behalf of the World Meteorological Organization (WMO). It serves as a centralized source on the Internet of the official weather information issued by the National Meteorological and Hydrological Services (NMHSs). By April 2014, a total of 166 WMO Members supplied weather forecasts or climatological data for showing on the WWIS. As an integral component of the WMO Information System (WIS), the DCPC for WWIS serves three major functions:
| 1. |
Provide online services for global users to search and access the official weather forecasts and climatological information for cities around the world collected under the WWIS programme. |
| 2. |
Offer subscription service for users to automatically receive weather information of their interest. The information is encoded in XML format to facilitate further data processing. |
| 3. |
Provide metadata of the weather information available at the DCPC for WWIS to the Global Information System Centres (GISC) under the WIS framework to enable searching of weather information through the GISC’s Discovery, Access and Retrieval (DAR) services. |
From the DCPC for WWIS portal (http://dcpc.worldweather.org), users can search for weather forecast and climatological information products currently available under the WWIS programme. They can request direct access to the most recent issues of the products or set up a subscription to get the products delivered once they arrive at the DCPC (please refer to the user guide in the Appendix). The web portal is open to all participating NMHSs of the WWIS programme.
For more information about the service of DCPC of WWIS, please contact Mr. CHAN Sai-tick, Forecast Systems Division, Hong Kong Observatory at email: dcpc@hko.gov.hk.
