Data-sharing work of the World Data Center for Geophysics, Beijing

The World Data Center (WDC) for Geophysics, Beijing, was founded in 1988. Supported by The Chinese Academy of Science and The Ministry of Science and Technology, our center has made much progress in recent years. The center has not only established the database to restore data which contain heat flow data, geomagnetic data, gravity data, etc. but also put them on the Internet (http://gp.wdc.cn) to provide free data service. The center has expended a great deal of effort to rescue the magnetograms observed 100 years ago by the Sheshan Observatory, the earliest geomagnetic observatory in China. The geophysics data of our center are abundant, and the way to get the data and information from the website is very simple and easily obtainable. In the future, the center will edit more data and construct a strong, convenient database in order to provide the better service to users.EI0SUPPL.S404-S407
