World Data Center for Ionosphere and Space Weather
The ICSU World Data System (WDS) was created through a decision of the General Assembly in 2008, restructuring the former ICSU World Data Centers (WDCs) established during the International Geophysics Year (IGY) of 1957-1958 and former Federation of Astronomical and Geophysical data-analysis Services (FAGS). WDS aims to ensure the long-term stewardship and provision of quality-assessed data and data services to the international science community in order to support the scientific research projects ICSU actively promotes.
National Institute of Information and Communications Technology (NICT) has been operating a Regional Warning Center (RWC) of the International Space Environment Service (ISES). We also hosted and operated the WDC for Ionosphere under the auspices of ICSU WDC. Recognized for these contributions to international data-sharing efforts, the WDC for Ionosphere and Space Weather operated by NICT has been officially accepted as a Regular Member of ICSU WDS. Our organization collects and archives data and information on ionosphere and space weather, and makes them available to the public. Published data are used by a wide range of users including public organizations, research institutions, and universities.
