The World Data Centers (WDCs) were established in the International Geophysical Year of 1957-1958 (IGY) based on the recommendation from the International Council of Scientific Unions (now International Council for Science) to guard against catastrophic loss of data, and for the convenience of data providers and users.

National Institute of Information and Communications Technology (NICT)has taken charge of the WDC for Ionosphere. NICT has collected and archived the ionospheric data and metadata provided by various ionospheric observatories in the world (approximately 250 stations). These ionospheric data have been exchanged with other WDCs and been open to the public.
