Welcome to the Special Bureau for the Core (SBC).

The SBC is one of the eight Special Bureaus (SB's) of the Global Geophysical Fluids Center (GGFC), established by the International Earth Rotation Service IERS on January 1, 1998 to facilitate the link between the space geodetic and the geodynamic communities (see motivation). Within the GGFC, the SBC is responsible for collecting, archiving, and distributing data related to the core and plays a role in promoting and coordinating research on this topic. The SBC has about twenty members from the fields of geomagnetism, Earth rotation, geodynamo modelling (numerical and experimental), and gravimetry. Some background articles of the SBC can be found here).
