The UK IUGG National Committee is sponsored by the Royal Society and is Chaired by Professor David Collins (University of Salford). The International Union of Geodesy and Geophysics (IUGG) is an international organization dedicated to advancing, promoting, and communicating knowledge of the Earth system, its space environment, and the dynamical processes causing change. The Committee has 9 members selected from the UK science community to represent the associations that make up the IUGG and the UK parent organisations that sponsor these associations.
