International Centre for Global Earth Models The International Centre for Global Earth Models is an international research institute that coordinates development of global geophysical models and datasets for Seismology, Geodesy, Geophysics and related Earth science applications. It serves as a hub for model building, data integration, and community standards involving international agencies such as the United Nations, professional bodies including the American Geophysical Union and the European Geosciences Union, and major observatories like the United States Geological Survey and the British Geological Survey. The centre works with universities, national laboratories, and nongovernmental organizations across continents including partners in Japan, India, China, Australia, Canada, Germany, France, Italy, Spain and Brazil.

History

The centre emerged from early-21st-century initiatives inspired by programs such as the Global Seismographic Network, the Global Geodetic Observing System, and collaborative projects under the Intergovernmental Oceanographic Commission and International Union of Geodesy and Geophysics. Founders included scientists affiliated with the Massachusetts Institute of Technology, California Institute of Technology, ETH Zurich, University of Cambridge, University of Tokyo, Peking University and Australian National University. Early collaborations referenced standards from the International Association of Seismology and Physics of the Earth’s Interior and lessons from multinational efforts like the International Continental Scientific Drilling Program and the World Climate Research Programme. As the centre matured it coordinated model releases during major events such as the 2004 Indian Ocean earthquake and tsunami, the 2011 Tōhoku earthquake and tsunami and the 2015 Nepal earthquake, collaborating with agencies including National Aeronautics and Space Administration, European Space Agency and National Oceanic and Atmospheric Administration.

Mission and Objectives

The centre’s mission aligns with goals set by bodies such as the Group on Earth Observations, the World Meteorological Organization and the International Telecommunication Union for interoperable, open-access scientific resources. Core objectives mirror priorities in reports by the Intergovernmental Panel on Climate Change, the UN Office for Disaster Risk Reduction, and the Committee on Earth Observation Satellites: produce community-vetted global Earth models, enable reproducible research adopted by the Royal Society and the National Academy of Sciences, and support operational services used by International Atomic Energy Agency-linked monitoring and regional nodes of the Global Seismographic Network.

Organizational Structure and Governance

Governance is structured around a board with representation drawn from institutions such as the European Commission, World Bank research units, and national academies including the Russian Academy of Sciences and the Indian Academy of Sciences. Scientific advisory committees include experts from Scripps Institution of Oceanography, Lamont–Doherty Earth Observatory, Institut de Physique du Globe de Paris, Max Planck Society institutes, and the Korea Institute of Geoscience and Mineral Resources. Administrative operations integrate policy frameworks from the International Labour Organization-style charters and procurement practices consistent with Organisation for Economic Co-operation and Development guidelines. Funding partners historically include grant agencies like the National Science Foundation, the European Research Council and philanthropic organizations such as the Bill & Melinda Gates Foundation for capacity projects.

Scientific Programs and Research Areas

Programs span seismological waveform inversion used in methodologies pioneered at California Institute of Technology and Imperial College London, mantle convection modeling influenced by work at Princeton University and ETH Zurich, and crustal deformation studies aligned with Jet Propulsion Laboratory and GFZ German Research Centre for Geosciences initiatives. Research areas include global seismic tomography, normal mode analysis, mantle rheology, post-glacial rebound studies tied to Paleoclimatology outputs used in National Oceanography Centre syntheses, and earthquake source physics collaborating with teams at Seismological Society of America centers. Specialist groups also address ocean-bottom seismology with partners including the Ocean Observatories Initiative and tsunami modeling with institutions such as the Pacific Tsunami Warning Center.

Data and Model Products

The centre curates interoperable datasets and model releases following metadata conventions used by International Organization for Standardization and Digital Object Identifier practices common at major data repositories like PANGAEA and EarthRef. Products include global shear-wave velocity models, full-waveform inversion suites, anisotropy maps, crustal thickness compilations, and geoid and gravity field models compatible with Gravity Recovery and Climate Experiment and GRACE Follow-On time series. Distribution mechanisms align with standards employed by Global Change Data Lab and archiving norms of British Antarctic Survey and National Centers for Environmental Information.

Collaborations and Partnerships

Partnerships span intergovernmental organizations such as the United Nations Educational, Scientific and Cultural Organization and the International Council for Science, regional science networks like the African Union research programs and the Association of Southeast Asian Nations science initiatives, and consortia including the Consortium of Universities for the Advancement of Hydrologic Science. The centre coordinates joint projects with technical partners including Google research teams, cloud services from Amazon Web Services and Microsoft Research, and high-performance computing facilities at Argonne National Laboratory, Oak Ridge National Laboratory and CERN. It also engages with standard-setting groups such as the Open Geospatial Consortium and community platforms like GitHub for model dissemination.

Outreach, Training, and Capacity Building

Training programs involve short courses and workshops hosted with universities like University of Oxford, Harvard University, University of São Paulo, and University of Cape Town, and regional training nodes modeled after programs run by International Atomic Energy Agency and World Health Organization technical training centers. Capacity-building initiatives collaborate with development agencies including United States Agency for International Development and Deutsche Gesellschaft für Internationale Zusammenarbeit to support national seismic networks, hydroacoustic arrays, and satellite data utilization in low-resource settings. Public outreach leverages partnerships with museums and science centers such as the Smithsonian Institution and the Natural History Museum, London to promote awareness of Earth system science.
