U.S. National Committee for Geodesy and Geophysics

The U.S. National Committee for Geodesy and Geophysics (USNC/IUGG) promotes the advancement of geophysical and geodetical sciences in the United States and throughout the world by participating in the activities of the International Union of Geodesy and Geophysics (IUGG).

The USNC/IUGG serves to advance geodesy and geophysics in the United States and throughout the world by:

  • Representing the interests of the U.S. sciences community in all activities of the International Union of Geodesy and Geophysics (IUGG) and its eight component Associations on behalf of the National Academy of Sciences (NAS), the U.S. adhering body to the IUGG.
  • Fostering collaborative research through the organization and sponsorship of scientific sessions and meetings in the U.S. and abroad.
  • Encouraging and supporting participation and service by U.S. scientists in international bodies organized under the IUGG and its Associations.
  • Sending voting delegates as representatives of the U.S. geophysical community to IUGG-sponsored international congresses and General Assemblies.
  • Supporting the engagement of early career U.S. scientists in international scientific activities and organizations.


Former USNC/IUGG Chair Elected to IUGG Finance Committee
The U.S. National Committee for IUGG congratulates Priscilla Grew, former USNC chair, on her recent election to the IUGG Finance Committee. Dr. Grew served as USNC chair from 2003-2011, and is currently Professor Emerita of Earth and Atmospheric Sciences at the University of Nebraska, Lincoln.

Celebrating 100 Years of the IUGG

Formed in Brussels, Belgium, on 28 July 1919, the International Union of Geodesy and Geophysics (IUGG) celebrates its 100th anniversary in 2019. The centennial year marks an important milestone for IUGG. Since its inception as a union of international scientific associations, IUGG has evolved into a prominent scientific organization promoting Earth and space sciences worldwide in the complex political, economic and scientific landscapes of the 20th and the beginning of the 21st centuries. IUGG’s mission is to advance, strengthen and promote Earth and space sciences for the benefit of humanity through international research cooperation and education, and to communicate the knowledge to governments and policymakers. For the decades ahead, IUGG envisions a future Earth that is environmentally sustainable and where societies are resilient against natural hazards.

To celebrate the Centennial of the Union, IUGG established a Task Force to develop a program for celebrations around the world for 2018-2019. In 2018, several conferences/symposia and a summer school for early career scientists were held in China, Japan, Mexico, Turkey, and the USA, including a USNC/GG Centennial Symposium at AGU 2018. The program for 2019 includes:
-    27th IUGG General Assembly, Montreal, Canada, 8-18 July 2019;
-    Celebration of the IUGG Centennial at UNESCO, Paris, France, 29 July 2019;
-    Several meetings in Europe, South America, and the Middle East;
-    A special volume on “The International Union of Geodesy and Geophysics: From Different Spheres to a Common Globe” will be published as a part of the peer-reviewed journal History of Geo- and Space Sciences.

As a part of this program, a website dedicated to the IUGG Centennial has been developed and is now open to the public. Please visit to learn more about the history of IUGG. We hope all visitors to the website, especially IUGG scientists from all nations and geoscientific disciplines, will enjoy this wonderful 100-year journey through space and time and appreciate the work of several generations of Earth and space scientists, who voluntarily contributed their time and efforts to the development of international cooperation in geosciences. Note: This text was co-authored by IUGG President Michael G. Sideris, and IUGG Secretary-General Alik Ismail-Zadeh.

A special issue on the history of IUGG has been recently published by the journal of History of Geo-and Space Sciences, available at
