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.


2015 IUGG General Assembly in Prague, Czech Republic
The Institute of Geophysics of the Academy of Sciences of the Czech Republic and the Czech National Committee of Geodesy and Geophysics will host the XXVI General Assembly of the International Union of Geodesy and Geophysics (IUGG) from June 22 to July 2, 2015. This multi-disciplinary conference will cover the topics of all eight scientific associations of the IUGG. Conference details can be found on the XXVI IUGG General Assembly website

IUGG Early Career Scientist Awardees
On November 5, 2014, ten scientists were given IUGG Early Career Scientist Awards for their outstanding research in Earth and space sciences and for their international research cooperation. The USNC/IUGG would like to congratulate the two awardees from the United States: Gregory Foltz (Oceanography) and Ben Kravitz (Atmospheric Sciences). The awards will be presented at the 26th IUGG General Assembly in Prague, Czech Republic, during an Honor ceremony. For more details, please consult the IUGG news release (PDF).

National Academy of Sciences, Royal Society Release Joint Publication on Climate Change
The U.S. National Academy of Sciences and the Royal Society, the national science academy of the U.K., released a joint publication that explains the clear evidence that humans are causing the climate to change, and that addresses a variety of other key questions commonly asked about climate change science. For more details and a link to the full report, please consult the Climate Change: Evidence and Causes press release.


2014 AAAS Symposium - “Santa’s Revenge: The Impacts of Arctic Warming on the Mid-Latitudes” - February 15, 2014
This symposium examined high-latitude changes linked to mid-latitude weather and the effect of these complex phenomena on freshwater resources, food availability, and national security. This event was spearheaded by the U.S. National Committee for Geodesy and Geophysics, and co-sponsored by the U.S. National Committees for INQUA, Soil Sciences, and Geological Sciences.

An audio file of the symposium, the presentations given by each speaker, and a more complete list of media coverage can be found on the 2014 Santa's Revenge archive page.

Workshop on Mathematics of Climate Change, Related Natural Hazards and Risks
The Workshop on “Mathematics of Climate Change, Related Natural Hazards and Risks” was held at CIMAT in Guanajuato, Mexico, 29 July - 2 August 2013. The workshop brought together about 40 young researchers, mainly from Latin America and the Caribbean and a dozen distinguished scientists, each of which gave several lectures on a chosen topic. The workshop was part of the world initiative “Mathematics of Planet Earth 2013” ( It was jointly organized by the International Mathematical Union (IMU), the International Union of Theoretical and Applied Mechanics (IUTAM), and IUGG. It was sponsored by the International Council of Industrial and Applied Mathematics (ICIAM) and partly funded by a grant from the International Council for Science (ICSU). It is supported by the ICSU Regional Office for Latin America and the Caribbean (ROLAC), the Integrated Research on Disaster Risk (IRDR), the World Climate Research Program (WCRP), the U.S. National Academy of Sciences, and the Academia Mexicana de Ciencias, and CIMAT (Centro de Investigación en Matemáticas). The members of the Scientific Committee are Susan Friedlander (IMU), Ilya Zaliapin (IUGG) and Paul F. Linden (IUTAM). More details are available on the following website:

2013 AAAS Symposium - "U.S. Climate and Weather Extremes: Past, Present, and Future"
The symposium was sponsored by the four USNCs for the Earth Sciences and spearheaded by the U.S. National Committee for the International Union for Quaternary Research. This session provided both current and paleoclimatic perspectives on the nature of recent extreme climate and weather events and their societal and ecological impacts, with a focus on the United States. The symposium was held February 15, 2013 at the AAAS meeting in Boston, Massachusetts. For more information about this meeting, including audio of the presentation and press coverage, please visit the 2013 AAAS Symposium website
