IAG ICC on “Geodesy for Climate Research”
During the IUGG General Assembly in Montreal the IAG Executive Committee (EC) established a new IAG Inter-Commission Committee on "Geodesy for Climate Research" (ICCC) to enhance the use of geodetic observations for climate studies. The goal is to establish a systematic and comprehensive approach among the various geodetic communities, but also to establish and foster links to climate science.
