The 28th IUGG General Assembly (IUGG2023 GA) will be held from 12 to 19 July 2023at the City Cube in Berlin, Germany. The IUGG GA is one of the world’s most important geoscientific events, with more than 5000 participants. It takes place every four years. The 28^th General Assembly will be organized by GFZ and will therefore be a special occasion for GFZ and its international partners to present their common research.

After more than two years of online/hybrid scientific meetings this General Assembly is a special opportunity for participants from around the world to meet again. The full range of geodetic and geophysical themes will be discussed including atmospheric, oceanographic, hydrological, and cryospheric sciences. Our program will further enhance the important interdisciplinary collaboration for a better understanding of our Earth System.

IUGG 2023 will provide a platform for personal meetings, exchange of ideas and developing new concepts for international science collaboration, all of which have suffered a setback during this pandemic crisis. IUGG 2023 will help to create a new spirit to address large societal challenges such as global environmental change and natural hazards and to stimulate novel geoscience research.

The Berlin-Brandenburg region is home to one of the largest geoscientific clusters in the world. Participants will have a unique opportunity to meet their international project partners again in person or to combine their participation with a visit to the reseach organizations GFZ, AWI or DLR. We are planning a prominent excursion program, and especially for young scientists we would like to provide opportunities for exchange, presentation, and discussion in addition to the official agenda.
