  • Christina Strohmenger defended her PhD on "Large-scale mass redistribution in the Earth system from synergistic use of Swarm data". (10.12.2021).

  • DFG decided to establish a new collaborative research centre (SFB1502) at Uni Bonn, with the focus on understanding the role of land use in regional climate change. IGG groups will developing new ways of integrating GRACE/-FO data in coupled ESMs, analyzing radar altimetry, SWOT cal/val, integrating ocean data and models, new deep learing techniques for remote sensing, and developing innovative RDM infrastructure. Read more (25.11.21).

  • Our retired colleague and former chair of the group, Prof. Karl Heinz Ilk, published a wonderful, modern textbook on physical geodesy, satellite geodesy, reference systems in geodesy (Grundlagen der Physikalischen und Mathematischen Geodäsie, 6 volumes, in German, Springer). (19.11.21).
