  • New paper by Kerstin Schulze et al on the joint assimilation of GRACE/-FO and observed streamflow data into hydrological models. Read more (17.10.2024).

  • The University of Bonn has become an official Partner of the United Nations Global Geodetic Centre of Excellence (UN-GGCE). Read more about the UN-GGCE (04.07.2024).

  • Kristin Vielberg defended her PhD on "Thermosphere and radiation effects in forward and inverse non-gravitational force modelling" (12.01.24).

  • New paper by Helena Gerdener et al. on the assimilation of GRACE and GRACE-FO data into a global hydrological model, with data published on PANGAEA. Read more (31.8.2023).

  • The group's transportable iGrav superconducting gravimeter has been installed at the Todenfeld observatory and first measurements of time variations of g have been successfully collected (22.11.2022).

  • 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).
