The 28^th IUGG General Assembly was be held from 11-20 July 2023 at the Messe Berlin – City Cube, Berlin, Germany. This was a special opportunity for participants from around the world to come together and share their science and culture. A wide range of scientific activities were offered, including special public lectures, Union keynote lectures and a variety of thematic sessions.

The workshop on "Earth Science data Analysis - Getting it right by keeping it real" took place from 22^nd to 24^th February 2023 at GFZ German Research Centre for Geosciences and was organized by Gert Jan Weltje (KU Leuven), Kai Hartmann (FU Berlin), Anne Bernhardt (FU Berlin), Arne Ramisch (U Innsbruck), and Rik Tjallingii (GFZ Potsdam).

Short Summary
Quantification of analytical data is crucial part of data analysis in Earth sciences, and require a correct mathematical, physical and statistical approach to ensure sound and robust results. Negative chemical concentrations, sediment ages reaching into the future, and conclusions based on intrinsic correlations appear to be an unavoidable byproduct of data analysis in the Earth Sciences. Such impossible predictions arise from inappropriate statistical model generation.
In a three-day course, examples and methods were presented on how to avoid these (and many other) common mistakes. The was to provide a simple, logical, and effective recipe for statistical model generation in geochemistry, mineralogy, petrology, geomorphology, paleoenvironmental analyses and paleoclimatology. Equipped with this knowledge, participants should learn to avoid common statistical pitfalls and be able to generate models that are mathematically and physically meaningful.

The DEUQUA-conference 2022 is organised by the German Quaternary Association (DEUQUA – Deutsche Quartärvereinigung) and the Section Climate Dynamics and Landscape Evolution of the GFZ Potsdam and will take place in Potsdam from 25 to 29 September 2022. 

One focus of this conference is new approaches to the integration and synchronisation of terrestrial and marine geoarchives in order to investigate regional differences in Quaternary climate and environmental changes with greater precision. Further topics of the conference are climate in warm phases of the Quaternary, as well as anthropogenic influences in sedimentary archives and geomorphological processes as a consequence of climate and environmental change. In addition, a special session on applied and regional Quaternary geological topics will be offered. Lecture and poster sessions will be introduced with keynote lectures. The programme also includes pre- and post-excursions and a public evening lecture.

The 31^st Hydrogeology PhD Day took place 20^th - 22^nd July 2022 in Potsdam and was organized by the PhD students of the sections Geoenergy and Fluid Systems Modelling of GFZ Potsdam as well as of the Institutes of Hydrogeology of FU Berlin and Engineering Geology of TU. The event was hold as an in-person event with excursions to the surrounding area and workshops during the three days in addition to the presentations of the PhD students.

The 7^th International Meeting on Heat Flow and the Thermal Structure of the Lithosphere was from June 20-22, 2022 in Potsdam, Germany, hosted by the GFZ German Research Centre for Geosciences. The meeting renewed the successful tradition of the Czech "castle meetings", which were organized by the Geophysical Institute of the Czech Academy of Sciences in the years from 1982 to 2006. In honor of the chairman of those meetings, the name Čermák is adopted now for the conference series and the meetings ahead, organized under the auspices of the IHFC.

The 1^st workshop on “Data Science for GNSS Remote Sensing” took place on the historic “Telegrafenberg” in Potsdam on June, 13-15, 2022 and washosted by the German Research Centre for Geosciences GFZ.

There has been recently a rapid progress in Earth observation using GNSS signals from numerous ground and satellite based platforms as well as modern data scientific approaches for their analysis, including machine learning and data assimilation techniques. We believe it is the right time to gather scientists interested in interdisciplinary activities linking these two research areas to foster a creative and intense scientific exchange and collaborations. Our ultimate goal is the provision of advanced and versatile GNSS Remote Sensing data products on different spatio-temporal scales for Earth System science and related operational applications to advance early warning systems and numerical weather forecasts.

The EGU Galileo conference “Fire impacts at the Earth surface across space and time and perspective for future fire management” was held in Bad Belzig, Germany and Online on 28^th March - 1^st April 2022.

This Galileo conference aims to provide a discussion-driven meeting to facilitate knowledge transfer between fire science disciplines and to identify research needs to support fire management of the future. Leading fire experts together with scientists and stakeholders from the fire and forest policy and management domains will discuss in plenary and breakout sessions 1) new joint perspectives on key processes, drivers and impacts of fire in the natural and human-shaped environments and 2) identify major gaps in socially relevant and actionable knowledge to guide future fire research. Participants will preferably represent different fire disciplines, temporal and spatial scales, career phases and regional foci.

The workshop on "Analysis of Earth-science data: getting it right by keeping it real" took place from 6^th to 8^th April 2022 at FU Berlin and was organized by Gert Jan Weltje (KU Leuven), Kai Hartmann (FU Berlin), Anne Bernhardt (FU Berlin), Rik Tjallingii (GFZ Potsdam) and Arne Ramisch (GFZ Potsdam).

Short Summary:
Negative element concentrations and sediment ages reaching into the future? Impossible predictions appear to be an unavoidable byproduct of data analysis in the Earth Sciences. If you are an undergraduate student, PhD, or postdoc, and are curious to know how you can avoid these (and many other) common mistakes, this workshop is for you. Our objective is to offer a simple, logical, and effective recipe for statistical model generation in the Earth Sciences, aimed at avoiding many common errors. Armed with this knowledge, you will be able to generate mathematically, physically, and statistically meaningful models. We will start from the basics: mathematical and statistical knowledge at university entry level is sufficient to follow the workshop. In the first part, we will introduce the principles of successful model building using simple examples. In the second part, we will develop these into more advanced models. In this part, we will focus on prediction of sediment properties from core data. We will explain the advanced methods at a conceptual level only, to illustrate the opportunities offered by our approach.
