Traditionally geodesy is the science of the measurement and the mapping of the Earth’s surface. Since the surface is mainly shaped by the Earth’s gravity field the classical definition includes the Earth’s gravitational potential. Observing the Earth figure, the orientation and rotation as well as the gravity field, geodesy today provides spatial and temporal patterns of geophysical processes within the Earth system such as sea level rise, tides, melting of continental ice masses, changes in global water circulation and in the atmosphere or deformations of the solid Earth. Consequently, the geodesy division covers activities on the whole spectrum of modern geodetic Earth system modeling from the measurement systems to the investigation of geophysical processes.

Geodesy 101 Literature

During this year’s EGU General Assembly (GA) we held the first Geodesy 101 Short Course, where we gave an introduction to satellite gravimetry, GNSS processing and geodetic reference frames. We want to thank all of you who attended in-person or virtually, and made the short course a great experience! Please provide us feedback, if you have attended the short course here. At the GA, we were only able to scratch the surface of each topic, but there are a number …


The comprehensive Geodetic Information Portal of GGOS

The Global Geodetic Observing System (GGOS) of the International Association of Geodesy (IAG) is a collaborative contribution of the global geodesy community to the observation and monitoring of the Earth System. Geodesy is the science of determining the shape of the Earth, its gravity field, and its rotation as functions of time. Essential to reaching this goal are stable and consistent geodetic reference frames, which provide the fundamental layer for the determination of time-dependent coordinates of points or objects, and …


What’s up for geodesy during the upcoming EGU22?

It’s this time of the year again where we all try to meet up in Vienna and talk about our latest scientific results and more importantly network with old and new colleagues. The EGU General Assembly (GA) will be a hybrid meeting this year: EGU22. There will be scientific sessions with short oral presentations, networking opportunities and short courses. All scientific sessions and most short courses will be accessible online as well. Several networking opportunities are planned for in-person attendees …


Geodesists on Tour: GNSS measurements in East Africa

Africa hosts the world’s most extensive subaerial rift system on Earth known as the East African Rift System (EARS). It stretches over 5000 km from the Red Sea and Gulf of Aden intersection in the north to the Southwest Indian Spreading Ridge south of South Africa. East-West, the EARS spans the eastern border of the Democratic Republic of Congo across to eastern Madagascar over 3000 km. The process of continental rifting involves rupturing the entire thickness of the lithosphere, and …

Current issue of the EGU newsletter

The August issue of The Loupe explores how existing energy resources inform climate change mitigation. Scientists from the Environmental Defense Fund find that while hydrogen is certainly part of the solution to get to net zero, this fuel of the future may not be as clean as we think. Researcher in energy transition under climate change Jarmo Kikstra discusses the delicate intersections between social and natural sciences, and on World Biofuels Day we look at commercially available biofuels around the world and some new ones under development.

Also in this issue: the EGU Biodiversity Task Force’s seven recommendations to the EU Nature Restoration Law which will now be amended and either passed or rejected by the European Parliament and The Council of the European Union. Finally, apply by 12 September to the EGU Policy Pairing scheme to spend a week in Brussels with a Member of the European Parliament (MEP).
