Geodesy is the science of measuring the Earth’s shape, gravity field, and rotation. What if we could make it exciting, fun, and easy for everyone to understand? That’s exactly why the International Association of Geodesy (IAG) and its Global Geodetic Observing System (GGOS) launched the Geodesy Cartoons initiative: to bring geodesy closer to the public through visually engaging and humorous illust ...[Read More]
Highlights at IAG Scientific Assembly 2025 – What you need to know
It is almost time for the scientific assembly of the International Association of Geodesy (IAG), an association of the International Union of Geodesy and Geophysics (IUGG). The EGU Geodesy Division and the IAG have worked together for many years. For example, the IAG has been the main sponsor of the Geodesy Reception at past EGU General Assemblies. Besides this, the IAG coordinates global geodetic ...[Read More]
Combining GRACE and Kalman filter to get superior evapotranspiration estimates
Knowledge gaps in our understanding of the Hydrological Cycle The water cycle continuously provides us with fresh water. A critical process in the water cycle is evapotranspiration (ET), meaning that water evaporates from the surface and transpires from plants into the atmosphere. ET plays a crucial role in climate stability and the regulation of global water resources, but it is one of the most ...[Read More]
Geotandem: Exploring the subsurface of Mars using geodetic data
Welcome to the first of its kind, the Geotandem 01! A collaborative series between EGU divisions. Interdisciplinarity is intrinsic to Geosciences, so we want to showcase how researchers approach the same topics from different but also complementing perspectives. In each edition, we will bring you a high-interest topic for the community seen from the eyes of diverse disciplines. Today, the Tectonic ...[Read More]
