Probing Earth’s Deep Interior Using Space Observations Synergistically

During the recent decades, space missions (e.g., CHAMP, GOCE, GRACE and Swarm) have been developed by space agencies in Europe and the USA to measure the Earth's gravity and magnetic fields and their spatio-temporal variations. These successful missions have already provided a wealth of groundbreaking results about the permanent and time-variable gravity and magnetic fields of the Earth. However, more can be learned about the Earth's structure by combining data of the gravity and magnetic fields, together with Earth's rotation data routinely measured using space geodesy techniques, as well as with the most up-to-date modelling of the Earth's internal structure. Use in synergy of these global observables and model data represent a unique way to further investigate the physics of the deep Earth's interior. In addition, to the well-known correlation between Earth's rotation and magnetic field observed at interannual and decadal time scales, recent studies have reported unexpected correlation between spatio-temporal changes of the gravity field and magnetic field, also at interannual time scale, that may result from processes occurring in the liquid core and at the core-mantle boundary. This book gathers a series of chapters that provide state-of-the art overviews on the gravity field, magnetic field and Earth's rotation observations, and on their interpretation in terms of the deep Earth's structure, as well as on core dynamics and processes at the core-mantle boundary.

The chapters 'Gravity Variations and Ground Deformations Resulting from Core Dynamics', 'Rapid Variations of Earth's Core Magnetic Field', 'A Dynamical Prospective on Interannual Geomagnetic Field Changes', 'Core Eigenmodes and their Impact on the Earth's Rotation', 'Earth's Rotation: Observations and Relation to Deep Interior', 'Interiors of Earth-Like Planets and Satellites of the Solar System', 'Correction to: Interiors of Earth-like planets and satellites of the Solar System', 'Fluid Dynamics Experiments for Planetary Interiors', 'Structure, Materials and Processes in the Earth's Core and Mantle', 'Correction to: Structure, Materials and Processes in the Earth's Core and Mantle' and 'Applications and Challenges of GRACE and GRACE Follow-On Satellite Gravimetry' are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Veronique Dehant works at the Royal Observatory of Belgium, where she is responsible for the Operational Directorate "Reference Systems and Planetology". She is also Extraordinary Professor at the Catholic University of Louvain (UCLouvain). She is an Academician (Member of the Royal Academy of Belgium, Science Class) since 2010, Foreign Member of the Paris Academy of Sciences since 2016 and has been awarded several prizes including the Descartes Prize of the European Union in 2003 and she has just been awarded the De Leeuw-Damry-Bourlart Prize, Prize in Fundamental Exact Sciences among the five FNRS research excellence prizes. In 2015 and 2020, she obtained an Advanced Grant and a Synergy Grant from the European Research Council. She is involved in processing data from instruments in several space missions, in particular of the RISE experiment (Rotation and Interior Structure Experiment) on board the InSight mission (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) currently on the surface of Mars.

Anny Cazenave is director for Earth sciences at the International Space Science Institute, Bern, Switzerland and emeritus scientist at the 'Laboratoire d'Etudes en Géophysique et Océanographie Spatiale', Toulouse, France. Her research deals with the applications of space techniques to geosciences (geodesy, solid Earth geophysics, sea level change and climatic causes, land hydrology from space).

Lorena Moreira earned her PhD of Science in Physics from the University of Bern (Switzerland), studying temporal variability and climate induced changes on middle atmospheric ozone measured by a ground-based microwave radiometer (GROMOS) located at Bern. She has coauthored over 10 publications including Atmospheric Chemistry and Physics, Earth Planets and Space, Global and Planetary Change, Remote Sensing, Surveys in Geophysics, etc. Lorena Moreira is a postdoctoral fellow at the International Space Science Institute (ISSI, Bern, Switzerland) under the supervision of Dr. Anny Cazenave. Her current research focuses is on the study of variability of altimetry-based sea-level rise at global and regional scale and the influence of the sea-level budget components.
