About this Research Topic
Today, following advances in technology, precise instruments and methods have been produced to measure the Earth's gravity from space, air and Earth's surface. Such advancements improve our knowledge about the physics of our planet. To reach this goal theories and methods need to be modernised and revised. Different satellite, airborne, shipborne and terrestrial gravimetry missions aim to determine the Earth's gravity field and its temporal variations reliably and precisely. In geodesy, the main purpose is to determine the physical shape of the Earth or the geoid and define height systems. In geophysics, understanding the Earth's interior and near surface processes is the main objective. The Earth's gravity field and its temporal changes, in one way or another, reflect information about such processes. As gravity captures different processes and interior structures, its interpretation depends on our assumptions about the underlying sources. In this Research Topic, recent developments in gravity field determination and its applications are covered; e.g. geoid determination, height systems and datum unification, determination of Moho discontinuity and density contrast between crust and upper mantle, elastic thickness of the lithosphere, post-glacial rebound, earthquakes, stress modelling and mantle convection, near surface processes related to hydrology, cryosphere, oceans, atmosphere and satellite altimetry.
We welcome experts in the subject of the Research Topic to collect high quality articles showing the state-of-the-art of theories and applications of the Earth's gravity field from the Earth's near surface to the deep interior.
The Research Topic covers all subjects related to theory and applications of the Earth's gravity field for example:
• Geoid determination;
• Height systems and vertical datum;
• Satellite, airborne, shipborne, and terrestrial gravimetry and gravity field modelling;
• Satellite altimetry;
• Gravimetric Moho and density contrast modelling, elastic thickness determination;
• GRACE/GRACE-FO time-variable gravity field modelling and applications in: modelling near surface processes related to hydrology, cryosphere, ocean and atmosphere; post-seismic and Earthquake monitoring; stress changes inside the lithosphere; post-glacial rebound as well as solid and ocean tides.
