Research Area C: Gravity modeling

Research Area C: Gravity modeling

In Research Area C we will analyze and combine the novel data sets from space and ground techniques in order to derive gravity field models with unprecedented accuracy and spatial resolution. The highly accurate length measurements in space will contribute the long and medium wavelengths of the Earth’s gravity field and their temporal variations. Ground based gravimeter campaigns will provide regional information on gravity and mass variations, consistently complementing the global solutions. Networks of clocks will enable the direct determination of the gravitational potential at short time scales and at different length scales, which will stabilize resulting geoid solutions. The new class of gravity field models will serve as input for further geodetic applications in the context of the Global Geodetic Observing System (GGOS) and will be the basis for Earth system research in the geosciences.
