CRC 1464 (TerraQ)

  • Gravity Field Solution by Exploiting the Full Potential of GRACE Follow-On (SFB 1464, C04)
    The overall aim of this project is to take maximum advantage of the data of the GRACE and GRACE-FO missions and derive the best possible time-variable gravity field with monthly and daily solution. We anticipate an increased spatial resolution and a reduction of systematic errors due to improved background modelling and co-estimation of geophysical and instrumental parameters.

  • Modelling of Mass Variations Down to Small Scales by Quantum Sensor Fusion (CRC 1464, C05)
    Observing the temporal variations of the Earth gravity field by satellite gravimetry, terrestrial gravimetry or loading time series via GNSS gives insight into the temporal and spatial changes in the distribution of water on various scales. The overall aim of this project is to develop models of regional time-variable gravity (or, equivalently, of total water storage variations) at uttermost high spatial and temporal resolution by the consistent integration of the various geodetic sensors. The project thus tackles one of the currently most pressing challenges in geodesy and its dependent geophysical applications.
