  • Earth’s Time-Variable Gravity from GRACE Follow-On K-Band Range-Rates and Pseudo-Observed Orbits 
    Koch, Igor; Duwe, Mathias; Flury, Jakob; Shabanloui, Akbar (Basel : MDPI, 2021)
    During its science phase from 2002–2017, the low-low satellite-to-satellite tracking mission Gravity Field Recovery And Climate Experiment (GRACE) provided an insight into Earth’s time-variable gravity (TVG). The unprecedented ...
  • GRACE and GRACE-FO processing at IfE/LUH 
    Koch, Igor; Flury, Jakob; Duwe, Mathias; Shabanloui, Akbar (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    Updates on gravity field recovery from GRACE and GRACE Follow-On data at IfE/LUH.
  • GRACE-FO processing at IfE/LUH 
    Koch, Igor; Duwe, Mathias; Flury, Jakob; Shabanloui, Akbar (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    Processing strategy of the LUH-GRACE-FO-2020 monthly gravity field time series is presented. The spectral noise, spatial noise and signal content of the time series (2018-06 - 2020-08) is evaluated.
  • Residual ocean tide signal in GRACE(-FO) range-rate post-fit residuals 
    Koch, Igor; Duwe, Mathias; Flury, Jakob (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023-11-02)
    Ocean tide model imperfections are one of the major uncertainty factors in gravity field recovery. Unmodeled signal can alias into level-2 gravity field products and be interpreted as real signal, e.g. as ice mass loss. ...
  • Signals of Geophysical Nature in GRACE and GRACE-FO Post-Fit Range-Rate Residuals 
    Koch, Igor; Duwe, Mathias; Flury, Jakob; Fletling, Nina (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    Post-fit residuals of satellite-to-satellite tracking measurements of the GRACE and GRACE-FO missions obtained after a common estimation of orbit and gravity field parameters should ideally contain measurement noise with ...
  • Spectral analysis of residual GRACE and GRACE-FO range accelerations 
    Koch, Igor; Duwe, Mathias; Flury, Jakob (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    GRACE and GRACE-FO K-band range-rate post-fit residuals obtained after a common estimation of monthly gravity field coefficients and ancillary satellite parameters represent a complex superposition of different effects. ...
