  • 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 monthly solutions using the GRACE-SIGMA software 
    Koch, Igor; Flury, Jakob; Shabanloui, Akbar (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    In this contribution we present gravity field monthly solutions from GRACE Follow-On (GRACE-FO) Level-1B sensor data. The monthly solutions are computed with the GRACE-SIGMA software developed at the Institute of Geodesy, ...
  • 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.
  • GRACETOOLS - GRACE gravity field recovery tools 
    Darbeheshti, Neda; Wöske, Florian; Weigelt, Matthias; McCullough, Christopher; Wu, Hu (Basel : MDPI AG, 2018)
    This paper introduces GRACETOOLS, the first open source gravity field recovery tool using GRACE type satellite observations. Our aim is to initiate an open source GRACE data analysis platform, where the existing algorithms ...
  • Impact of groundtrack pattern of a single pair mission on the gravity recovery quality 
    Iran-Pour, Siavash; Weigelt, Matthias; Amiri-Simkooei, Alireza; Sneeuw, Nico (Basel : MDPI AG, 2018)
    For future gravity satellite missions, aliasing of high frequency geophysical signals into the lower frequencies is one of the most challenging obstacles to recovering true gravity signals, i.e., to recover the truth. ...
  • Influence of accelerometer parametrizations on GRACE post-fit residuals 
    Koch, Igor; Shabanloui, Akbar; Flury, Jakob (München : European Geosciences Union, 2019-04-07)
    Accelerometers onboard of satellites can be regarded as a key improvement in gravity field recovery. These instruments are located in the center of mass of the satellite and are precisely measuring non-gravitational forces ...
  • LUH-GRACE2018 
    Koch, Igor; Flury, Jakob; Naeimi, Majid; Shabanloui, Akbar (Berlin ; Heidelberg : Springer, 2020)
    In this contribution, we present the LUH-GRACE2018 time series of monthly gravity field solutions covering the period January 2003–March 2016. The solutions are obtained from GRACE K-Band Range Rate (KBRR) measurements as ...
  • LUH-GRACE2018: A new time series of monthly gravity field solutions from GRACE 
    Koch, Igor; Naeimi, Majid; Flury, Jakob; Shabanloui, Akbar (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018-10-09)
    In this contribution, we present a new time series of monthly gravity field solutions mainly obtained from GRACE K band range rate (KBRR) measurements. Our monthly solutions are computed using the in-house developed ...
  • LUH-GRACE2018: Neue Zeitreihe monatlicher GRACE-Lösungen 
    Koch, Igor; Naeimi, Majid; Flury, Jakob (2018-10-16)
    Dieser Beitrag beschäftigt sich mit einer neuen Zeitreihe monatlicher Schwerefeldlösungen aus GRACE KBRR-Beobachtungen. Diese monatlichen Lösungen wurden mittels eigener GRACE-SIGMA Software in zwei Prozessierunsschritten ...
  • 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. ...
