  • Koch, Igor; Shabanloui, Akbar; Flury, Jakob; Müller, Jürgen (2017-07-30)
    In this study, two approaches for the determination of total non-gravitational accelerations acting on GRACE were investigated. To investigate two approaches, GRACE Level-1B data including accelerometer sensor data, GNSS ...

    GRACE gravity field reprocessing at IGG Bonn
  • 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 ...
  • Shabanloui, Akbar; Müller, Jürgen (2015-09-20)
    Permafrost generally and in Siberia (Russia) especially plays a key role for global hydrological mass transport, climate change and the eco-system of the Earth. In this study, surface and sub-surface mass variations in the ...
  • Dehne, Marina; Cervantes, Felipe Guzman; Sheard, Benjamin; Heinzel, Gerhard; Danzmann, Karsten (Bristol : IOP Publishing Ltd., 2009)
    The Gravity Recovery and Climate Experiment (GRACE) is one of the present missions to map the Earth's gravity field. The aim of a GRACE follow-on mission is to map the gravitational field of the Earth with higher resolution ...
  • 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 ...
  • 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 ...
  • Ren, Le; Schön, Steffen (Göttingen : Copernicus GmbH, 2018)
    The Swarm mission of the European Space Agency (ESA) offers excellent opportunities to study the ionosphere and to provide temporal gravity field information for the gap between the Gravity Recovery and Climate Experiment ...
  • Eicker, Annette; Kurtenbach, Enrico; Mayer-Gürr, Torsten; Shabanloui, Akbar; Kusche, Jürgen (2012-05-24)
    Reprocessing of CHAMP and GRACE observations for the determination of improved static and temporal gravity field models with regional refinements
  • Chen, Qiang; Poropat, Lea; Zhang, Liangjing; Dobslaw, Henryk; Weigelt, Matthias; van Dam, Tonie (Basel : MDPI AG, 2018)
    Over the 15 years of the Gravity Recovery and Climate Experiment (GRACE) mission, various data processing approaches were developed to derive time-series of global gravity fields based on sensor observations acquired from ...
  • Vishwakarma, Bramha Dutt; Devaraju, Balaji; Sneeuw, Nico (Basel : MDPI AG, 2018)
    The mass change information from the Gravity Recovery And Climate Experiment (GRACE) satellite mission is available in terms of noisy spherical harmonic coefficients truncated at a maximum degree (band-limited). Therefore, ...
