The Helmholtz Centre Potsdam – GFZ German Research Centre for Geosciences is the national centre for geosphere research. As a member of the Helmholtz Association of German Research Centres we are part of the largest scientific organization in Germany. With approximately 1,500 employees our key mission is to secure a profound understanding of the systems and processes of solid Earth, to develop strategies and options for action in addressing global change and its impacts on a regional level, to understand natural hazards and to minimize associated risks, to ensure the sustainable provision of energy and raw materials for a high-tech society and to evaluate the influence of human activity on system Earth.
For section 1.2 Global Geomonitoring and Gravity Field we are looking for a:

Scientist (f_m_x) GRACE - FO

Reference Number 7836

The Earth´s gravity field including its temporal variations is a key parameter for understanding our system Earth. Dedicated gravity satellite missions such as GFZ-1, CHAMP, GRACE, GOCE and GRACE-FO, to a large extent developed, operated and analysed by Section 1.2 “Global Geomonitoring and Gravity Field”, enable to study mass distribution and mass transport on various spatial and temporal scales. Currently, Section 1.2 is operating the GRACE-FO Science Data System and preparing, together with DLR/NASA, a GRACE-FO successor mission (planned launch in 2028) as well as, together with ESA, a NGGM/MAGIC double pair constellation (anticipated launch in 2031), in order to guarantee data continuity and to improve temporal and spatial resolution of mass transport products. Furthermore, together with DLR/Airbus the benefit of a future Quantum Gravity Gradiometer (QGG) satellite mission will be analyzed till the end of 2024. 

Your responsibilities:

  • Perform full-scale simulations with the software EPOS, developed inhouse at Section 1.2, to investigate the performance of various single pair, double pair and QGG mission scenarios (orbits, instrument characteristics, background modeling, etc.)
  • Calculate monthly GRACE-FO gravity field solutions with EPOS based on Laser Ranging Interferometer data to be used for static gravity field determination
  • Investigate the potential benefit of range and/or range-acceleration low-low satellite-to satellite tracking (ll-SST) data compared to standard range-rate ll-SST data within full-scale simulations and by application to GRACE/GRACE-FO real data
  • Documentation and presentation of results at project meetings and international conferences

Your qualifications:

  • Master`s degree (or equivalent) in geodesy, mathematics or physics (PhD required)
  • Proven knowledge (by PhD thesis and peer reviewed papers) to derive the time-variable gravity field from simulated and real gravity satellite mission data
  • Profound knowledge of adjustment theory and signal processing
  • Very good experience in processing of large datasets with a huge number of observations and parameters to be estimated
  • Very good programming skills (shell scripting, Fortran, MATLAB/Octave) and Linux knowledge
  • Very good English language skills
  • Experience working in an interdisciplinary and international research and industry environment with appropriate communications skills

What we offer:

  • Ambitious and varied tasks in a dynamic and international research environment
  • State-of-the-art equipment
  • Public service benefits
  • Extensive training opportunities
  • Professional career advice offered by our in-house Career-Centre
  • Flexible working hours and conditions
  • Support with finding a good work-life balance offered by benefit@work
  • Attractive location in Oberpfaffenhofen in proximity to the DLR

Start date: 1st November 2023
Fixed-term: 18 months
Salary: The position is classed as salary group 13 according to “TVöD Bund (Tarifgebiet West)”. The salary group is determined on the basis of the Collective Wage Agreement and the respective personal qualifications.
Working hours: Full-time (currently 39 h/week); The position is generally suitable for part-time work.
Place of work: Oberpfaffenhofen
