Logo GFZ PotsdamLogo German Research Centre of Geosiences
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.
As a partner in Geo.X, the GFZ has access to an excellent network of other geoscience institutions in Potsdam and Berlin. This largest regional concentration of geoscientific competence in Europe offers first-class cooperation and development opportunities. 
For section 1.3 Earth System Modelling (department “Geodesy”), we are offering a:

PhD position (f_m_x)

Reference Number 6995

We are searching for a PhD candidate to improve an existing numerical model of the terrestrial branch of the global water cycle to fit geodetic requirements for use in global mass variation and Earth rotation studies. In cooperation with the Space Research Centre of the Polish Academy of Sciences (Warszaw), the team at GFZ is responsible for the development of numerical models of large-scale mass transport processes in the Earth’s geophysical fluids to predict mass variations that will be subsequently converted into gravity field and Earth rotation changes. The successful candidate is expected to perform a wide range of hydrological model simulations forced with either high-resolution deterministic weather forecasts or ensemble-based seasonal predictions.

Your responsibilities:

  • Refinement of a numerical model of the global terrestrial water cycle
  • Design, execute, and evaluate numerous model simulations with different initial states and under different atmospheric forcing conditions
  • Statistical analysis of residual forecast errors arising from deficits in either the numerical model or the applied atmospheric forecasts
  • Collaborative work in a highly interdisciplinary and international team
  • Presentation of your results at international conferences and project meetings
  • Publication of your results in international scientific journals

Your qualifications:

  • M.Sc. degree in physics, meteorology, hydrology, geodesy, or a related field
  • Strong skills in scientific programming with Python and Fortran
  • Experience with numerical Earth system models will be advantageous
  • Good command of the English language

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
  • Institute day-care centre on site
  • Working at the Albert Einstein science park on the Telegrafenberg in Potsdam
  • Work place within walking distance of Potsdam main train station, or just a short ride on the shuttle bus

Start date: As soon as possible
Fixed-term: 36 months
Salary: The position is classed as salary group 13 according to “TVöD Bund (Tarifgebiet Ost)”. The salary group is determined on the basis of the Collective Wage Agreement and the respective personal qualifications.
Working hours: Part-time 75% (currently 29.25 h/week)
Place of work: Potsdam
