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 1.1 Space Geodetic Techniques (department “Geodesy”), we invite applications for a:

Research Scientist (f_m_x) - GNSS Reflectometry

Reference Number 9124

The focus of GNSS Reflectometry lies in the usage of signals from navigation satellites for remote sensing of the Earth’s atmosphere and surface with ground and satellite based techniques. Main observation data are from global and regional GNSS ground networks, dedicated ground and flight experiments and from several Low Earth Orbiting (LEO) satellites. The resulting data products, e.g., atmospheric water vapor, wind velocity and Earth’s surface properties, as soil moisture, are used in several fields of Earth System Science. To support our GNSS Remote Sensing team as soon as possible, we look for a new colleague. The position combines recent and innovative research tasks under operational aspects within an international research environment with interdisciplinary cooperation partners. 

Your responsibilities:

  • Development of GNSS reflectometry techniques for meteorological applications, such as measurements of wind velocity/direction and potentially precipitation over oceans, and vegetation, soil moisture, and snow under consideration of operational aspects and the integration of signals of all navigation satellite systems including GPS, Galileo, GLONASS and BeiDou
  • Validation of the GNSS reflectometry based data with other independent techniques, such as satellite radars and in-situ measurements to improve their quality and characterize the errors, accuracy and precision 
  • Active support of the cooperation with partner institutions for the operational application of GNSS reflectometry based data in atmospheric research, weather forecast and climate studies

Your qualifications:

  • Master´s degree or equivalent and a PhD degree in Geodesy, Meteorology, Physics, Geophysics or similar preferably with a thesis topic in GNSS Reflectometry
  • Strong background and publication record in the development and application of GNSS reflectometry techniques, operational GNSS data processing and handling of ground or satellite based GNSS remote sensing data
  • Experience in the derivation of atmospheric parameters from GNSS reflectometry observations with preferably demonstrated ability to develop novel meteorological applications
  • Preferably experience with machine learning for the processing of GNSS reflectometry data 
  • Experience with the development of scientific software packages, e.g. in Python and/or Matlab, good knowledge of UNIX/Linux 
  • Demonstrated capability in proposal writing and securing third party funding will be an advantage

Special Skills:  

  • Very good English skills
  • Adaptability to a multi-disciplinary and international team with the appropriate communicative competence 
  • High motivation and self-dependency 
  • Creativity for novelty and original research

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 siteWorking 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: 3 years
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: Full-time (currently 39 h/week). The position is, in principle, suitable for part-time employment.
Place of work: Potsdam
