In the coming decades, climate and land use change will have a significant impact on the performance of terrestrial ecosystems, posing major challenges to our society. At the Institute of Bio- and Geosciences – Agrosphere (IBG-3) – we develop approaches to ensure the performance of ecosystem services (food, feed, fiber, energy) based on an improved understanding of hydrological and bio-geochemical processes in terrestrial systems. A combination of experiments, modelling and innovative observation technologies is used to bridge the gap between model, process and management scale. We translate our research findings into management options that can be used by political organizations and decision-makers to address these societal challenges. Further information on our mission can be found here.

We are looking to recruit a

Postdoc - Fully Coupled Regional Reanalysis

Your Job:

As a Postdoc at the IBG-3 you contribute to the DFG-funded project DETECT (Regional Climate Change: Disentangling the Role of Land Use and Water Management). DETECT is a research network of hydrologists, meteorologists, land use modellers, geodesists, data assimilation and remote sensing specialists, data scientists, agricultural economists, and social scientists from the Faculties of Agriculture and Mathematics and Natural Sciences of the Rheinische Friedrich Wilhelms University Bonn, the Universities of Cologne and Göttingen, the Forschungszentrum Jülich and the Deutscher Wetterdienst. Projects within DETECT investigate how land use and water management lead to persistent modifications in the coupled water and energy cycles of land and atmosphere (“drying” and “wetting”); and thus disentangle the role of these drivers of regional climate change from radiative forcing.

In this position, you will perform simulations and data assimilation experiments with a coupled land surface and subsurface model for the European continent. You will make use of existing implementation of data assimilation capacity, which needs to be tuned for applications at the continental scale. You will develop a reanalysis with the land surface-subsurface model over Europe assimilating different types of land surface and subsurface observations, and evaluate the accuracy of the reanalysis with independent verification data. You will work together with atmospheric scientists from the University of Bonn and the German Weather Service towards a fully coupled data assimilation scheme which includes atmosphere, land surface and subsurface. This fully coupled framework will be tested for short selected time periods at the end of the project.

Your main tasks will include:

  • Further development of a weakly coupled data assimilation scheme for the land surface and subsurface at the scale of Europe
  • Production of a weakly coupled reanalysis based on assimilation of land surface and subsurface variables
  • Evaluation of the weakly coupled reanalysis with independent data
  • Development of a strongly coupled data assimilation scheme for atmosphere, land surface and subsurface together with project partners
  • Maintaining contact and cooperate with project partners
  • Publishing results in international peer reviewed journals
  • Participating in project meetings and national and international conferences

Your Profile:

  • M.Sc. and PhD in atmospheric sciences, geosciences, simulation sciences, applied mathematics, statistics, informatics. or a related field
  • Good experience in terrestrial systems modelling (e.g., atmosphere, land surface, groundwater, integrated hydrology) or very good experience in modelling and high interest in terrestrial systems
  • Strong background in data analysis and statistics, including data assimilation or inverse modelling
  • Good programming skills (e.g., Python, Fortran, R, C++)
  • Experience with Linux-based systems and high-performance computing
  • Scientific track record (relevant ISI-listed first author publications)
  • Ability to work independently as well as collaboratively in an interdisciplinary team
  • Very good communication and organizational skills
  • Fluent command of English language

Our Offer:

We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change! We support you in your work with:

  • Participation in national and international conferences and workshops
  • Further development of own scientific profile through a strong international network
  • Cooperation in a highly motivated, international and interdisciplinary team
  • Extensive internal and external training opportunities
  • Exciting working environment on an attractive research campus, conveniently located in the Cologne-Düsseldorf-Aachen triangle of cities
  • Flexible work time arrangements and a wide range of options for reconciling work and family life
  • Full-time position with the option of slightly reduced working hours and 30 days of annual leave
  • A position starting as soon as possible, limited for three years with possible longer-term prospects
  • Salary and social benefits in conformity with the provisions of the Collective Agreement for the Public Service (TVöD)

We welcome applications from people with diverse backgrounds, e.g. in terms of age, gender, disability, sexual orientation / identity, and social, ethnic and religious origin. A diverse and inclusive working environment with equal opportunities in which everyone can realize their potential is important to us.

The job will be advertised until the position has been successfully filled. You should therefore submit your application as soon as possible. We look forward to receiving your application via our Online Recruitment System!
