FU Berlin Researcher / Scientific Programmer (postdoc) (m/f/d) in Hamburg at German Climate Computing Center (DKRZ)

Major Project ClimXtreme - Sub Project CoSoX
Climate extremes can be identified in different observational data sets as well as in the results of model simulations. Such data sets include station networks, gridded observations, different reanalyses, weather forecasting products, climate modeling results for past, present and future based on global and regional models, to name a few. As extremes can be found on different time scales, and a specific suite of archived meteorological and other parameters is necessary for their understanding, the choice of suitable data sets is a most important step in their analysis. Research on extremes can also benefit from the fact that scientists can learn from each other’s results. This can be particularly strong if a close relation of specific topics supports joint evaluation steps and procedures, and/or the same data sets.
ClimXtreme Module D and in particular its sub-project CoSoX will foster research and collaboration between scientists by providing data and information. It will exploit synergies with related activities like the existing BMBF funded MiKlip ( and CMIP6-DICAD ( projects. A central data-access and data-evaluation system will be installed for the program – the ClimXtreme Central Evaluation System (X-CES). The system shall be based on the FUB evaluation system framework, a derivative of the Central Evaluation System (CES) developed and published in the MiKlip program ( Standardized evaluation tools and data access to relevant data sets will be provided. Part of the service is an easy identification of data sets suitable for specific evaluations, and subsequent data access. Second, the system shall provide a repository of tools or so-called plugins, serving the scientists contributing to the program. The evaluation tools shall include basic procedures needed for the identification,
statistical assessment and evaluation of extreme events and the larger scale conditions under which they occur.

The position will be located at the DKRZ in Hamburg within the research group of Dr. Christopher Kadow - ‘Climate Informatics and Technologies’. Employment by Freie Universität Berlin (FUB).

Job description:
• Support of ClimXtreme on software related issues. Coordination with DKRZ HPC team. Coordination of Module-D activities with the steering committee.
• Development of the evaluation strategy and organisation of the upcoming data and software streams in ClimXtreme. Setup of the software infrastructure at the DKRZ. Workshop organization, support (travel) for users and developers.
• Establish the X-CES including data management of input streams and software management of different plugins of ClimXtreme project partners. Coordinate the developments of the 3 Modules (Process, Statistics, and Impacts) in terms of scientific software and data. Visit project partners.
• Coordination of the data and plugin combinations for ClimXtreme, framework advancement with external data sources (e.g. ESGF, Copernicus C3S), interface development for common results of ClimXtreme and potential impact modelers. Administration, bug-fixing, adjustments to HPC architectures.

PhD in Meteorology, within Natural Sciences, Computer Science, or similar fields.

Job experience:
Experience in the field of climate model data (data standards), evaluation of climate extremes,
