Postdoctoral researcher (f/m/d): Urban-scale air quality modeling using WRF-Chem with urban canopy model

The Center for Advanced Systems Understanding (CASUS) is a German-Polish research center for data-intensive digital systems research. We combine innovative methods from mathematics, theoretical systems research, simulations, data science, and computer science to provide solutions for a range of disciplines – materials science under ambient and extreme conditions, earth system research, systems biology, and autonomous vehicles.

CASUS was jointly founded in August 2019 by the Helmholtz-Zentrum Dresden-Rossendorf, the Helmholtz Centre for Environmental Research, the Max Planck Institute of Molecular Cell Biology and Genetics, the Technical University of Dresden and the University of Wroclaw. CASUS is located in the heart of Görlitz at the border between Germany and Poland. The CASUS start-up phase is hosted by the Helmholtz-Zentrum Dresden-Rossendorf and is financed by the Federal Ministry of Education and Research and the Saxon State Ministry of Science and Art.

The Department Earth Systems Research is looking for a Postdoctoral researcher (f/m/d) interested in urbanscale air quality modeling using WRF-Chem with urban canopy model. The position can begin immediately, and the contract will be limited to 31 March 2022.

Scope of your Job

The candidate (f/m/d) will contribute to a project to build a robust and reliable high-resolution air quality forecasting system for a city. The forecasting system is being designed as a decision-making tool for stakeholders, and to increase an awareness of urban air quality issues for city residents. Under this project, the researcher will use a 3-D air quality model, i.e., WRF-Chem, for high-resolution simulation of air quality over a European city with heavy traffic emissions.


  • Establish WRF-Chem in the CASUS HPC environment
  • Configure WRF-Chem with urban canopy model for reliable urban air quality simulations
  • Create new land use map for a city using satellite data using GIS program
  • Evaluate the model against observational datasets {both remote sensing and in-situ)
  • Build traffic-related emissions from the traffic observation datasets
  • Publish research results in peer-reviewed scientific or technical journals and present results at external conferences seminars and/or technical meetings
  • Collaborate with others in a multidisciplinary team environment to accomplish research goals
  • Pursue independent (but complementary) research interests and interact with a broad spectrum of scientists internally and externally


  • PhD degree in in atmospheric science; mechanical, civil or environmental engineering, or a closely related field
  • Experience with urban to regional scale meteorological and atmospheric chemistry and transport models and their application to air quality (preferably WRF-Chem and urban canopy models)
  • Experience with traffic emission modeling, GIS programs and model bias correction techniques
  • Solid understanding on atmospheric boundary layer structures and transport/deposition of air pollutants in a city
  • Excellent programming skills in languages such as Fortran, Python and Shell-script
  • Strong motivation to work in a collaborative environment
  • Excellent communication skills in English and in a professional context (presentation of research results at scientific meetings, colloquial discussions, writing of manuscripts)

We offer:

  • A vibrant research community in an open, diverse, and international work environment

  • Scientific excellence and high quality of training, coaching, and mentoring programs according to the Helmholtz Doctoral Guidelines

  • Broad national and international science networks

  • Salary according to the German Collective Wage Agreement for the Civil Service (TVöD)

  • Comprehensive benefits package (30 vacation days per year, company pension plan (VBL), flexible working hours, in-house health management, relocation assistance).

Please submit your application (including a one-page cover letter, CV, academic degrees, transcripts, etc.) online on Online-application-system.
