Testo originale dell'annuncio (in inglese)

Work group: Institute of Coastal Environmental Chemistry Area of research: Scientific / postdoctoral posts Starting date: 11.08.2026 Job description: Postdoctoral Researcher - Ultrafine particles around airports Job ID: 1045 Location: Geesthacht near Hamburg/Germany Project start November 15, 2026 until June 30, 2028. Application deadline: August 30, 2026 Airports are large sources of ultrafine particles. These particles are transported in the atmosphere, leading to human exposure at distances up to 10-20 km from the source. In the SOURCE-FFR impact study, we investigate the granular distribution of ultrafine particles around the airport of Frankfurt and look for possible long-term health effects. We run atmospheric chemistry transport models to simulate the spatial distribution of ultrafine particles and use geostatistical interpolation tools to produce very high resolution concentration data. You will work with atmospheric urban-scale chemistry transport models, meteorological and geostatistical approaches for spatial downscaling of atmospheric concentration data. You will join an interdisciplinary project team at the interface of environmental modelling and data science. At Hereon, the research group combines: - long-standing expertise in air quality modelling - with growing activities in data-driven methods You will work closely with: - Dr. Martin Ramacher (machine learning for environmental applications) - Dr. Matthias Karl (urban air quality modelling and emissions) and collaborate within a project consortium with expertise in: - Epidemiology and human health data We value a collaborative, inclusive, and respectful working environment and actively encourage diverse perspectives in research. Equal opportunity is an important part of our personnel policy. We would therefore strongly encourage qualified women to apply for the position. In principle, the full time position (39 h/week) is also sharable. The project duration is planned to June 2028 with option of extension. Your tasks You will play a key role in the methodological development of geostatistical interpolation tools for atmospheric concentrations of ultrafine particles. Your focus will be on: - Running and evaluating atmospheric chemistry transport models - Interpreting meteorological data - designing and implementing the geostatistical interpolation methods - You will apply chemistry transport model systems and calculate ultrafine particle concentrations around Frankfurt airport - You will analyse meteorological data and evaluate atmospheric model results - You will develop and apply methods for geostatistical interpolation of ultrafine particle concentration data - You will run models on HPC systems - You will publish your work and contribute to open-source releases Your profile - PhD in Meteorology, Physics, Computer Science, Environmental Sciences, or a related field - Experience with atmospheric models and geostatistical interpolation methods - Strong programming skills in R, Python or similar languages - Intrinsic motivation to work on complex, real-world problems with societal relevance Nice to have: - Experience with spatio-temporal or geospatial data - Experience with HPC Our offer - an exciting and varied job in a research center with around 1,000 employees from more than 60 nations - International Welcome Office with guest accommodation - 6 weeks holiday per year; company holidays between Christmas and New Year's Day - social benefits according to the collective agreement of the public service and remuneration up to pay group 13 (according to EntgO Bund) - very well work-life balance; options for mobile and flexible work - a well-connected research campus (public transport) and best networking opportunities, subsidy for the Deutschlandticket if certain conditions are met (job ticket), charging facilities for electric vehicles - individual opportunities for further training - an excellent technical infrastructure and modern workplace equipment - family-
