At the Leibniz Institute of Atmospheric Physics (IAP), a full-time position (40 hours / week) in the Department 鈥淢odelling of Atmospheric Processes鈥� is available as

Postdoctoral Scientist 鈥淐oupled Ionosphere-thermosphere Modelling鈥� (f/m/div)

The position is initially offered for three years with a start date as soon as possible. The employment is according to the Collective Agreement for the Public Service of the Federal States (E 13 TV-L).

The Leibniz Institute of Atmospheric Physics advances the scientific knowledge of the coupling between space and atmosphere by developing and exploiting expertise in atmospheric physics, instrumentation, analysis, and modeling to serve emerging societal needs. The department Modelling of Atmospheric Processes develops the upper-atmosphere version of the general circulation model ICON, i.e. UA-ICON, a state-of-the-art high-resolution model of the neutral atmosphere with a model top at 250 km height. UA-ICON includes a deep-atmosphere dynamical core and supplementary parametrizations for relevant physical processes, such as molecular diffusion, ion-drag and Joule heating, frictional heating, and radiation.

The Thermosphere Ionosphere Electrodynamics General Circulation Model (TIE-GCM) is a global 3D numerical model that simulates the coupled ionosphere-thermosphere system from 鈭�97 to 鈭�600 km height. It self-consistently solves the fully coupled nonlinear, hydrodynamic, thermodynamic, and continuity equations of the neutral gas, the ion and electron energy equations, the O+ continuity equation and ion chemistry, and the neutral wind dynamo. The lower boundary at the mesopause allows conducting controlled experiments to delineate the effects of lower-atmospheric forcing.

To achieve this, the successful candidate will set up the TIE-GCM to be driven with output of the neutral atmosphere dynamics and chemistry of UA-ICON. A requirement will be to install TIE-GCM at the supercomputer of the German Climate Computing Centre, where UA-ICON is running. Scientific studies focusing on the ionospheric electric current systems including comparisons with observations will be conducted in close collaboration with the working group Satellite Data Analysis.

Your qualifications / experience:

• a PhD in physics, geoscience, or a related field
• proven expertise in numerical modeling using supercomputing clusters
• excellent knowledge of atmospheric physics
• proficiency in English as a working language
• a concept for best practices regarding code documentation
• strong communication skills

What we offer:

• an attractive working place near the Baltic Sea
• modern computational and experimental facilities
• engagement in an international work environment
• participation in the company pension scheme (VBL)
• employment relationship in accordance with the provisions of the Collective Agreement for the Public Service of the Federal States (TV-L)
• flexible working hours and mobile working within the framework of the applicable regulations
• Pedelec bike leasing options are supported by the institute

Who we are:
Our mission is to advance the scientific knowledge of the mesosphere and lower thermosphere by developing and exploiting expertise in atmospheric physics, instrumentation, analysis, and modeling to serve emerging societal needs 鈥� such as questions regarding atmospheric change. At the regional level, we maintain a close partnership with the University of Rostock and play an integral role in the teaching program of its Institute of Physics. Nationally and internationally, we are well connected within the research community. As member of the Leibniz Association, we are committed to being a modern, innovative employer that values family friendliness, equal opportunities, and flexibility.
