PostDoc Sea Ice Forecast Research

The Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) is a member of the Helmholtz Association (HGF) and funded by federal and state government. AWI focuses on polar and marine research in a variety of disciplines such as biology, oceanography, geology, geochemistry and geophysics thus allowing multidisciplinary approaches to scientific goals.

PostDoc "Sea Ice Forecast Research" (m/f/d)

Background

This position is part of the BMBF junior research group “Seamless Sea Ice Prediction” in the Climate Dynamics section at the Alfred Wegener Institute. The junior research group deals with various aspects of sea ice prediction including model development, initial value determination through data assimilation, and forecast verification methods. To this end, the group primarily develops and uses a sea ice forecast system based on a global coupled climate model (AWI-CM) in combination with ensemble data assimilation. You should primarily contribute to the further development of the prediction system and the exploration of the influence of various observation data on the quality of the prediction. The research work will be carried out in close cooperation with the data assimilation group of Dr. Lars Nerger.

Tasks

• First, you should supplement the initial value determination of the sea ice prediction system, which so far has only assimilated ocean and sea ice observation data, with relaxation of the atmospheric state using reanalysis data. The interplay between ensemble assimilation in the ocean / sea ice and relaxation in the atmosphere will be of particular interest. The direct initialization of the atmosphere is expected on the one hand to lead to significant improvements in the short-term range of the forecasts, but on the other hand to contribute also to a better initialization of the ocean / sea ice state.
• Second, idealized "perfect twin" or "imperfect twin" experiments are to be carried out with the prediction system, in which synthetic observations from a free-running simulation (i.e. without assimilation and / or relaxation) are used. This way it shall be possible to work out statements about observing system requirements (type, spatial-temporal resolution, observation errors) and the influence of systematic model errors.

Requirements

• PhD in meteorology, oceanography, climate sciences, physics, mathematics, or similar.
• proven programming skills (especially Fortran and Python),
• fluent English skills,
• experience with complex climate models (application and data analysis),
• a strong publication record
• experience with data assimilation is advantageous
• the skills to develop your own research questions and to tackle both scientific and technical challenges individually while working well as part of a team.
