Job vacancy:
Postdoc (Sea-ice data assimilation and prediction)

Code: 149/D/Kli
Faculty: Science
Job type: Full time
Location: Bremerhaven

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.

The Section “Climate Dynamics” invites applications for a position as

Postdoc (Sea-ice data assimilation and prediction).

This position is part of the new Junior Research Group „Seamless Sea Ice
Prediction“ (SSIP, 2017-2022), which is funded through the BMBF
„Nachwuchsgruppen Globaler Wandel 4+1“ Programme and led by Dr. Helge

Advanced sea-ice prediction capacity is urgently needed to meet a
growing socio-economic demand, driven in particular by an increasing
accessibility of the Arctic in the course of cli- mate change.
Operational sea-ice prediction systems have been developed recently, but
research on potential predictability suggests that operational sea-ice
predictions could be much more skillful than they currently are. One
impediment that hampers progress is a gap between short-term (days) and
longer-term (months and longer) sea-ice prediction systems. SSIP works
towards advancing sea-ice prediction capacity on timescales from hours
to years and beyond. To achieve this, SSIP develops and conducts
research with a seamless sea-ice prediction system based on the recently
developed AWI Climate Model. The unstructured grid of the ocean/sea-ice
component of this model (FESOM2; allows
to use high resolution in the polar regions (plus other key regions) in
a global setup, enabling a seamless application of the prediction system
on a wide range of timescales. The group applies state-of-the-art
techniques to initialise the prediction model using remote-sensing and
in-situ observations; it optimises and further develops the sea-ice
component of the prediction model; and it applies the prediction system
to address research questions related to sea-ice predictability,
verification, and the impact of different observations on sea-ice

You will join a team that adds an Ensemble Kalman Filter based on PDAF
(<>) to the AWI Climate Model. The focus of the work is
on sea-ice data assimilation, with tasks ranging from the selection,
retrieval, and preparation of suitable observational data to the tuning
and further development of the forecast system. You will investigate
aspects of partially coupled (sea-ice/ocean) and fully coupled
(sea-ice/ocean/atmosphere) data assimilation, working with idealised
setups where virtual observations are obtained from a reference
simulation as well as „real-world“ setups. Jointly with other members of
the SSIP Group, you will assess the impact of different observations,
work out recommendations for the design of the polar observing system,
and disseminate results through scientific publications.

You must have a PhD in one of the following fields: meteorology,
oceanography, climate sciences, physics or mathematics. Demonstrated
programming skills (in particular FORTRAN), fluency in English,
experience with running and analyzing complex climate models, a strong
publication record, and in particular experience with data assimilation
are all distinct advantages. Capabilities to develop your own research
questions and to tackle scientific as well as technical challenges
individually while working as part of a team are desirable.

This is a 4-year position starting as soon as possible. The salary will
be paid in accordance with the German Tarifvertrag des öffentlichen
Dienstes (TVöD Bund), up to salary level 13. The place of employment
will be in Bremerhaven.

We offer you a multi-disciplinary, international, and fascinating
professional environment with flexible working hours, state-of-the-art
research equipment, and a first-rate infrastructure. AWI aims to
increase the number of women in the scientific staff and therefore
encourages women to apply. Disabled applicants will be given preference
when equal qualifications are present. The AWI fosters the compatibility
of work and family through various means. Because of our engagement in
the area of work-life compatibility we have been awarded the certificate
“Career and Family”.

Please forward your applications with the standard documentation (cover
letter with motivation, CV and two references / letters of
recommendation) by 10th November 2017 referencing code 149/D/Kli to:
Alfred-Wegener- Institut für Polar- und Meeresforschung,
