Organisation/Company UiT The Arctic University of Norway Department Department of Physics and Technology Research Field Physics Environmental science Mathematics Computer science Researcher Profile Recognised Researcher (R2) Positions Postdoc Positions Country Norway Application Deadline 17 Aug 2025 - 23:59 (Europe/Oslo) Type of Contract Temporary Job Status Full-time Hours Per Week 37,5 Is the job funded through the EU Research Framework Programme? Not funded by a EU programme Is the Job related to staff position within a Research Infrastructure? No

The position is a fixed term position for a duration of 3years. Appointment to the position of Postdoctoral Research Fellow is mainly intended to provide qualification for work in top academic positions. It is a prerequisite that the applicant can carry out the project over the full course of the employment period. No person may hold more than one fixed term position as a Postdoctoral Research Fellow at the same institution.

The workplace is at UiT in Tromsø. You must be able to start in the position within a reasonable time after receiving the offer.

The position's field of research

The position is funded by the European Research Council (ERC) Starting Grant: SI/3D (Summer Sea Ice in 3D ). SI/3D aims to produce a 15+ year high-accuracy record of pan-Arctic sea ice thickness without interruptions in the summer, allowing us to close the Arctic sea ice volume budget, pinpointing the mechanisms driving seasonal decay and breakup of the ice pack and the feedbacks of sea ice loss on Arctic temperatures, and to upgrade seasonal sea ice forecasts from state-of-the-art modelling systems by assimilating summer ice thickness observations.

The role of this position is to support the development of a sea ice model-data assimilation framework in WP3 of SI/3D and perform seasonal sea ice forecasting experiments. The postdoc will set up the data assimilation framework for summer sea ice thickness (SIT) observations within the FESOM2-ICEPACK modelling system, in collaboration with Dr. Frank Kauker’s group at AWI. The postdoc on WP3will spend between 6 and 12 months working at the AWIearly in the appointment, supported by funding from SI/3D, to train with the modelling system and develop the assimilation framework through PDAF. Tasks will include: preparing the assimilation framework for accepting SIT observations from radar altimetry into the multi-sea ice thickness-category FESOM2-ICEPACK model, testing the assimilation of data at different processing levels (ITDs, freeboard, and different snow depth products), and performingseasonal sea ice edge forecasts.

The postdoc will work directly with other members of the SI/3D team, including the PI, another Postdoctoral Researcher, and a PhD Student. The candidate will further join a growing team of researchers studying polar sea ice within the Earth Observation Group at the UiT Department of Science and Technology.

The role of the position

The position will be 100% devoted to research and development tasks. The candidate will be required to take on a leadership role within the associated ERC project, including collaboration with project partners, participation in project meetings, communication & dissemination at conferences, and contribution to reporting.

The candidate will participate in research towards some of the following project work; however, there is flexibility for the candidate to propose and direct their own research:

• Set up the data assimilation framework for summer sea ice freeboard & thickness observations within FESOM2-ICEPACK, in collaboration with Dr. Frank Kauker’s group at AWI
• Spend between 6 and 12 months working at the AWI, supported by funding from SI/3D, to train with the modelling system and develop the assimilation framework through the PDAF
• Work with the PI and other Postdoc in SI/3D to improve the quality and suitability of remotely-sensed sea ice products for model-data assimilation
• Test the assimilation of ITDs, freeboard, and different snow depth products versus simply using the mean SIT
• Intercompare seasonal forecasts for the sea ice edge location based on the assimilation of SIT observations into the different ensemble prediction systems, including those at AWI and GFDL
• Test the utility of regional sea ice forecasts for Norwegian Ice Service operations in the Barents Sea and around Svalbard, to identify for instance how early atypical ice conditions can be predicted with the assimilation of near real-time satellite SIT observations

About the workplace

UiT The Arctic University of Norway, with its main campus located in Tromsø, is the northernmost university in the world. Its focus on climate and the environment is clearly dictated by its geographical location at the edge of the Arctic. The main task of the Faculty of Science and Technology is to conduct research and teaching at a high national and international level. Prioritized research areas include energy, climate, environment, maritime, marine, nano-, space-, and information technology, addressing both general topics and topics relevant to the High North.

The Department of Physics and Technology consists of six research groups: Earth Observation, Renewable Energy, Machine Learning, Complex Systems Modelling, Space Physics, and Ultrasound, Microwaves, and Optics. The department provides education at the Bachelor, Master, and PhD levels.

• a Norwegian doctoral degree within a field relevant for the research theme of the position (i.e., computer science, physics, mathematics, or environmental science), or a corresponding foreign doctoral degree recognised as equivalent to a Norwegian doctoral degree.
• fluency in English and good communcation skills. Nordic applicants can document their capabilities by attaching their high school diploma

Qualification with a PhD is required before commencement in the position. If you’re at the final stages of your PhD, you may still apply if you have submitted your PhD thesis for doctoral degree evaluation within the application deadline. You must submit the thesis with your application. You must have completed your defense before the start-up date of the position.

We are looking for a strongly motivated person, who has:

• an excellent academic record and potential, with analytical and problem-solving skills
• a strong background in applied mathematics
• a suitable candidate should have experience working with climate models, preferably on model development and/or data assimilation
• a strong background in computer science, and good programming skills, to suit the Department of Physics at UiT
