Postdoctoral Research Assistant on data assimilation
University of Reading
Nonlinear Processes in Geosciences (NP)
Ocean Sciences (OS)
We are seeking for an enthusiastic, self-motivated and independent Postdoctoral Research Assistant to work within the international project “Scale-aware sea-ice project – SASIP” (https://sasip-climate.github.io/) funded and supported by the Schmidt Futures foundation (https://schmidtfutures.com/). SASIP aims at developing a truly innovative, scale-aware continuum sea ice model for climate research; one that faithfully represents sea ice dynamics and thermodynamics and that is physically sound, data-adaptive, highly parallelized and computationally efficient.
The postholder will work on Data Assimilation strategies adapted to models using a discontinuous Galerkin numerical method. The goal is to design a DA scheme that works in concert with the “shock-capturing” of a discontinuous Galerkin numerical model. In particular the postholder will investigate novel ensemble-DA methods that act directly on the local Galerkin coefficients on each element of the mesh, thus obviating the need to map back from the data-informed global analysis to the local elements. She/he may also consider incorporating ML within the DA workflow to enable data-driven decision on the form of the analysis updates.
This recruitment is one of the two concomitantly happening at University of Reading within SASIP, the other being for a PDRA working on DA for parameter estimation: the two PDRAs will interact very closely and constitute the core of SAPIP working group at University of Reading. Please see separate advert for the other position.
The postholder will be based at the Dept of Meteorology, University of Reading and will be part of the Data Assimilation Research Centre (DARC, https://research.reading.ac.uk/met-darc/) enjoying an international, diverse and stimulating research environment. The postholder will be also affiliated at the National Centre for Earth Observation (NCEO, https://www.nceo.ac.uk/) a distributed centre of over 100 scientists in the UK.
Candidates with a knowledge of, or possessing a PhD on, data assimilation and/or on discontinuous Galerkin methods will be given priority.
