About ECMWF

ECMWF is both a research institute and a 24/7 operational service, producing numerical weather predictions for its Member and Co-operating States as well as users around the world. ECMWF carries out scientific and technical research and analysis aiming to continuously improve global prediction. ECMWF processes in its high-performance computing facility large amounts of observations to provide up-to-date global analyses and climate reanalyses of the atmosphere, ocean and land surface.

Over the years, ECMWF’s partnership with the European Union has grown, and in 2014 ECMWF became an entrusted entity to operate the Copernicus Atmosphere Monitoring Service (CAMS) and the Copernicus Climate Change Service (C3S) on behalf of the European Commission until mid2021 and ECMWF is preparing plans for the next phase of the Copernicus Programme for the period 2021-2027.

Open positions

Both opportunities are for a Scientist to work on the H2020 NextGEMS project.

1. Scientist to work on km-scale coupled ocean modelling

The role of this position is to further develop the representation of the ocean in ECMWF’s Integrated Forecasting System (IFS) as part of NextGEMS.

NextGEMS aims to develop a new generation of global coupled Storm-Resolving Earth System Models (SR-ESMs), exploring kilometre-scale simulations (2-4 km both in the atmosphere and the ocean) with an explicit representation of essential Earth system processes, such as ocean mesoscale eddies and atmospheric deep convection. The NextGEMS project focuses its development around two European SR-ESMs, ICON coupled to ICON ocean and IFS coupled to both NEMO and FESOM-2.

The position sits in the Earth System Modelling Section of the Research Department. As member of the Numerical Methods team, there will be a lot of collaboration with both the Coupled Processes and Physical Processes Team members, so strong communication and interpersonal skills will be key in this role.

The successful candidate will develop an improved and flexible coupling between the atmosphere and the ocean that enables the coupling of IFS to two different ocean models, NEMO and FESOM-2, to initialise and conduct coupled simulations at 2-4km resolution (of the atmosphere and ocean), to improve efficiency and scalability of selected coupled configurations and explore different grid and configuration options for the ocean models.

The Scientist will help to identify model errors of IFS coupled to the two ocean models, through targeted diagnostics and numerical experimentation, in close collaboration with teams across ECMWF and the NextGEMS partners. They will also contribute to the communication and dissemination of these results to an extensive range of stakeholders.

2. Scientist to work on km-scale land-atmosphere modelling

The role of this position is to further develop the representation of the land-atmosphere interaction in ECMWF’s Integrated Forecasting System (IFS) as part of NextGEMS.

NextGEMS aims to develop a new generation of global coupled Storm-Resolving Earth System Models (SR-ESMs), exploring kilometre-scale simulations (2-4 km both in the atmosphere and the ocean) with an explicit representation of essential Earth system processes, such as ocean mesoscale eddies, atmospheric deep convection and certain orographic processes.

The position sits in the Earth System Modelling Section of the Research Department. As member of the Coupled Processes team, there will be a lot of collaboration with the Physical Processes and Numerical Methods Teams members, so strong communication and interpersonal skills will be key in this role.

The successful candidate will evaluate and improve the representation of the land surface and of its coupling with the atmosphere at km-scales in the IFS, initialise and conduct coupled simulations at 2- 4km resolution, explore the benefits of a km-scale representation of the land surface on near surface meteorology, hydrology, and atmospheric circulation.

The Scientist will help to identify and address model errors in the IFS at km-scale, through targeted diagnostics and numerical experimentation, in close collaboration with teams across ECMWF and NextGEMS partners. They will also contribute to the communication and dissemination of these results to a wide range of stakeholders.

3. Location

Whilst these positions will be based in Bonn, Germany, there will be a lot of collaboration with staff based at the HQ in Reading, United Kingdom so it is anticipated that visits to the HQ in Reading will be required.
