Scientists: high-resolution Earth-system data assimilation and observations for Destination Earth (multiple vacancies)

You are here

ECMWF has multiple exciting opportunities for Scientists to help shape and deliver DestinE developments in collaboration with partners throughout Europe. These roles will contribute to the provision of much improved prediction capabilities. They will do so, through advancing the use of observations and data assimilation capabilities of the ECMWF’s Integrated Forecasting System (IFS) towards enabling the delivery of the weather-induced extremes digital twin, which will rely on high-resolution (km-scale) medium-range simulations to drive much enhanced weather induced extremes predictions.

The roles advertised through this vacancy offer a unique opportunity to work on high-resolution data assimilation and usage of Earth-system observations at a cutting-edge numerical weather prediction centre. They cover the following thematic areas:

  • Area 1: Improved use of high spatial resolution observations, such as raw geostationary radiances, and provision of simulated imagery
  • Area 2: Observation handling and data assimilation developments supporting more frequent 4D-Var analysis updates
  • Area 3: Data assimilation developments in support of high-resolution atmospheric 4D-Var, including support to GPU adaptation of data assimilation codes and other related technical developments
  • Area 4: High-resolution land data assimilation and land-atmosphere coupling, including support to GPU adaptation of data assimilation codes and other related technical developments

The successful candidates will join the teams working on the use of Earth-system observations and the development of the data assimilation system of ECMWF Integrated Forecasting System. They will develop efficient observation processing, and improve the observation modelling, screening, bias correction and observation error modelling to support a coupled high-resolution land-atmosphere-ocean-sea-ice assimilation system. They will also develop and improve the data assimilation methods themselves, in particular aspects essential to km-scale initialisation and more frequent analysis updates.

The candidates’ work will shape, test and demonstrate the advanced capabilities of the weather-induced extremes digital twin. A particular focus of this twin will also be on developing flexible modelling interfaces with water, food, energy, health and risk modelling applications as integral parts of the digital twin.

These science developments will be implemented through advanced software and hardware technology solutions deployed by federated workflows on distributed extreme-scale high-performance computing (e.g. EuroHPC) and data handling infrastructures.

The successful candidates will join existing teams in ECMWF’s Research Department and strongly collaborate with other teams across ECMWF to demonstrate a successful weather-induced extremes digital twin implementation in the first phase of DestinE.  

The successful candidates will also support the relationships with ECMWF’s DestinE partners ESA and EUMETSAT, interact with external contractors as required, and help with communications & outreach activities with dedicated partners of the consortia contributing to the DestinE implementation, stakeholders and the user communities, and contribute to regular progress reports to the European Commission.

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