ECMWF – Scientist – Ocean Assimilation

ECMWF, Shinfield Park, Reading, UK
Closing date: 24 January 2019

Summary of the role
In 2016, ECMWF committed to a new strategy up to 2025. The strategy aims to improve medium-range, extended range and seasonal forecasts by better representing processes taking place on a range of timescales in multiple Earth System components. This requires effort to raise the scientific and technical capability for non-atmospheric components of the Earth System assimilation and modelling. One aspect of this is increased emphasis to the ocean. This post will develop ocean data assimilation, with some aspects developed in-house and others in partnership with external agencies. The job holder will also support activities to integrate the ocean component fully into the Object Orientated Prediction System (OOPS), which will require support to aspects of the ocean model, in collaboration with the Earth System Modelling and Integrated Forecast Systems Sections within the Research Department. This will support ECMWF’s goal of a coupled ocean-atmosphere data assimilation system.

ECMWF is looking to recruit a scientist who will work on the scientific and technical development of the ocean data assimilation, using modern code architectures, and with the longer-term goal of a coupled ocean-atmosphere data assimilation system capable of ingesting raw Level-1 observations from satellites and in situ measurements to create a balanced initial state both in the ocean itself, and between ocean and atmosphere. The focus will be on the ocean component of the data assimilation. This position will require both state-of-the-art scientific research but also a strong technical capability, as well as work needed to implement changes, and subsequently provide expert support, to the operational system.

The position sits within the Earth System Assimilation Section at ECMWF and will report to the Coupled Data Assimilation Team Leader.

Main duties and key responsibilities

  • Integrating ocean DA developments targeting an ECMWF SST analysis
  • Contributing to the scientific and technical development, as well as monitoring of the ocean data assimilation, within the Object Orientated Prediction System (OOPS)
  • Contributing to the configuration of operational ocean reanalyses and real-time analyses, including updated observational data sets and latest methodology
  • Supporting other teams in the Research Department in related technical developments
  • Integrating developments from external partners, both through the NEMOVAR consortium and more generally

Grade remuneration
The successful candidate will be recruited at the A2 grade, according to the scales of the Co-ordinated Organisations and the annual basic salary will be £59,228.40 NET of tax. This position is assigned to the employment category STF-C as defined in the Staff Regulations.

Full details of salary scales and allowances are available on the ECMWF website at, including the Centre’s Staff Regulations regarding the terms and conditions of employment.

Starting date: As soon as possible.
Length of contract: Four years, with the possibility of a further contract.
