1. Position information

Vacancy No.: VN19-19 Department: Copernicus Services Grade: A2 Section: CAMS Job Ref. No.: STF-PL/19-19 Reports to: Deputy Head of CAMS Publication Date: 10 April 2019 Closing Date: 16 May 2019

2. About ECMWF

ECMWF is both a research institute and a 24/7 operational service, producing and disseminating numerical weather predictions to its Member States. ECMWF carries out scientific and technical research directed to the improvement of its forecasts, collects and processes large amounts of observations, and manages a long-term archive of meteorological data. Satellite and in situ observations provide the information for up-to-date global analyses and climate reanalyses of the atmosphere, ocean and land surface. For details, see www.ecmwf.int/.

ECMWF has been entrusted to operate the Copernicus Atmosphere Monitoring Service (CAMS) and the Copernicus Climate Change Service (C3S) on behalf of the European Commission until 2021. Copernicus is the European Union (EU) flagship Earth-observation programme. The Copernicus programme ensures operational monitoring of the atmosphere, oceans, and continental surfaces, and provides reliable, validated information services for a range of environmental and security applications. Based on the exploitation of space based and in situ observations and models, Copernicus provides information services for land, marine, atmospheric and climate monitoring, as well as emergency management and security. For details, see www.copernicus.eu/.

The Copernicus Atmosphere Monitoring Service (CAMS) service provides consistent and qualitycontrolled information related to air pollution and health, solar energy, greenhouse gases and climate forcing, everywhere in the world. For details, see atmosphere.copernicus.eu/.

The Copernicus Climate Change Service (C3S) service provides authoritative information about the past, present and future climate, as well as tools to enable climate change mitigation and adaptation strategies by policy makers and businesses. For details, see climate.copernicus.eu/.

3. Summary of the role

The post-holder will work in the CAMS Development Section contributing to the further development of the CAMS global data assimilation and forecasting system and the Global Fire Assimilation System (GFAS). The successful candidate will work as part of a team to monitor and improve the impact of current satellite instruments and to implement and evaluate the use of new instruments.

4. Main duties and key responsibilities

The post-holder will contribute to the development of the data assimilation aspects in the CAMS global assimilation and forecasting system as well as the further development of the Global Fire Assimilation System (GFAS). The CAMS global forecasting system consists of specific schemes for representing processes related to aerosol, chemical species and greenhouse gases in ECMWF’s Integrated Forecasting System (IFS). The post-holder will work with internal ECMWF staff and externally contracted experts to improve the data assimilation code as well as introduce new observational data streams, such as for the Sentinels and other satellite missions. This also includes exploring the use of observations for additional atmospheric species to better constrain the forecasting system. In a similar way, the Scientist will work to improve the data assimilation code as well as introduce new observational data streams in the GFAS system.

  • Maintaining and further improving the data assimilation aspects of atmospheric composition in IFS
  • Introducing new observational data streams in the CAMS global data assimilation and forecasting system
  • Maintaining and further improving the Global Fire Assimilation System (GFAS)
  • Overseeing the work carried out in their area of expertise by external contractors for the execution of CAMS activities
  • Integrating and testing mature system developments prepared by external contractors into IFS and GFAS
  • Monitoring the performance of the operational GFAS system and troubleshooting when necessary in collaboration with the CAMS global production team
  • Assisting with technical tasks needed for running atmospheric composition in the IFS
  • Assisting the CAMS user support for responding to specialised user queries

5. Personal attributes

  • Excellent analytical and problem-solving skills with an independent and proactive approach, together with an interest in identifying, investigating and solving scientific and technical challenges
  • Good interpersonal and communication skills, particularly listening to and respecting the views of others
  • Dedication and enthusiasm to work in a team
  • Ability to collaborate with both internal and external experts who support the development of the CAMS global forecasting system and GFAS

6. Qualifications and experience required


A university degree, or equivalent, in a discipline related to meteorology, physics, mathematics or geosciences is required.

A PhD in a related subject is desirable but not essential.


Experience with developing and maintaining large scientific codes.

Experience with atmospheric data assimilation is desirable.

Experience with developing codes on high-performance computing facilities is desirable.

Experience working in projects and teams governed by tight schedules would be advantageous.

Knowledge, Skills and Language

Good knowledge of at least one high-level programming language such as C++ or Fortran.

Ability to work in a Linux-based environment.

A good knowledge of Python would be advantageous.

Candidates must be able to work effectively in English and interviews will be conducted in English.

A good knowledge of one of the Centre’s other working languages (French or German) would be an advantage.

7. Other information
