Scientist - Hydrological Forecast Evaluation
Vacancy No.: VN17-09
Section: Evaluation Section
Job Ref. No.: STF-PL/17-09
Reports to: Team Leader
Publication Date: 21 July 2017
Closing Date: 17 August 2017
ECMWF is both a research institute and a 24/7 operational service, producing and disseminating numerical weather predictions to its Member States. This data is fully available to the national meteorological services in the Member States. The Centre also offers a catalogue of forecast data that can be purchased by businesses worldwide and other commercial customers. The supercomputer facility (and associated data archive) at ECMWF is one of the largest of its type in Europe and Member States can use 25% of its capacity for their own purposes.

ECMWF has long recognised the value of high-quality forecasts in mitigating the effects of natural disasters.
Recognising that floods are among the costliest natural disasters in Europe, the European Commission instigated the development of the European Flood Awareness System (EFAS) at its Joint Research Centre (JRC). Development and testing were carried out in close collaboration with national hydrological and meteorological services, European civil protection agencies (through the Emergency Response and Coordination Centre (ERCC)), and other research institutes. Since 2011, EFAS has been part of the Copernicus Emergency Management Service (CEMS) and it became fully operational in 2012.
EFAS helps to protect European citizens, the environment, property and cultural heritage when major floods occur by providing:
- added-value early flood forecasting products for hydrological services;
- unique overviews of current and forecast floods in Europe more than 3 days in advance;
- a European network of operational hydrological services.
Current products include pan-European overview maps of flood probabilities up to 15 days in advance and detailed forecasts at stations where the national services are providing real-time data. More than 50 hydrological services and civil protection services in Europe are part of the EFAS network.
Several European organisations, including ECMWF, are responsible for running the operational EFAS system. As well as providing ensemble meteorological forecasts, ECMWF:
- acts as the EFAS Computational centre, the heart of data processing and model calculations;
- hosts the web interface for the EFAS Information System.
Alongside this, ECMWF co-operates with the JRC in the provision of the pre-operational Global Flood Awareness System (GloFAS). GloFAS scales the approaches used in EFAS to the global domain and is expected to go fully operational as part of the Copernicus EMS during 2017.
Summary of the role
The focus of the position will be the evaluation of hydrological forecasts produced at ECMWF, especially those from EFAS and GloFAS. Currently, overall skill assessments are undertaken during the development of improvements to the EFAS and GloFAS systems, but the methods employed are not always consistent across the different products and forecasting ranges. Whilst verification of hydrological forecasts against pseudo-observations is conducted every month, in-situ observational-based verification and model diagnostics occur on a more ad-hoc basis after major flood events have been reported.
New developments are envisaged to move towards a more systematic evaluation of hydrological forecasts, and for methods to be better aligned with techniques currently applied to the ECMWF Integrated Forecasting System (IFS). More specifically, the developments should:
- develop a systematic, consistent approach to hydrological forecast evaluation, including skill metrics, performance verification and diagnostics;
- build synergies between the evaluation of CEMS (e.g. EFAS and GloFAS) products and the approaches developed for ECMWF's IFS evaluation
The role may also include further work associated with addressing these two objectives.
Main duties and key responsibilities
- Maintaining and developing approaches and tools for the evaluation of forecasts from the European and Global Flood Awareness Systems and ECMWF's hydrological forecasts more generally
- Investigating the use of hydrological observations within the evaluation of hydrological forecasts
- Working closely with the team delivering ECMWF's CEMS activities, scientists from the Forecast Department involved in ECMWF's evaluation activities, and with the EFAS data collection and dissemination centres
- Leading monthly reporting of hydrological forecasting performance
- Documenting tools and results through scientific documents and publications
- Good communication and interpersonal skills
- Excellent analytical and problem-solving skills, and a proactive approach
- Flexibility, with the ability to adapt to changing priorities and user needs
- Dedication and enthusiasm to work independently and in a small team
- Eagerness to work in a collaborative environment for shared ownership
- Ability to work across disciplines and with different international organisations
