An overview of who we are can be found in the Who we are section. Below, we offer a breakdown of some of the essential facts relating to our work (as of July 2016).

Background

  • 22 Member States and 12 Co-operating States.
  • About 300 employees from over 30 countries.
  • Established in 1975.

Finance

  • In 2014, ECMWF’s annual budget of almost £55 million was funded largely by annual contributions from the Member and Co-operating States, according to a scale based on their gross national income. Significant funding is also provided from the sale of forecast and data products and from a variety of externally funded projects.
  • The sponsorship department in the UK Government for ECMWF is the Department for Business, Energy and Industrial Strategy (BEIS).

Forecasts

  • The term 'medium-range' refers to time periods up to about 2 weeks ahead. Extended forecasts are also produced for monthly and seasonal timescales.
  • The weather services of ECMWF Member States receive ECMWF's numerical weather prediction data in real-time – 24 hours a day, 7 days a week.
  • Twice daily forecasts are produced for weather services and businesses.
  • Commercial licences held by customers in over 30 countries.
  • ECMWF uses advanced computer modelling techniques to analyse observations and predict future weather.
  • ECMWF’s assimilation system uses 40 million observations a day from more than 50 different instruments on satellites, and from many ground-based and airborne measurement systems.

Research

  • ECMWF has research partnerships with national meteorological services of the Member States and Co-operating States.
  • We also carry out a number of research projects co-ordinated and financed through the European Union, European space agencies and national funding sources.

Supercomputing

  • ECMWF's supercomputers are among the largest of their type in Europe.
  • Our supercomputers operate with a sustained speed of more than 330 trillion floating point operations per second.
  • Our supercomputers serve a variety of purposes, with 50% capacity used for research, 25% used by Member States and 25% used for production of operational forecasts.
  • The ECMWF meteorological data archive (MARS) is the largest in the world and continues to grow. As of June 2016, it contains around 107 petabytes of operational and research data, with about 120 terabytes being added daily. More than 260 billion meteorological fields are stored in MARS.
