Who we are
The European Centre for Medium-Range Weather Forecasts (ECMWF) is an independent intergovernmental organisation supported by 34 states.
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.
The organisation was established in 1975 and now employs around 270 staff from more than 30 countries. ECMWF is one of the six members of the Co-ordinated Organisations, which also include the North Atlantic Treaty Organisation (NATO), the Council of Europe (CoE), the European Space Agency (ESA), the Organisation for Economic Co-operation and Development (OECD), and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT).
ECMWF is based in Reading, UK.
What we do
ECMWF's core mission is to:
- produce numerical weather forecasts and monitor the Earth-system;
- carry out scientific and technical research to improve forecast skill;
- maintain an archive of meteorological data.
To deliver this core mission, the Centre provides:
- twice-daily global numerical weather forecasts;
- air quality analysis;
- atmospheric composition monitoring;
- climate monitoring;
- ocean circulation analysis;
- hydrological prediction.
We also provide advanced training to scientific staff in our Member and Co-operating States and assist the World Meteorological Organization with its programmes. We make 25% of the supercomputing facilities available to Member States.
