ECMWF was created by a Convention that came into force on 1 November 1975 and was amended on 6 June 2010.
The governing bodies are the Council, the Director-General, and the Council's advisory committees, whose functions are defined in the Convention.
The ECMWF Council is made up of representatives from ECMWF's Member States and meets twice a year.
The Director-General is the Centre's chief executive officer, and is appointed by the Council. He or she reports to the Council, and has overall responsibility for the work of the Centre.
