International co-operation, such as the gathering of global observational information, is essential to the work of all national weather services. Several intergovernmental organisations have been set up as an efficient way to co-ordinate these activities and share resources for research, education, training and technical methodologies.
The World Meteorological Organization (WMO) is a specialised agency of the United Nations, comprising of 188 Country Members and based in Geneva.
The European Centre for Medium-range Weather Forecasts (ECMWF) is an intergovernmental organisation supported by 18 European States — Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
EUMETSAT is an intergovernmental organisation created through an international convention agreed by 18 European Member States — Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Turkey and the United Kingdom. These States fund the EUMETSAT programmes and are the principal users of the systems.
EUMETSAT also has nine co-operating states: Slovak Republic, Hungary, Poland, Croatia, Republic of Serbia and Montenegro, Slovenia, Romania, the Czech Republic and Latvia.
EUMETSAT’s primary objective is to establish, maintain and exploit European systems of operational meteorological satellites. EUMETSAT is responsible for the launch and operation of the satellites and for delivering satellite data to end users, as well as contributing to the operational monitoring of climate and the detection of global climate change.
EUMETNET is a network grouping of 19 European national meteorological services which aims to make more efficient use of resources. It provides a framework to organise co-operative programmes between its members in fields such as data processing, basic forecasting products and research and development. Through EUMETNET programmes, the members aim to develop their collective capability to serve environment management and climate monitoring and provide all European users with the highest quality meteorological information.
ECOMET (the Economic Interest Grouping of the national meteorological services of the European Economic Area) was set up in 1995 to ensure fair competition in the field of meteorological services.
The Conference of Commonwealth Meteorologists (CCM) is an informal network of the heads of the 53 Commonwealth meteorological and hydrological services. It meets once every four years to give directors the opportunity to discuss and resolve issues of mutual concern.
CCM is also continually working to provide and improve weather, climate and environmental services throughout the world.
