The World Meteorological Organization

The World Meteorological Organization (WMO) is a specialized agency of the United Nations.

It is the UN system's authoritative voice on the state and behaviour of the earth's atmosphere, its interaction with the oceans, the climate it produces and the resulting distribution of water resources.

WMO became the specialized agency of the United Nations in 1951 for meteorology (weather and climate), operational hydrology and related geophysical sciences.

WMO has a membership of 189 Member States and Territories.

As weather, climate and the water cycle know no national boundaries, international cooperation at a global scale is essential for the development of meteorology and operational hydrology as well as to reap the benefits from their application. WMO provides the framework for such international cooperation.

WMO facilitates the free and unrestricted exchange of data and information, products and services in real- or near-real time on matters relating to safety and security of society, economic welfare and the protection of the environment. It contributes to policy formulation in these areas at national and international levels.

WMO plays a leading role in international efforts to monitor and protect the environment through its Programmes. In collaboration with other UN agencies and the National Meteorological and Hydrological Services, WMO supports the implementation of a number of environmental conventions and is instrumental in providing advice and assessments to governments on related matters. These activities contribute towards ensuring the sustainable development and well-being of nations.

The Secretary General of WMO is Michel Jarraud, who was appointed in 2004.

The main governing body of WMO is the Congress which meets every four years, latest in 2011. The Executive Council is the executive body of the organization.

Denmark has been a member of WMO since 1951. Through this membership, Denmark contributes to the global observations and is obliged to maintain these observations in Denmark, Greenland and the Faroe Islands. Through its Meteorological Institute (DMI), Denmark also participates in the international exchange of information and data.
