World Meteorological Organization

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