As weather, climate and the water cycle know no national boundaries, international cooperation at a global scale is essential to implement an Earth system approach for the development of meteorology, climatology, operational hydrology and related environmental services as well as to reap the benefits from their application. WMO provides the framework for such international cooperation.
As a specialized agency of the United Nations, WMO is dedicated to international cooperation and coordination on the state and behaviour of the Earth’s atmosphere, its interaction with the land and oceans, the weather and climate it produces, and the resulting distribution of water resources.
Through its Technical Commissions, Programmes, Projects and Regional Offices, as well as its synergistic and public-private partnerships, WMO facilitates and coordinates an Earth system approach to the gathering and free exchange of observations, promotion and integration of research and the development and delivery of services in the areas of weather, climate and water.
Within its mandate in the areas of weather, climate and water, WMO focuses on many different aspects and issues from observations, information exchange and research to weather forecasts and early warnings, from capacity development and monitoring of greenhouse gases to application services and much, much more.
Vision, Mission, Strategic Planning
WMO provides world leadership and expertise in international cooperation in the delivery and use of high-quality, authoritative weather, climate, hydrological and related environmental services by its Members, for the improvement of the well-being of societies of all nations.
