Our mandate

Our mandate

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

What we do

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.  

How we do it

Through its Technical Commissions, Programmes, Projects and Regional Offices as well as by synergistic partnerships, WMO facilitates the maintenance and expansion of its Members' atmospheric, oceanographic and land-based observational networks; the free unrestricted exchange of the resulting data and information; and related capacity development and research in order to optimize the production of weather, climate and water-related services worldwide.

Focus areas

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.

Development Partnerships

There is an urgent need to go beyond business as usual when it comes to  strengthening hydromet capacity in developing countries through effective partnerships. In June 2019, the World Meteorological Congress adopted a sweeping reform including a resolution to scale up effective partnerships for investments in sustainable and cost-efficient infrastructure and service delivery.

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.

Who we are

As weather, climate and the water cycle know no national boundaries, international cooperation at a gl
