Observations
Currently, well over 10 000 manned and automatic surface weather stations, 1 000 upper-air stations, 7 000 ships, 100 moored and 1 000 drifting buoys, hundreds of weather radars and 3 000 specially equipped commercial aircraft measure key parameters of the atmosphere, land and ocean surface every day. Add to these some 30 meteorological and 200 research satellites to get an idea of the size of the global network for meteorological, hydrological and other geophysical observations.
What we do
Observations, Research
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
Observations, Data exchange, Research, Applications
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.
National Meteorological and Hydrological Services
Weather, Observations
WMO assists National Meteorological and Hydrological Services, especially those of developing and least developed countries, in their efforts to contribute in the most effective manner to the national development and to become full partners in global collaborative efforts.
Focus areas
Applications, Data exchange, Technology transfer, Environment, Natural hazards, Observations, Oceans
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.
