World Meteorological Organization (1873, Geneva, 200 Staff;

WMO is a specialized agency of the United Nations dedicated to fostering international cooperation and coordination on the state and behavior 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.

WMO programmes facilitate and promote:

  • the establishment of networks of observational stations to provide weather, climate and water-related data;
  • the establishment and maintenance of data management centres and telecommunication systems for the provision and rapid exchange of weather, climate and water-related data;
  • the creation of standards for observation and monitoring in order to ensure adequate uniformity in the practices and procedures employed worldwide and, thereby, ascertain the homogeneity of data and statistics;
  • the application of science and technology in operational meteorology and hydrology to aviation, transport (air, land and maritime), water resource management, agriculture and other focus areas;
  • activities in operational hydrology as well as closer cooperation between National Meteorological and Hydrological Services in states and territories where they are separate; and
  • the coordination of research and training in meteorology and related fields.

Seven focus areas:

  • Weather
  • Climate
  • Water
  • Cryosphere
  • Environment
  • Natural hazards and disaster risk reduction
  • Oceans

29 programs are presently engaged in 48 projects, e.g., Food Security and Global Framework for Climate Services.

An extensive library is available including: conference, annual, statistical and other expert reports as well as publications, working papers, journals, newsletters and information dossiers on meteorology and related topics.

Examples of recent reports:

  • WMO Statement on the State of the Global Climate in 2019, (2020, 39p)
  • Count every drop: every drop counts (2020, 4p)
  • Report of the Fifth Session of the CAS Environmental Pollution and Atmospheric Chemistry Scientific Steering Committee (2020, 36p)
