  3. The GCOS story

GCOS was established in 1992 to ensure that the observations and information needed to address climate-related issues are obtained and made available to all potential users. It is co-sponsored by the

  • World Meteorological Organization (WMO),
  • Intergovernmental Oceanographic Commission (IOC) of United Nations Educational, Scientific and Cultural Organization (UNESCO),
  • United Nations Environment Programme (UN Environment), and
  • International Council for Science (ISC).

The terms of reference of the co-sponsorship are detailed in the GCOS Memorandum of Understanding. The original version was signed in 1992 and was updated in 1998.

GCOS Memorandum of Understanding (1992)

GCOS Memorandum of Understanding (1998)

The GCOS programme stimulates, encourages, coordinates and facilitates the taking of needed observations by national or international organizations to support their own requirements as well as common goals. It provides an operational framework for integrating and enhancing the observational systems of participating countries and organizations into a comprehensive system focused on the requirements for climate issues. The GCOS programme does not directly make observations nor generate data products.
