Global Climate Observing System (GCOS)

The Global Climate Observing System (GCOS) is based upon the coordination of existing and planned operational observing systems and research programmes for observing global climate.

GCOS also promotes further developments of these systems and programmes to ensure the required scope and continuity of observations for climate analysis and prediction.

It was established following the signing on 9 April 1992 of a Memorandum of Understanding by WMO, IOC of UNESCO, UNEP and ICSU to establish a Global Climate Observing System (GCOS).
