Surface Fluxes in CEOP was initiated as a major step towards bringing together the research activities in GHP/GEWEX and related projects in WCRP (CLIVAR; CLi. C). CEOP initially developed into an important but separate element of WCRP. It has since come back into the GEWEX fold in its merge with GHP to form the Coordinated Energy and water-cycle Observation Project. CEOP been endorsed by the Integrated Global Observing Strategy Partnership (IGOS-P) as the first element of the IGOS-P Integrated Global Water Cycle Observations (IGWCO) Theme.
