Merger of the
Coordinated Enhanced Observing Period (CEOP)
into the
Coordinated Energy and Water Cycle Observations Project (CEOP)
At their 2007 meeting, the GEWEX Scientific
Steering Group approved the merger of the GEWEX Hydrometeorology Panel (GHP) and the
Coordinated Enhanced Observing Period into the Coordinated
Energy and Water Cycle Observations Project (CEOP), which now oversees all GEWEX
Hydroclimate projects. To view a paper with the rationale for this merger, click here. CEOP, which is co-chaired by
Drs. Toshio Koike and John Roads, coordinates the plans and the focus of
scientific issues related to the development and implementation of the Regional
Hydroclimate Projects (RHPs) and has oversight over all GEWEX regional hydroclimate and
land-surface projects. The principal task of CEOP is to guide these projects in the
goal of achieving demonstrable skill in predicting changes in water resources and soil
moisture as an integral part of the climate system up to seasonal and annual time scales.

Background
The Coordinated Enhanced Observing
Period (2001-2006) was initiated as a major step towards bringing together the
research activities in GHP/GEWEX and related projects in WCRP (CLIVAR; CLiC). It was
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.
The Coordinated Enhanced Observing
Period set down the ground work for (1) linking satellite and in situ data as an
integrated data set necessary for providing added value cal/val activities; (2) performing
transferability studies leading to greater global applications; (3) responding to specific
science issues; and (4) defining future needs for sensors and space coverage to reduce
uncertainties in climate change predictions. In 2002, CEOP adopted an additional
objective, "To verify the physical consistency of the products provided by the
elements of the international global observing system by systematic comparison with the
data acquired by Continental Scale Experiments (CSEs) site-specific observations through
GCM simulations which emphasize the behavior of the global energy and water cycles."
The coordinated enhanced observation and model output generation were completed
during the first Enhanced Observing Period (EOP-1), which extended from July-September
2001, the EOP-3 (from October 2002-September 2003), and the EOP-4 (from October
2003-December 2004).

Observing Period, see the University of Tokyo CEOP web site.
