Experiments (CSEs).
The overall GHP mission was to “demonstrate the capability to predict changes inwater resources and soil moisture at time scales up to seasonal and interannual as acomponent of the World Climate Research Programme’s prediction goals for theclimate system.”

The Coordinated Enhanced Observing Period (CEOP) was part of the initial GHP
strategy to help coordinate the diverse GEWEX CSE activities to understand andmodel the influence of continental hydroclimate processes on the predictability ofglobal atmospheric circulation and changes in water resources.
As a contribution to ‘CEOP’, the CSEs identified high-quality in situ measurements(many of these are tower sites) at several global locations that would be able toprovide coordinated global measurements during the period 2001-2004.

THE REQUIREMENT FROM WCRP/GEWEX WAS TO
HAVE:
COORDINATED OBSERVATIONS AND INTEGRATEDDATA TO TAKE ADVANTAGE OF:(1) REFERENCE SITES IN GEWEX CONTINENTALSCALE EXPERIMENTS (CSEs),(2) SPACE AGENCY PLANS FOR A LARGE SUITE OF
EARTH OBSERVATION SATELLITES AND(3) IMPROVED MODEL AND PREDICTION TOOLS;ANDSOTHECOORDINATED

LONG-TERM GUIDING GOAL
To understand and model the influence of continental hydroclimate
processes on the predictability of global atmospheric circulation andchanges in water resources, with a particular focus on the heat source andsink regions that drive and modify the climate system and anomalies.

CONCLUSION:CEOP Phase 1 was an unequivocal success:· CEOP had developed a viable integrated observation/modeling, data
management/science system for water and energy cycle studies• CEOP had facilitated model evaluation with multi-platform
observations, promoting active participation from operational centers,
research institutes, and satellite agencies.
• CEOP Increased synergy between satellite, in-situ observations andassimilated data for both regional and global water cycle studies• CEOP Promoted international organization and coordination of water
cycle data processes, research through reference site participations
and workshops.
• CEOP Stimulated and coordinated regional monsoon water cycle field
campaigns, model intercomparison studies, regional water and energy
cycle studies , e.g. draft of a white paper “ Aerosol-water cycle
interaction: a new challenge to Monsoon climate research” based onan CEOP sponsored workshop in Xining, China, July 2006.

JSC Recommended Action
Items for GEWEXWCRP JSC Meeting Recommendations March 2006:• “JSC approved the plan for CEOP phase II,
subject to a technical review of the science plan byexperts from each WCRP project, in order to proposeways to maximize synergies and to prevent potential
overlaps with existing WCRP activities.”•“GEWEX should propose to next JSC aplan to reorganize its structure in order tobetter integrate CEOP agenda in itspanels.”
