Coordinated Enhanced Observing Period (CEOP) an Element of WCRPinitiated by GEWEX EOP1: Jul.-Sep EOP3: Oct Sep EOP4: Oct Dec. 2004

CEOP SCIENTIFIC OBJECTIVES LONG-TERM GUIDING GOAL To understand and model the influence of continental hydroclimate processes on the predictability of global atmospheric circulation and changes in water resources, with a particular focus on the heat source and sink regions that drive and modify the climate system and anomalies. OVERALL OBJECTIVE 1 To better document and simulate water and energy fluxes and reservoirs over land on diurnal to annual temporal scales and to better predict these on temporal scales up to seasonal for water resources application. Water & Energy Simulation & Prediction (WESP) OVERALL OBJECTIVE 2 Document the seasonal march of the monsoon systems, assess their living mechanisms, and investigate their possible physical connections.
