GEWEX Hydroclimatology Projects

The GEWEX Hydroclimatology Panel (GHP), formerly the Coordinated Energy and Water Cycle Observations Project (CEOP), oversees all GEWEX hydroclimatology projects, and is co-chaired by Dennis Lettenmaier and Jan Polcher. GHP 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 GHP 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.

AMMA - African Monsoon Multidisciplinary Analysis Project	Thierry Lebel
BALTEX - Baltic Sea Experiment	H.-J. Isemer
HyMeX - HYdrological cycle in the Mediterranean Experiment	Philippe Drobinski
LBA - Large-Scale Biosphere-Atmosphere Experiment in Amazonia	Jair Maia

The former GEWEX Continental Scale Experiments (CSEs) have been renamed Regional Hydroclimate Projects (RHPs) to better reflect the changing priorities of the new 2007 GHP/CEOP merger and the connection between the science and data components.

See the technical and scientific criteria for RHPs.
