GHP Regional Hydroclimate Projects (RHPs)

RHPs are generally large, regionally-focused multidisciplinary projects that aim to improve the understanding and prediction of that region’s weather, climate, and hydrology. All RHPs address the physical processes surrounding water and energy exchanges within a region, thus addressing the GEWEX Science Questions. Most RHPs are broader than this, often addressing questions related to the biosphere and carbon cycle, human interaction in the landscape, and even socio-economic factors.

In order for a new project to be recognized as an RHP, it must satisfy the RHP criteria. Examples of documentation for past and present RHPs can be found in the RHP Library.

Current RHPs

  • HyMeX: HYdrological cycle in the Mediterranean Experiment
  • CCRN: Changing Cold Regions Network


Initiating RHPs 

The potential RHPs below are at various stages of development. If you are interested in getting involved with one, please contact the International GEWEX Project Office.

  • HyVic: Hydrology of Lake Victoria Basin
  • OzEWEX: Australian Energy and Water Exchanges
  • Baltic Earth: Earth System Science for the Baltic Sea Region


Proposed RHPs

  • ANDEX: Hydroclimate Research Program for the Andes
  • PannEx: a regional hydroclimate project for the Pannonian Basin


Completed RHPs

Several RHPs have been completed. These RHPs have left legacy data sets and knowledge that is often still accessible through their websites. A more detailed account of completed RHP plans, documentation, and articles can be found in the RHP library.

  • MAHASRI: Monsoon Asian Hydro-Atmosphere Scientific Research and Prediction Initiative (ended 2016)
  • NEESPI: Northern Eurasia Earth Science Partnership Initiative (ended 2015)
  • BALTEX: Baltic Sea Experiment (ended 2013)
  • LPB: La Plata Basin (ended 2012)
  • MDB: Murray-Darling Basin (ended 2011)
  • LBA: Large-Scale Biosphere-Atmosphere Experiment in Amazonia
  • AMMA: African Monsoon Multidisciplinary Analysis Project
  • CPPA: Climate Prediction Program for the Americas (formerly GEWEX Americas Prediction Project – GAPP) (ended 2010)
  • GAME: GEWEX Asian Monsoon Experiment (ended 2005)
  • MAGS: Mackenzie GEWEX Study (ended 2005)
  • GCIP: GEWEX Continental-scale International Project (ended 2001)


RHP Library

The RHP Library contains proposals, white books, science plans, and other documentation for some of the past and present RHPs.
