5 An example of a past CSE (GCIP) GCIP implementation was structured to meet the needs of: 1) NOAA which was committed to transitioning GCIP research into its operations through the NOAA core project. 2) Scientists who needed to access reliable data sets. 3) GEWEX which needed regional testbeds to evaluate its products. 4) NASA which needed science projects to exercise its satellite products and to develop new applications. Was it effective? Quote by Ken Mitchell, NCEP

6 YEAR A BRIEF HISTORY OF RHPs (Focus on the USA) ERA I ISLSCP

7 Era 1: Perception: Closure of water balances over the basins was a central issue for CSE studies. They also advanced process understanding but with a goal of improved atmospheric and coupled land- atmosphere modeling. Success Criteria: 1) Sustainable budgets 2) Ability to answer science questions: a) How well can one close the water budget for the basin? b) To what extent can models reproduce the patterns of precipitation, soil moisture and runoff seen in the basin? c) ability to address national/regional needs Regional Continental Scale Experiments Governance Structure: GEWEX SSG CSEs

9 YEAR A BRIEF HISTORY OF RHPs ERA II

10 Era 2: Perception: While single basin efforts allowed for focused efforts the relationships with other basins and other projects enabled the CSEs to expand their scope and make their results available to a broader user base. Success Criteria: Governance Structure: GEWEX SSG GHP CSEs

11 YEAR A BRIEF HISTORY OF RHPs ERA III

13 Era 3: Perception: Crosscuts were seen as a way of synthesizing the information from each CSE (or RHP) and promoting convergence and interoperational systems. Success Criteria: GEWEX Phase 2 goals: 1. Produce consistent descriptions of variability and trends 2. Enhance process understanding 3. Develop improved parameterisations 4. Interact with the wider WCRP community 5. Water resource and applications Governance Structure: GEWEX SSG GHP CSEs Crosscuts CEOP

15 YEAR A BRIEF HISTORY OF RHPs (Focus on the USA) ERA IV NEESPI MAHASRI

16 Era 4: Perception: During ERA III, CEOP grew to be as large and complex as GHP. It was felt that a merger of GHP and CEOP would enhance CEOP contributions to GHP and would streamline the structure of CEOP. Success Criteria: The emphasis for CEOP was to ensure the delivery of data to the CEOP archives, to ensure the completion of the data archives, and to test out the CEOP information system. Governance Structure: GEWEX SSG CEOP GHP CEOP Data RHPs

17 Era 5: Present Perception: The GHP will be streamlined and structured with a review panel that will oversee the activities. A coordination panel will report to this review panel. Current projects will be reviewed to see if they are appropriate to continue in this new framework. Success Criteria: Success criteria are expected to arise from a May 2011 meeting of the GHP. There is an expectation that the RHPs will give priority to contributing to the GEWEX Imperatives. Governance Structure: GEWEX SSG GHP RHP Panel RHPs

18 Benefits of an RHP for an international program (Why GEWEX is a good partner) - RHPs develop a base of funded activities that make GEWEX stronger. - An RHP generates science that is of high relevance for other parts of the world and serves as a basis for intercomparisons, technology transfer and capacity building. - RHPs provide a basis for international collaboration in hydroclimatology. - RHPs facilitate strategies for the convergence and interoperability of models, observational procedures and research capabilities. This is facilitated by GEWEX criteria for RHPs. Opportunity areas include extremes, monsoons, land-atmosphere coupling, adaptation to climate change, linkages to other sectors (carbon, food, etc)

20 GEWEX Imperatives Datasets: Foster development of climate data records of atmosphere, water, land,and energy-related quantities, including metadata and uncertainty estimates. Analysis: Describe and analyze observed variations, trends and extremes (such as heat waves, floods and droughts) in water and energy-related quantities. Processes: Develop approaches to improve process-level understanding of energy and water cycles in support of improved land and atmosphere models. Modeling: Improve global and regional simulations and predictionsof precipitation, clouds, and land hydrology, and thus the entire climate system, through accelerated development of models of the land and atmosphere. Applications: Attribute causes of variability, trends and extremes, and determine the predictability of energy and water cycles on global and regional bases. Technology transfer: Develop new technologies and techniques for transition to operational applications in partnership with climate and hydro-met. service providers. Capacity building: Promote and foster capacity building throughtraining of scientists and outreach to the user community.

21 Considering the SRB RHP : Some Questions to be resolved What information is needed to more effectively manage water resources in the SRB? How can science done in support of GEWEX be used to address these problems? Is the scale of the Saskatchewan River Basin large enough for a GEWEX RHP? Is it too large to mount a comprehensive water budget study? Is it too small to provide a basis for improved atmosphere-hydrology models? What is the overall vision for an information system that can be put in place in an SRB RHP? What are the science questions that need to be addressed to support this vision of an information system? Are the observational systems and modelling capabilities in place to address those science questions? Which components in the system are already in place and could be linked together as a first order system? To what extent should this information system address groundwater? water quality? Water use?

22 Benefits of RHPs to individual scientists (or why you should be involved): - More predictable opportunities for funding. - New opportunities for collaboration. - Infrastructure support for data archival and access. - Access to targeted international/ national conferences, working groups and publication opportunities. - Membership in a scientific community.
