Hydrological Sciences Branch Seminar: Rick Lawford

International GEWEX Project Office (IGPO)
This talk will review the activities of the Global Energy and Water Cycle Experiment (GEWEX) with an emphasis on activities related to its Hydrometeorology, Modeling and Prediction, and Radiation Panels as well as to the Coordinated Enhanced Observing Period (CEOP). GEWEX directs its efforts towards the development of databases at global and regional scales to be used in the analysis of the climate system, the conduct of regional or local scale process studies and the testing of simulation and prediction models. Currently GEWEX is developing a roadmap for its second phase (2003-2012) that places more emphasis on the exploitation of its databases and the knowledge and modeling capabilities developed in its first phase (1990-2002) to answer central questions regarding energy and water cycles, their role in the climate system, and seasonal to interannual prediction. GEWEX studies also include the application of global scale products to explore the causes of regional water cycle trends that may have implications for the globe on longer time scales. In addition, through its Water Resources Application Project (WRAP), GEWEX is contributing to the local application of its data and prediction products. A major contribution to regional scale hydrology comes through CEOP. In many of these activities GEWEX has benefited from the contributions of the Goddard Space Flight Center (GSFC). GEWEX anticipates that it will continue to benefit from this expertise as it continues to develop its second phase. In addition to the contributions to GEWEX, this talk will also present opportunities that exist for GSFC to play a role in the Integrated Global Water Cycle Observations (IGWCO) theme of the Integrated Global Observing Strategy-Partnership (IGOS-P) and in the Water Cycle Societal Benefit Area of the Global Earth Observation System of Systems (GEOSS). The IGWCO was established in 2003, to bring together international programs and national agencies to develop a framework for guiding decisions regarding priorities and strategies for the enhancement of water cycle observations. GSFC research could provide guidance on key questions that need to be addressed in the design of water cycle observation systems. The presentation will also briefly describe the most recent plans for GEOSS and identify potential GSFC contributions. The talk is intended to provide an introduction to specific discussions about areas where individual GSFC scientists may wish to actively pursue stronger links with GEWEX.
