1. A Super-Regional Modeling Testbed for Improving Forecasts of Environmental Processes for the U.S. Atlantic and Gulf of Mexico Coasts Don Wright, SURA Principal Investigator Rich Signell, USGS Technical Advisory and Evaluation Group Chair

2. Testbed Origin - FY10 IOOS Budget “$4,000,000 is for a competitive extramural regional test bed… to understand, predict, and mitigate the consequences of both extreme events and chronic conditions in the U.S. Atlantic and Gulf regions. Such a test bed should include no less than 20 academic partners and research institutions to guarantee… community-modeling”

3. Improving Forecasts of Coastal Environmental Processes Factors: Open boundary conditions, met and river forcing conditions, physics vs. parameterizations, data assimilation approach, amount of data assimilated, numerics, vertical and horizontal resolution, model coupling. “Which model is better?” is often not the right question. What factors in the simulation resulted in a better solution? How much better? At what cost? Improving cyberinfrastructure leads to greater access by more people, and leads to faster improvements

4. Defining Improvement To measure improvement for environmental processes, we need to define skill metrics for specific environmental processes and often for specific region Inundation, search and rescue, deep oil spills, navigation, hypoxia, harmful algal blooms, diver operations, ocean energy siting, beach erosion, regional impact of climate change, all require different skill metrics Operational centers need community help in this process – too broad for the National Backbone!

5. The ocean community needs a common cyberinfrastructure to access, analyze and display data from the different models: each model currently has their own standards and toolsets A Common Cyberinfrastructure for Model Data Structured Grids Unstructured Grid 5x5 6x3 10 nodes Variety of Stretched Vertical Coordinates

6. 1.Develop skill metrics and assess models in three different regions and dynamical regimes 2.Build a common infrastructure for access, analysis and visualization of all ocean model data produced by the National Backbone and the IOOS Regions. 3.Transition models, tools, toolkits and other capabilities to federal operational facilities 4.Build stronger relationships between academia and operational centers through collaboration Testbed Goals
