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”
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
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!
A Common Cyberinfrastructure for Model Data 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 Structured Grids Unstructured Grid 10 nodes 5x5 6x3 Variety of Stretched Vertical Coordinates
Testbed Goals • Develop skill metrics and assess models in three different regions and dynamical regimes • Build a common infrastructure for access, analysis and visualization of all ocean model data produced by the National Backbone and the IOOS Regions. • Transition models, tools, toolkits and other capabilities to federal operational facilities • Build stronger relationships between academia and operational centers through collaboration

Inundation Extra-tropical – Gulf of MaineTropical – Gulf of Mexico- 4 models: 3 unstructured grid +1 structured grid- Coupled wave-storm surge-inundation (TWL)- Consistent forcing, validation and skill assessment using existing IMEDS tool • Extensive observational data sets for historical storms Ike, Rita and Gustav in standard formats • SURA has provided supercomputer resources Extratropical Grid Tropical Grids for Galveston Bay
Inundation Successes • High quality grids, forcing, and extensive observational data for specific storms publically available for community testing • Direct comparisons between operational inundation models (e.g., SLOSH) with academic community models • Community building within research community by modeling groups working together • Improved academic - government relationship through partnership

Future Work for the Testbed • Expand to more regions and more coastal issues • Examine more factors (e.g. data assimilation approaches, model coupling) • Build out the cyberinfrastructure(more functionality, toolboxes for other languages, web services, outreach, training) • Find a way to sustain testbed activities
