IOOS Modeling Testbed (testbed.ioos.us)

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

Structured Curvilinear Orthogonal Grid

Stretched surface and terrain following vertical coordinates

Curvilinear orthogonal horizontal coordinates

NetCDF Climate and Forecast (CF) Conventions provide a solution
