Data

• Models driven by
• HWind (HRD) analysis wind
• ANA forecast wind
• Data comparison stations
• FCMP wind
• NOAA/NOS wind
• NOAA/NOS surge
• USGS surge
• Land cover / land use

Summary

• Significant progress in storm surge and
  inundation modeling has been made by academic and
  government researchers
• Regional Testbed is needed compare models and
  model results and to help transition research
  results to government operational agencies
