Challenge: Support diverse array of NOAA mission needs
Forecaster requirements: - Provide predictive information for full 3D ocean, US coastlines, and
Great Lakes (potential nesting strategy).
- Application will define model choice(s), spatial and temporal resolution,
validation metrics, and operational turn-around time.
- Bias correction (DA).

NATIONAL WEATHER SERVICE Building a Weather-Ready Nation // 14IOOS Coastal Ocean Modeling Testbed
Mission: To use applied research and development to accelerate the transition of scientific and
technical advances from the coastal ocean modeling research community to improved operational
ocean products and services (i.e. via research to operations and also operations to research).
2018 – 2021 Themes • 6 projects; 3 years
• Coastal Coupling with • Readiness Levels: 4-6 -> Advance 2
National Water Model steps over the course of the project
• Ecoforecasting • Community development plus
• Enhancements to the stakeholder engagement (Science PI
NOS OFS portfolio and Transition PI)
Focusing on transition of research to operations; other testbeds prioritize more rigorous
testing of forecast improvement.
