  11. Joint Hurricane Testbed Process • Managed through the NOAA USWRP • Designed to accelerate R2O at the USWRP • Principal Investigators apply for funding through NOAA • A seven member Steering Committee rates all proposals • Funded projects are tested during one or two hurricane seasons in conjunction with NHC/EMC points of contact • At the project’s end, each are evaluated by NHC/EMC staff • Implementation of successful projects are then carried out by NHC/EMC staff/PIs • 1) Number of projects supported: 62 • 50 completed, 35.5 accepted for operational implementation, 5 rejected • 9.5 completed but pending further investigation • 12 projects in process: 12 • 2) Number of projects implemented: 31.5 • 10 numerical modeling related projects implemented by EMC/NCO • 21.5 projects implemented by NHC • 4 projects accepted but not yet fully implemented by NHC: 4 2001 – 2010 Summary

Experimental NAM HRW-ARW HRW-NMM Observed

  17. OPC thoughts on an Ocean-Coastal Testbed Ocean Prediction Center within NOAA family Traditional role Provides operational data and forecast services Facilitate R2O by linking science and users Future Directions An operational infrastructure to deliver relevant (e.g., clock driven) NOAA services Enabling a broad range of NOAA applications (e.g., ocean, coastal, ecological) services Must rely on NOAA (e.g., NOS) R&D resource and expertise for product development Potential testbed focus areas Physical forecasts and guidance Storm Surge / Inundation Wind Current Interactions Water quality services Sea Surface Salinity data applications and assessments Ocean Color data applications Enhancement of Harmful Algal Blooms, service delivery Ensemble (probabilistic) approaches

  18. Forces for Change • Increasing emphasis on multi-model ensemble approaches that build on the NCEP model suite • SREF • NAEFS • Climate Forecast System (EUROSIP) • Entering the JPSS era • More rapid access to hyperspectral data • GPS soundings • Higher resolution surface radiance data • All models run within ESMF • Models run concurrently • Hybrid vertical coordinate • Coupled • Spanning all scales • Operational Earth System model – more explicit hydro, climate and ecosystems applications ESMF-based System Global/Regional Model Domain Model Region 1 Model Region 2

  19. Model Production Suite Atmosphere Ocean Cryosphere Land • Predictions Driven by Global Observing Systems • Real-time operations require world’s largest computers • BIOLOGY/CHEMISTRY NOW BEING INCLUDED

  21. Ecosystem Prediction Predicting Sea Nettles in Chesapeake Bay Current Demonstration Ready for Transition* • Automatically generate daily nowcasts and 3-day forecasts of Sea Nettles, Chrysaora quinquecirrha, in Chesapeake Bay • Generated since 2002 • Important for water management and recreational purposes * Research initiated, developed and results demonstrated by NOS and NESDIS with regional partners and customers Predicted chance of encountering sea nettles, C. quinquecirrha, on August 17, 2007

  22. Recent Research Highlight from GFDL: High-resolution Ocean Modeling of DWH • Many of the oceanic consequences of climate change can best be explored with realistic high-resolution global ocean climate models, like those now being developed at GFDL. • Example below: The roles of ocean transport and microbial decay in determining the impacts of the Deepwater Horizon oil spill, explored with a 1/8° global ocean climate model in a collaboration between NOAA/GFDL & NOAA/OR&R. Simulated Dissolved Oil Concentrations in the Mixed Layer on July 15, 2010 Omitting Microbial Decay with Microbial Decay (6 day Half-life) Reference: A. Adcroft, R. Hallberg, J.P. Dunne, B.L. Samuels, J.A. Galt, C.H. Barker and D.Payton (2010): Simulations of underwater plumes of dissolved oil in the Gulf of Mexico, Geophys. Res. Lett., doi:10.1029/2010GL044689, in press.

  23. New Building Status • The developer stopped work in December 2008 when NCWCP construction was 80% complete. • In May 2009, the developer filed a claim in Federal Court to recover “damages” from the Government. This claim was dismissed without prejudice in August 2010. In October 2010, the developer filed an appeal; resolution of this appeal is pending. • In June 2009, the developer filed for bankruptcy with the County Court. In response, the court appointed a “Receiver” to complete the project. In November 2010, the court approved the Receiver’s plan and granted the receiver permission to resume construction. • In December 2010, the Receiver petitioned the U.S. Court of Appeals for the Federal Circuit for dismissal of the previous claim filed by Maryland Enterprises. The Federal Court granted the motion on February 9, 2011 and dismissed the claim filed by the developer. • These actions cleared away all remaining legal obstacles for the restart of work on the NCWCP project. • GSA’s goal is to reach project completion approximately 12 months after re-start of construction. GSA’s most current estimate for the building’s substantial completion is March 2012 with complete move-in by July 2012.

  24. Summary • NCEP is • Strategically aligned with NOAA’s “seamless suite” of products from the “Sun to the Sea” • Continually improving collaborative forecasts – especially for extreme events • Working with NOAA on expanded responsibilities (e.g, oceans air and water quality, ecology, space weather…); success is based on interdisciplinary approach • A critical transition agent in the NOAA “research to operations” process involving observations, data assimilation, modeling, and service delivery • Actively pursuing opportunities for collaboration in research, transition to operations and operational production and delivery of services with national and international communities 29
