  1. National High Frequency Radar Network Jack Harlan, Ph. D. NOAA IOOS Program Office Project Manager: HF Radar DHS Training 21 Apr 2010 Washington, DC

  2. Background • Mature Technology (30+ years) for Measuring Ocean Current Velocities over Large Coastal Areas • Numerous Mission-Critical Applications • Hourly, Near-real-time • Spatial Resolution ~1 to 5 km • Relatively Low Maintenance • IOOS is Developing a Data Management and Distribution System for the Nation

  3. Outline • Network Architecture • Existing Sites and Data Products • Regional Applications • Present and Planned Activities

  4. Network Architecture • The HF-Radar Network strives to provide a scalable solution to real-time data: ● access ● distribution ● processing ● storage

  5. Network Architecture: Antelope • Antelope, an integrated collection of programs for real-time data processing, is used at the core of the HF-Radar Network. ● The real-time system is built around large, flexible, non-volatile object ring buffers (ORBs) ● Datascope, a relational database, provides a bridge between real-time processing at the ORB level and long- term storage to a local database

  6. Portals and Nodes • From a broad perspective, the HF-Radar Network is comprised of two building blocks: portals and nodes. ● Portals serve as ‘point of entry’ machines by acquiring and serving radial data from any number of HF-Radar sites ● Nodes serve as data concentrators by collecting radial data from a number of portals

  7. Portals, Nodes, Sites

  8. Portals, Nodes, Sites • Portals deployed at Rutgers, UCSB, SFSU, SLO, MBARI, SIO, OSU, USM, UMiami, UMaine • Nodes deployed at SIO, NDBC & Rutgers • Additional nodes are deployed at JPL, MBARI, USC and SLO (all part of COCMP) • 29 participating institutions, 100+ sites

  9. Radar Network Growth

  10. Real-Time Vector (RTV) ProductionWide Area Grid Development ● Grid based on equidistant cylindrical projection to preserve orthogonality throughout and provide a practical dissemination format ● Base grid extends 300km offshore with 1km nominal resolution and is landmasked ● In addition to landmasking, points falling within 0.5km of land are removed 500m, 1, 2 & 6 km resolution

  11. Real-Time Vector (RTV) ProductionWide Area Grid Coverage

  12. Google Earth Map: Existing Sites

  13. Google Earth Map: Proposed Sites

  14. Latest CODAR Technology New Compact CODAR Antenna One Pole = Receive & Transmit No Side Whips

  15. Applications • Federal, State, Local Agencies • USCG Search & Rescue • Water quality monitoring • Rip current prediction • Marine navigation • Harmful Algal Bloom Forecasts • Fisheries and ecosystem management • Oil Spill response, both NOAA and state • Hydrodynamic Modeling

  16. Example Applications/Products • Long Beach Harbor Product • NOS/CO-OPS Tidal Velocity • NOS/OR&R HAZMAT Spill Response Trajectories • SoCal Hyperion Wastewater Outfall • NoCal Ocean Beach Wastewater Outfall • S FL US Army Corps of Engineers Dredging • U Miami-NOAA Coral Larvae Drift Modeling

  17. Example Application

  18. Hyperion Outfall Diversion November 28-30, 2006 • Inspection of Hyperion Outfall Pipe (never internally inspected for 50 years). Serves City of Los Angeles. One of the world’s largest coastal populations. • Close to a billion gallons of sewage to be diverted to an in-shore/shallow outfall. • Concern of extent of impact and public health risk in the Santa Monica Bay

  19. Maritime Safety – Search And Rescue Coast Guard SAROPS MARCOOS HF Radar Network Before HF Radar After HF Radar

  20. Present and Near Future IOOS Efforts • International/national transmit licenses • January 2012 World Radiocommunications Conference • Joe Hersey: (CG-652) • Standards for Data, Files, Metadata, QC • National Plan Released Sept 2009 • Comprehensive: Gap Analysis to Detailed O&M • Available at www.ioos.gov/hfradar • National HFR data for US Coast Guard Search & Rescue with Optimal Interpolation (OI) • SBIR: Using AIS for Antenna Calibration

  21. Proposed USCG/SAR-IOOS Product

  22. Proposed USCG-IOOS Product

  23. Summary • Mature Technology (30+ years) for Measuring Ocean Current Velocities over Large Coastal Areas • Numerous Mission-Critical Applications • Hourly, Near-real-time • Spatial Resolution ~1 to 5 km • Relatively Low Maintenance • NOAA IOOS is Developing a Data Management and Distribution System for the Nation
