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
Outline
• Network Architecture
• Existing Sites and Data Products
• Regional Applications
• Present and Planned Activities
Network Architecture
• The HF-Radar Network strives to provide a scalable solution to real-time data:
● access
● distribution
● processing
● storage
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
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
Portals, Nodes, Sites
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
Radar Network Growth
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

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
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
Example Application
• 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

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
