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 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

10. Real-Time Vector (RTV) Production Wide 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
