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

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. Nodes deployed at SIO, NDBC & Rutgers
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
The nodes at JPL, MBARI, USC and SLO are funded as part of the State of California’s Coastal Ocean Current Monitoring Program (COCMP)

9. Radar Network Growth

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

11. Real-Time Vector (RTV) Production Wide Area Grid Coverage
Adding Puerto Rico, N Slope of Alaska and Hawaii
