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

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)

Radar Network Growth

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

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

Example Application

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
