HF Radar Program

CeNCOOS maintains a network of over 20 HF Radar stations from the Big Sur Coast up to northern California and extending into San Francisco Bay.

CeNCOOS HF Radar Program Funding and History

In 2002, the Coastal Ocean Currents Monitoring Program (COCMP) began creating a California network of high-frequency radar (HFR) instruments to monitor coastal ocean surface currents in real-time and provide surface current forecasting capabilities as mandated by state funding propositions. CeNCOOS worked with COCMP to expand the HFR network in the region, and received funds for operating costs and began creating and distributing products to address stakeholder needs. California State funding for the program ended after 2010.

Current operational funding comes from solely NOAA, with a portion of our overall grant directed specifically to operating HF Radar stations. This funding covers operations and maintenance for a subset of our original HF Radar stations. These priority stations are chosen at the federal level and are selected by the economic/commercial importance of surface current measurements. leaving CeNCOOS and SCCOOS funding (estimated at 1/3 of the funds needed) to try to maintain the HFR network.

HF Radar Data Management

The HFRadar Network (HFRNet) was established to handle the data delivery of near real-time surface current data from HF Radar stations across the US. Data from the distributed national network of HF Radars is sent to the Coastal Observing Research and Development Center (CORDC), where it is then processed and served publicly in near real-time. HFRNet provides reliable data telemetry, archiving, and integrated processing for a growing list of near real-time products in a scaleable manner for a growing user community supported by the Integrated Ocean Observing System.
