GCOOS HF Radar Gap AnalysisVersion 1.0, 27 June 2008

• Consulted with– GCOOS-RA Board of Directors– Harvey Seim, SECOORA
All RA HFR Gap Analyses available at http://www.usnfra.org/committees.html
GCOOS Network of HF Radar Observing Systems for Surface Currents and Waves
• Continue operations of the existing operational High Frequency Radar
(HFR) network (6 units) in the GCOOS region;
• Determine the status of units that once were operational and whether
such units can be incorporated into the GCOOS HFR network;
• Develop a more complete understanding of quality control and quality
assurance issues for different HFR systems and how to ensure
compatibility and ability to combine measurements from different HFR
systems; and
• Develop for the Gulf a plan for choosing particular HFR station types,
operating frequencies, locations, and infrastructure plans for each site.
Gaps
• Long-Range (>75 km range) HFR: – No operational long-range HFR stations from Brownsville, TX, to Gulfport,
MS (approximately 750 mi). – USM 's long-range HFR stations cover the region from Gulfport, MS, to
Destin, FL. – Another gap exists from Destin, FL, to Redington Shores, FL (approximately
450 mi). – USF's long-range HFR stations cover the region from Redington Shores to
Naples, FL. – The region between Naples, FL, down to the Keys (~ 250 mi) and over into
the Miami, FL, area is the last GCOOS gap.
• Short- and Medium-Range HFR: There is insufficient funding to cover the entire Gulf Coast with these radars; only selected areas.
Priorities for HFR Network
• Cover the US Gulf Coast by long-distance (>75 km) radar systems with overlapping coverage sufficient to estimate 2-D surface current fields in these regions.
• Install HFR equipment that can also measure directional wave information where affordable
• Nest higher frequency radar systems within selected regions for higher spatial and temporal resolution systems is to cover regions with substantial ship and boat traffic.
– 6 NOAA Physical Oceanographic Real-Time System (PORTS)
• Houston/Galveston, TX,
• Sabine Neches, TX,
• Gulfport, MS,
• Pascagoula, MS,
• Tampa Bay, FL
– Southwest Pass of the Mississippi River
– Corpus Christi, TX
– Miami, FL
• Conduct pilot project to determine how to combine data from different HF radars into a Gulf coastal surface current map
