1. Global High Frequency (HF) Radar Surface Current Mapping GEO Task Co-Chairs Jack Harlan (USA) Lucy Wyatt (Australia) Enrique Alvarez-Fanjul (Spain)

2. GEO Work Plan 2012-2015 Endorses a task to plan a Global HF Radar Network for data sharing and delivery and to help expand HF radar networks for surface current and wave measurements. This GEO task is mentioned under – IN-01 Earth Observing Systems –SB-01 Oceans and Society: Blue Planet

3. There are 89 entities in the Group on Earth Observations 72 countries have a salty coast 35 of those countries have High Frequency radars on their coastline Approximately 410 radars worldwide

4. Type of Applications

5. Accomplishments Two International Meetings –(London 2012, Bergen 2013) Dedicated Web Page –http://www.ioos.noaa.gov/globalhfr/welcome.html Established Three Working Groups –1. Data Management –2. Applications –3. Deployment Held Two Webinars –1. Data management (April 2013) –2. Applications (June 2013)

6. Bergen 2013 Meeting ~30 Attendees from 14 nations –Australia –Canada –France –Germany –Indonesia 6 –Ireland –Korea –Malta –Morocco –Norway –Saudi Arabia –Spain –United Kingdom –USA All 3 topics discussed Additional discussion of international radio frequency management (ITU Working Party 5B, May 2013)

7. Synergies & Challenges Synergies –WRC frequency allocations –Data file formats Challenges –Data file formats –Data distribution and exchange –Data assimilation into operational models –Frequency synchronization
