Global High Frequency (HF) Radar Surface Current Mapping GEO Task

1. Global High Frequency (HF) RadarSurface Current MappingGEO 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)
