High Frequency Radar Technology (HF Radar)

Ocean currents determine the movement of surface waters, providing critical information to support pollutant tracking, search and rescue operations, harmful algal bloom monitoring, vessel navigation, ecosystem-based management, and marine spatial planning.

High frequency radar technology (known as “HF radar” or simply “HFR”) is recognized as a cost-effective solution to augment the existing in-situ measurements with unprecedented spatial and temporal resolution. Through the Group on the Earth Observation (GEO), the Global HF Radar task worked to connect the many countries operating HF Radar and to support the transition of these systems to a sustained effort.
