Near-Real Time Surface Ocean Velocity, Hawaii, 1 km Resolution

Published by Coastal Observing Research and Development Center (CORDC) | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2020-06-16T00:00:00.000+00:00
Surface ocean velocities estimated from HF-Radar (HFR) are representative of the upper 0.3 - 2.5 meters of the ocean. The main objective of near-real time processing is to produce the best product from available data at the time of processing. Radial velocity measurements are obtained from individual radar sites through the U.S. HF-Radar Network. Hourly radial data are processed by unweighted least-squares on a 1 km resolution grid of Hawaii to produce near real-time surface current maps.
