Near-Real Time Surface Ocean Velocity, Hawaiian Islands, 2km Resolution
Surface ocean velocities estimated from HF-Radar (HFR) are representative of the upper 1.0 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 2km resolution grid of the Hawaiian Islands to produce near real-time surface current maps for the most recent 90 days.
