Near-Real Time Surface Ocean Velocity, Puerto Rico and the Virgin Islands, 2km Resolution, 2025-present

Surface Currents

Surface ocean velocities estimated from High Frequency (HF)-Radar 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 Puerto Rico and the Virgin Islands to produce near real-time surface current maps.
