Near Real Time Surface Ocean Total Velocity by HFR-Galicia-Total

Surface Currents

Surface ocean velocities estimated from this 5 MHz long range High Frequency (HF)-Radar are representative of the upper 2 meters of the water column. The main objective of the near-real time processing is to produce the best product from available data at the time of processing. Radial velocity measurements are obtained from the individual radar sites of the Galician HF-Radar Network. Hourly radial data are combined by unweighted least-squares on a 6km resolution regular Cartesian grid of the Galician Coast to produce near real-time hourly surface currents maps. The technical maintenance and operating is ensured by collaboration among Puertos del Estado (http://www.puertos.es/), Intecmar (www.intecmar.gal) - Xunta de Galicia and Instituto Hidrografico (http://hidrografico.pt).
