    Surface ocean velocities estimated from High Frequency (HF)-Radar are representative of the upper 2.4 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 6km resolution grid of the Puerto Rico and the Virgin Islands to produce near real-time surface current maps.

    The data set consists of maps of total velocity of the surface currents in the German Bight. Surface ocean velocities estimated by High Frequency (HF) Radar are representative of the upper 0.3-2.5 meters of the ocean.

    The data set consists of maps of total velocity of the surface current averaged over a time interval of 1 hour around the cardinal hour. Surface ocean velocities estimated by High Frequency (HF) Radar 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. Total velocities are derived using least square fit that maps radial velocities measured from individual sites onto a cartesian grid. The final product is a map of the horizontal components of the ocean currents on a regular grid in the area of overlap of two or more radar stations.

    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 between Puertos del Estado (http://www.puertos.es/) and Intecmar (www.intecmar.gal) - Xunta de Galicia.

    Coastal ocean surface current maps in different areas of the Portuguese Continental shelf measured by High-Frequency Radars (HFR) since 2016. Four HFR sites (SGTR, AFTR, VATR and MAZA-Spain) are needed for computing the map of total surface current vectors in the overlapping coverage area. HFR is routinely used for real-time monitoring of ocean currents in many places around the world with a growing range of near-real time applications (e.g. search and rescue and oil spill monitoring, navigational safety, model assessment and model improvement, throughout data assimilation).
