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 2012. Two HFR sites (EPSM and JLSM) 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).

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 Hawaiian Islands to produce near real-time surface current maps.

Global Ocean - Gridded In Situ reprocessed carbon observations - SOCATv2019. Surface Ocean Carbon Atlas (SOCAT) Gridded (binned) SOCAT observations, with a spatial grid of 1x1 degree and yearly in time. The gridded fields are computed from the monthly 1-degree gridded data, which uses only SOCAT datasets with Quality Control (QC) flags of A through D and SOCAT data points flagged with World Ocean Circulation Experiment (WOCE) flag values of 2. This yearly data is computed using data from the start to the end of each year as described in the summary attribute of each variable.
