Dataset Overview | National Centers for Environmental Information (NCEI)

Near-real-time surface ocean velocities obtained by High Frequency (HF) radar in coastal waters of Gulf of Alaska, Great Lakes, Puerto Rico/Virgin Islands, eastern US/Gulf of Mexico, Hawaii, and western US during December 2023 (NCEI Accession 0287565)

Preview graphic

This dataset contains near-real-time ocean surface velocities, also known as total vector velocities, derived from HF radar stations. The velocities are arranged in a horizontal latitude/longitude grid. Measured velocities are indicative of the upper 0.3 - 2.5 meters of the ocean depending on the operating frequency and the vertical velocity profile of the water column. Data files are in netCDF format following the CF (Climate and Forecast) Metadata Conventions. Velocities are reported in CF variables surface_eastward_sea_water_velocity and surface_northward_sea_water_velocity. The National Data Buoy Center in collaboration with the Scripps Institution of Oceanography assembles the data from the Integrated Ocean Observing System Data Assembly Center's Data Stewardship Program and submits the data on a monthly basis to NCEI.

Remote sensing of ocean surface velocity from shore-based HF radar sites bridges the operational observational gap between point samples obtained from in-situ sampling and synoptic scale relatively low resolution data obtained from satellites by providing continuous mesoscale coverage at relatively high resolution near the coast.
