hfradar_ushi_1km U.S. Integrated Ocean Observing System (IOOS) High Frequency Radar Network (HFRNet) Pierre Flament NOAA National Data Buoy Center (NDBC) 20120101 Surface ocean velocities estimated from HF-Radar (HFR) are representative of the upper 0.5 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. 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 1km resolution grid of the Hawaiian Islands to produce near real-time surface current maps. PacIOOS provides timely, reliable, and accurate ocean information to support a safe, clean, productive ocean and resilient coastal zone in the U.S. Pacific Islands region. 20250620T17:00:00Z 20260511T07:00:00Z Unknown -163.14439 -151.9565 24.91688 16.2204 -0.30000001192092896 -0.30000001192092896 Unknown http://pacioos.org/metadata/browse/hfradar_ushi_1km.png Sample image.
