Near-Real Time Surface Ocean Velocity, Hawaii, 1 km Resolution
Surface ocean velocities estimated from HF-Radar (HFR) 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. 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 1 km resolution grid of Hawaii to produce near real-time surface current maps.

Lineage Statement | 2009-07-08T00:00:00Z UH/SOEST (P. Flament) deployed HFR array at Koko Head, Oahu (KOK): 21.2608, -157.7028. 2009-12-11T00:00:00Z UH/SOEST (P. Flament) deployed HFR array at Kakaako (Waikiki), Oahu (KAK): 21.2918, -157.8631. 2010-07-28T22:00:00Z IOOS HFRNet (CORDC/UCSD) begins generating Hawaii surface currents from radial velocities. 2010-09-08T06:45:00Z UH/SOEST (P. Flament) deployed HFR array at Kalaeloa (Barbers Point), Oahu (KAL): 21.2975, -158.0836. 2013-03-26T22:30:00Z UH/SOEST (P. Flament) deployed HFR array at Kaena Point, Oahu (KNA): 21.5749, -158.2819. 2013-12-17T06:40:00Z UH/SOEST (P. Flament) deployed HFR array at Keaukaha, Hawaii Island (KKH): 19.7320, -155.0480. 2015-05-05T07:00:00Z UH/SOEST (P. Flament) deployed HFR array at Pepeekeo, Hawaii Island (PPK): 19.8472, -155.0828. 2015-09-14T19:00:00Z UH/SOEST (P. Flament) deployed HFR array at Kapolei, Oahu (KAP): 21.3114, -158.1169. 2020-06-16T00:00:00Z Exclude invalid Kaena Point, Oahu (KNA) data prior to 2019-11-30T16:00:00Z. 2021-04-19T06:19:00Z To comply with new ITU rules and frequency allocations, changed KAK range resolution from 600 m to 750 m (250 kHz to 200 kHz) and PPK from 666 m to 750 m (224 kHz to 200 kHz). Changed KAL, KOK, and KNA frequency to 16.150 MHz with 100 kHz bandwidth (1.5 km), which does not impact their range or resolution. |
