Abstract:

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 6 km resolution grid of Hawaii to produce near real-time surface current maps.

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.
