High frequency radars (HFR) from five Texas shelf stations (RLVR, SSDE, MBNP, ANWR, PINS) monitor inner-, mid-, and outer-shelf circulation. For the reanalysis of the HFR data, we applied IOOS QA/QC procedures and adopted the optimal interpolation (OI) technique to generate surface current vectors. Validation of HFR velocity vectors against Texas Automated Buoy System (TABS) currents and self-locating datum marker buoy (SLDMB)...
