Hourly surface currents measured by high frequency Wellen radars off western Oahu, Hawaii, from September 2002 to May 2003 (NODC Accession 0013113)

A pair of High Frequency Wellen radars (WERA) shore-based at southwest Oahu (Ko'Olina) and northwest Oahu (Kaena), Hawaii measured surface currents over a nine-month period from September 2002 to May 2003. Vector currents were combined from measured radial currents on a 5-km cartesian grid by least-square fitting zonal and meridional components to radial components within a 5-km search radius. The resultant hourly data set was calibrated and quality controlled. Data provided by the originators as a MATLAB file. NODC has exported the data into ASCII files.两台岸基高频韦伦雷达（WERA）分别部署于夏威夷瓦胡岛西南部（科奥利纳）与西北部（凯阿纳），于2002年9月至2003年5月的九个月周期内开展表层海流观测。基于实测径向海流，通过在5公里搜索半径内将纬向、经向海流分量与径向分量进行最小二乘拟合，研究人员在5公里笛卡尔网格上合成了矢量海流。所生成的逐小时数据集已完成校准与质量控制。原始数据由数据创建者以MATLAB文件格式提供，美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将该数据导出为ASCII格式文件。
