Currents, HF Radar, US West Coast, RTV, Near-Real Time, 2012-present, Hourly, 6km, Lon0360

Surface ocean velocities estimated from HF-Radar are representative
of the upper 2.4 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 6km resolution grid of the U.S. West Coast to
produce near real-time surface current maps.

基于高频雷达估算的表观海面流速，能够准确反映海洋表层2.4米范围内的运动情况。实时近数据处理的主要目标是在数据处理时，从可用数据中生成最佳产品。径向速度测量数据通过美国高频雷达网络从各个雷达站点获取。通过对美国西海岸6公里分辨率的网格进行未加权最小二乘法处理，每小时径向数据被加工成近实时的海面流场图。
