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

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.

由高频雷达测定的表层海流速度，能够表征海洋表层2.4米深度范围内的流速。近实时处理的主要目标是从处理时的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。每小时径向数据在美国西海岸6公里分辨率的网格上通过未加权最小二乘法进行处理，以生成近实时的表层海流图。
