Currents, HF Radar, US West Coast, RTV, Near-Real Time, 2012-present, Hourly, 2km

Surface ocean velocities estimated from HF-Radar are representative
of the upper 1.0 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 2km resolution grid of the U.S. West Coast to
produce near real-time surface current maps.

由高频雷达估计的表观海洋流速，表征了海洋表层1.0米内的流速。近实时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单个雷达站点获取。以2公里分辨率的网格对美西海岸的小时径向数据进行无加权最小二乘法处理，以生成近实时的表面流速图。
