Currents, HF Radar, US West Coast, RTV, Near-Real Time, 2012-present, Hourly, 500m, Lon0360

Surface ocean velocities estimated from HF-Radar are representative
of the upper 0.3 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 500m resolution grid of the U.S. West Coast to
produce near real-time surface current maps.

利用高频雷达技术估计的表层海洋流速，准确反映了海洋表层0.3米深度的流速状况。近实时处理的主要目标是在数据处理时，从现有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。美国西海岸500米分辨率的网格上，通过无加权最小二乘法对小时径向数据进行处理，以生成近实时的表层流场图。
