Currents, HF Radar, Puerto Rico and the US Virgin Islands, RTV, Near-Real Time, 2012-present, Hourly, 2km, Lon0360

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 Puerto Rico and the
Virgin Islands to produce near real-time surface current maps.

由高频雷达估计的表观海洋流速，能够表征海洋表层1.0米深度内的流速。近实时处理的主要目标是利用处理时刻可用的数据，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获取。以2公里分辨率的网格对波多黎各和维尔京群岛的每小时径向数据进行未加权最小二乘法处理，以生成近实时的表面流速图。
