Currents, HF Radar, Alaska - North Slope, RTV, Near-Real Time, 2010-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 Alaskan North Slope to
produce near real-time surface current maps.

由高频雷达测定的表层海流速度，可代表海洋表层2.4米深度的海流情况。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各个雷达站点获取。每小时径向数据在阿拉斯加北坡6公里分辨率的网格上进行无加权最小二乘法处理，以生成近实时表面流场图。
