Currents, HF Radar, US East Coast and Gulf of Mexico, 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 U.S. East and Gulf
Coast to produce near real-time surface current maps.

由高频率雷达估算的海面流速，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利用处理时的可用数据生成最佳产品。径向速度测量数据通过美国高频率雷达网络从各个雷达站点获取。每小时径向数据在美国东海岸和墨西哥湾沿岸2公里分辨率的网格上，通过未加权最小二乘法进行处理，以生成近实时的海面流场图。
