|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 U.S. West Coast to produce hourly near real-time surface current maps. The subtidal current is estimated by applying a 25 hour moving average filter to the hourly surface current maps.
