Near-Real Time Month Average Surface Ocean Velocity, U.S. West Coast, 6km Resolution

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 month average
is computed from all available hourly near real-time surface current
maps for the given month.
