attribute NC_GLOBAL summary String 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. West Coast to
produce near real-time surface current maps.
