attribute NC_GLOBAL summary String Surface ocean velocities estimated from HF-Radar are
representative of the upper 0.3 - 2.5 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 6 km resolution grid of the Alaskan
North Slope to produce near real-time surface current maps

attribute DOPx comment String The longitudinal dilution of precision (DOPx) represents the
contribution of the radars' configuration geometry to
uncertainty in the eastward velocity estimate (u). DOPx is a
direct multiplier of the standard error in obtaining the
standard deviation for the eastward velocity estimate from the
least squares best fit. DOPx and DOPy are commonly used to
obtain the geometric dilution of precision
(GDOP = sqrt(DOPx^2 + DOPy^2)), a useful metric for filtering
errant velocities due to poor geometry.
