summary:
Surface ocean velocities estimated from HF-Radar are representitive 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 HF-Radar Network and processed to create near-real time velocities (RTVs)

longitudinal dilution of precision
(Type is String)
comment:
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.
