    • summary: Surface ocean velocities estimated from HF-Radar are\012representitive of the upper 0.3 - 2.5 meters of the\012ocean. The main objective of near-real time\012processing is to produce the best product from\012available data at the time of processing. Radial\012velocity measurements are obtained from individual\012radar sites through the HF-Radar Network and\012processed to create near-real time velocities\012(RTVs)

    • long_name: longitudinal dilution of precision
    • comment: The longitudinal dilution of precision (DOPx) represents the\012contribution of the radars' configuration geometry to\012uncertainty in the eastward velocity estimate (u). DOPx is a\012direct multiplier of the standard error in obtaining the\012standard deviation for the eastward velocity estimate from the\012least squares best fit. DOPx and DOPy are commonly used to\012obtain the geometric dilution of precision\012(GDOP = sqrt(DOPx^2 + DOPy^2)), a useful metric for filtering\012errant velocities due to poor geometry.
