Varies with environment. Comparisons with ADCPs located
in close proximity to the surface are typically < 7 cm/s of the
total current velocity and 1-2 cm/s of the tidal component.
Wavefield Products (measured at each radar): Local on-shore wave conditions
in ring centered ~3 km from coast around each radar. Significant Waveheight:
typical accuracy: 7-15%; Dominant On-Shore Direction: typical accuracy:
5 degrees -12 degrees; Dominant Wave Period: typical accuracy: 0.6 s; Other
spectral wave parameters available. Wave information is limited by environmental
conditions and operating frequency. |
