The phased array imaging radar deployed atop the CCS building was used to observe the nearshore region north of the Scripps pier. The radar measures the backscattered power and the radial component of water particle velocities. Two radars looking at the sea surface from different directions are needed to obtain water velocity vectors.
Light blue is wave crests.
The increase in crest brightness near the shoreline is associated with scattering from the breaking waves. Light blue is wave crests.
