Output Data Product Specifications
Surface Currents: Maps of surface current vectors created
from data taken at two radar sites spaced 80 - 150 km apart
Map Displays: color monitor screen, archived ASCII vector
files
Map Spatial Resolution (vectors on square grid): 6 x
6 km typical spacing
Map Area Coverage: Typically 100-250 km alongshore x

speed: < 7 cm/s conditions, i.e., noise/interference, siting,
sea state), direction: < 10°Data
Communication: Automatic modem transfer of current and
wave data products supported for software for dial-up lines
and ethernet connections.
