Southern California deep-water to nearshore waves lookup tables

The lookup tables relate deep-water significant wave height, peak wave period, and peak wave direction with nearshore significant wave height, peak wave period, mean wave period, peak wave direction, and directional spreading at 4,802 stations spaced ~100 m apart along the 10 m bathymetric contour and 20 intermediate-water stations coincident with CDIP buoys within the Southern California Bight from Point Conception to the Mexican border.

Deep-water significant wave height bin size = 0.25 m. Deep-water peak wave period bin size = 3 s. Deep-water peak wave direction bin size = 8 deg.

Station file = socal.loc is a text file with 4822 lat,lon coordinates for stations starting from 1 to 4822.

Lookup table files = LUT_STNtoSTN.mat Each lookup table file is a mat file containing the lookup table for 600 stations, as noted in the filename. Structures of input/deep-water significant wave height, peak wave period, and peak wave direction and output/nearshore significant wave height, peak wave period, mean wave period, peak wave direction, and directional spreading allow for easy indexing of deep-water wave conditions to find nearshore conditions at a station of interest.

These lookup tables were generated with Simulating WAves Nearshore model. Detailed modeling information can be found in:
