Ocean Waves Spectral Analysis

The data/ folder contains various datasets used for analysis:

• .nc files downloaded from the CDIP website
• .csv files from THREDDS
• .npz files storing x, y, z values retrieved from THREDDS

Scripts

The scripts/ folder includes the main, completed scripts for wave spectral analysis.

xyz_spectrum.py

• Loads x, y, z data from a .npz file and generates 1D plots.
• Requires output from fetch_cdip_directional_example.py.

1d_comparison.py

• Compares custom spectral calculations against CDIP’s precomputed data.
• Evaluates the accuracy of custom methods.

spec_function_final.py

• Uses functions from utils.py to compute Fourier coefficients and energy densities.
• Generates a polar plot of energy density for comparison with CDIP’s visual output.

The example_scripts/ folder contains work-in-progress or secondary scripts.

fetch_cdip_directional_example.py

• Retrieves x, y, z variables from THREDDS and saves them in .npz or optionally .csv format.
• Intended to be used with xyz_spectrum.py.

realtime_test.py

• A simple script for testing access to the CDIP real-time dataset.
