One-Dimensional Wave Spectrum Comparison and Evaluation Dataset Based on 2022 SWIM Spectrometer Observation Data

Each CSV file contains multiple data columns, where: di_s, di_h, and di_c represent the difference index results of the one-dimensional ocean wave spectrum in three forms (slope spectrum, height spectrum, and curvature spectrum); r2_s, r2_h, and r2_c denote the goodness of fit results of the one-dimensional ocean wave spectrum in the three aforementioned forms; swh, iwage, and stp correspond to sea state parameters, namely significant wave height, inverse wave age, and wave steepness;  lat, lon, fn, and box are used to trace the sample source. lat and lon represent latitude and longitude respectively; fn is the filename of the SWIM spectrometer’s L2-level product from which the sample is derived; box is the box number of the sample source within the product filename.The Code directory attached to this dataset contains relevant code for plotting the results of the goodness of fit and difference index.The research paper associated with this dataset provides a detailed description of the formulas for the Goda spectrum, the Elfouhaily spectrum, and the Combined spectrum, and outlines the parameter fitting process for the Combined spectrum.

The parameter fitting of the Combined spectrum was performed using SWIM L2 data from 2021.To access the relevant SWIM L2 data, please visit (aviso.altimetry.fr/en/data/products/wind/wave-products/wave-wind-cfosat-products ).
