Tools for the analysis of swells in SWOT satellite data - version 1

This software package and sample analyzed data is a first version of a suite of swell analysis from SWOT 250-m posting data (unsmoothed). The tools allow to select regions for spectral analysis, identify swell signature, remove the 180° ambiguity on the direction of propagation and subtract a noise level. More details can be found in :
