NetCDF format SWH Track data files
Where pwA is the normalised power, swh the significant wave height (m), and wt0 the fitted waveform bin position retrieved using the semi-analytical retracer. PPeakiness the pulse peakiness, lat the latitude, lon the longitude, time_av the time of the averaged 1Hz waveform. fit_error is the difference between the fitted and original 1Hz waveform.
