wavespectra.SpecArray.interp

SpecArray.interp(freq=None, dir=None, maintain_m0=True)

Interpolate onto new spectral basis.

Parameters:

• freq (-) – Frequencies of interpolated spectra (Hz).

• dir (-) – Directions of interpolated spectra (deg).

• maintain_m0 (-) – Ensure variance is conserved in interpolated spectra.

Returns:

Regridded spectra, returned as a Dataset with

the non-spectral variables preserved when called from the Dataset accessor.

Return type:

• dsi (DataArray)

Note

• All freq below lowest freq are interpolated assuming \(E_d(f=0)=0\).

• \(Ed(f)\) is set to zero for new freq above the highest freq in dset.

• Only the ‘linear’ method is currently supported.
