wavespectra.SpecArray.interp#

SpecArray.interp(freq=None, dir=None, maintain_m0=True)[source]#

Interpolate onto new spectral basis.

Args:

  • freq (DataArray, 1darray): Frequencies of interpolated spectra (Hz).

  • dir (DataArray, 1darray): Directions of interpolated spectra (deg).

  • maintain_m0 (bool): Ensure variance is conserved in interpolated spectra.

Returns:

  • dsi (DataArray): Regridded spectra.

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.
