wavespectra.core.select.sel_idw(dset, lons, lats, tolerance=2.0, max_sites=4, sitename='site', lonname='lon', latname='lat')[source]#

Select sites from inverse distance weighting.

Parameters:
  • dset (Dataset) – Stations SpecDataset to interpolate from.

  • lons (array) – Longitude of sites to interpolate spectra at.

  • lats (array) – Latitude of sites to interpolate spectra at.

  • tolerance (float) – Maximum distance to use site for interpolation.

  • max_sites (int) – Maximum number of neighbour sites to use for interpolation.

  • sitename (str) – Name of site dimension.

  • lonname (str) – Name of longitude coordinate.

  • latname (str) – Name of latitude coordinate.

Returns:

Selected SpecDataset at locations defined by (lons, lats).

Note

Args dset_lons, dset_lats are not required but can improve performance when

dset is chunked with site=1 (expensive to access station coordinates) and improve precision if projected coordinates are provided at high latitudes.
