  • ens (xarray.DataArray) – Ensemble forecast. The reduction dimension (ensemble members) is set by ens_dim.

  • eps ((float)) – Epsilon factor for zero values

  • clim_dim (str, optional) – Name of the climatology/quantile dimension in clim.

  • ens_dim (str, optional) – Name of the ensemble/member dimension in ens.

Returns:

EFI values.
