Compute mean ensemble skill for a given skill metric.

Parameters:
  • X_f (array-like) – Array of shape (l,m,n) containing the forecast fields of shape (m,n) from l ensemble members.

  • X_o (array_like) – Array of shape (m,n) containing the observed field corresponding to the forecast.

  • metric (str) – The deterministic skill metric to be used (list available in get_method()).

Returns:
