pysteps.verification.ensscores.ensemble_skill(X_f, X_o, metric, **kwargs)¶

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

out: float: The mean skill of all ensemble members that is used as defintion of ensemble skill (as in Zacharov and Rezcova 2009 with the FSS).
