climpred.classes.HindcastEnsemble.verify

HindcastEnsemble.verify(name=None, reference=None, metric='pearson_r', comparison='e2o', alignment='same_verifs', dim='init')

Verifies the initialized ensemble against observations/verification data.

This will automatically verify against all shared variables between the initialized ensemble and observations/verification data.

Parameters:

• name (str) – Short name of observations/verification data to compare to. If None, compare to all observations/verification data.
• metric (str, default 'pearson_r') – Metric to apply for verification.
• comparison (str, default 'e2o') – How to compare to the observations/verification data. (‘e2o’ for ensemble mean to observations/verification data. ‘m2o’ for each individual member to observations/verification data).
• alignment (str) – which inits or verification times should be aligned? - maximize/None: maximize the degrees of freedom by slicing hind and verif to a common time frame at each lead. - same_inits: slice to a common init frame prior to computing metric. This philosophy follows the thought that each lead should be based on the same set of initializations. - same_verif: slice to a common/consistent verification time frame prior to computing metric. This philosophy follows the thought that each lead should be based on the same set of verification dates.

Returns:

Dataset of comparison results (if comparing to one observational product), or dictionary of Datasets with keys corresponding to observations/verification data short name.
