climpred.comparisons._e2c(initialized: Dataset, metric: Metric | None = None, verif: Dataset | None = None) → Tuple[Dataset, Dataset][source]#

Compare ensemble mean forecast to single member verification.

If the initialized dataset is concatinated in a way that the first member is taken from the control simulation, this compares the member mean of all other member forecasts to the control simulation.

Comparisons for PerfectModelEnsemble

Parameters:

  • initialized – initialized with member dimension.

  • metric – needed for probabilistic metrics. Therefore useless in e2c comparison, but expected by internal API.

  • verif – not used in PerfectModelEnsemble

Returns:

forecast, verification
