climpred.comparisons._e2c

climpred.comparisons._e2c(ds, metric=None)

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.

Parameters

• ds (xarray object) – xr.Dataset/xr.DataArray with member and ensemble dimension.

• metric (Metric) – needed for probabilistic metrics. therefore useless in e2c comparison, but expected by internal API.

Returns

forecast, reference.

Return type

xr.object
