climpred.comparisons._m2c(ds, metric=None)[source]

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

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

  • metric (Metric) – if deterministic, forecast and reference both have member dim if probabilistic, only forecast has member dim

Returns

forecast, reference.

Return type

xr.object
