argopy.utils.fill_variables_not_in_all_datasets#

fill_variables_not_in_all_datasets(ds_collection: List[Dataset], concat_dim: str = 'rows') → List[Dataset][source]#

Add empty variables to dataset so that all the collection have the same xarray.Dataset.data_vars and :props:`xarray.Dataset.coords`

This is to make sure that the collection of dataset can be concatenated

Parameters:

  • ds_collection (List[xarray.Dataset]) – A list of xarray.Dataset

  • concat_dim (str, default='rows') – Name of the dimension to use to create new variables. Typically, this is the name of the dimension the collection will be concatenated along afterward.

Return type:

List[xarray.Dataset]
