I'd like to build an xarray dataset with a couple of dozen variables. All of these variables share a common first dimension, which I want to name. Some of the arrays have other dimensions, but none of those dimensions are in common with any other arrays, and I don't want to ever refer to them by name.

Currently IIUC xarray requires that all dimensions are named, which forces me to invent names for all these other dimensions. This ends up with a dataset with lots of noise dimensions in it.

I tried using None as a dimension name, but xarray treated this just as any other dimension name, and complained when the lengths were not the same in different arrays.

Is there a way to create arrays and datasets with unnamed dimensions?

Thanks in advance.
