Hi @mathause, I actually just ran into a very similar problem to your second bullet point. I had some limited success by manually re-building the re-gridded dataset onto the CESM coordinate system, swapping out the not-exactly-but-actually-close-enough coordinates for the CESM reference data's coordinates. In my case, I was re-gridding with CDO, but even when I explicitly pull out the CESM grid definition it wouldn't match precisely.

Since there was a lot of boilerplate code to do this in xarray (although I had a lot of success defining a callback to pass in with open_dataset), it was far easier just to use NCO to copy the correct coordinate variables into the re-gridded data.
