I'm embarrassed I even posted this! It looks like the nbnds and time_bnds variables were added to the yearly files at some point. Accordingly, a simple conditional checking for their existence and subsequently deleting them prior to concatenation did the trick. Too bad there is absolutely no consistency in these files at all.

Xarray doesn't know what to do in this situation, so it raises an error. You'll need to add some custom processing logic to make the datasets consistent before you merge them. In principle, we could handle missing variables by adding NaNs, possibly by adding a flag `allow_missing_variables` to `concat`. But this doesn't exist yet.
