Clearly further subdivisions of the multi-level variables are in order. 

However, working with a single level (sea-level pressure) from our CFSR datasets, I find that if I specify the chunksize on the Time dimension when using xr.open_mfdataset, the to_zarr function fails on the resulting dataset with a ""non-uniform chunksize"" error. 

If, however, I take the resulting dataset and ""re-chunk"" with the .chunk method, although the two datasets ""look identical"", the to_zarr write succeeds.
