+Xarray checks each of these three conventions, in the order given above, when looking for dimension name metadata. Note that while Xarray can read NCZarr groups, it currently does not write NCZarr groups. After decoding the dimension information and assigning the variable dimensions, Xarray proceeds to [optionally] decode each variable using its standard CF decoding machinery used for NetCDF data.
 
 Finally, it's worth noting that Xarray writes (and attempts to read)
 "consolidated metadata" by default (the ``.zmetadata`` file), which is another
