Sorry, @spencerkclark is right, the ValueError issue we had was also due to the 2D time bounds array only. For example: (the netCDF file used below is also at ftp://ftp.gfdl.noaa.gov/pub/s1h/atmos.201001-201012.t_surf.nc)

``` python In [1]: ds = xray.open_dataset('/archive/Spencer.Hill/am3/am3clim_hurrell/gfdl.ncrc2-intel-prod-openmp/pp/atmos/ts/monthly/1yr/atmos.201001-201012.t_surf.nc')

In [2]: print(ds)

The errors I was thinking of relating to these lat- and lon-bounds were ultimately due to errors in my own code...my mistakes appear to be the unifying theme here! Sorry for the confusion.
