I have a couple of questions about _ARRAY_DIMENSIONS. Let me make sure I understand how it is used. Suppose I am given an array X with shape(10,20,30) and an _ARRAY_DIMENSION attribute on X with the contents _ARRAY_DIMENSION=["time", "lon", "lat"] Then this is equivalent to the following partial netcdf CDL: netcdf ... { dims: time=10; lon=20; lat=30; ...} Correct? I assume that if there are conflicts where two variables end up assigning different sIzes to the same named dimension, then that generates an error. Finally it is unclear where xarray puts these dimensions. In the closest enclosIng Group? or in the root group? =DennIs Heimbigner Unidata
