[netCDF #QAK-764753]: Variables with different dimensions

I am afraid I do not understand your explanation.
Can you give me several concrete examples of what you
want to represent?

In any case, since you are using netcdf-4, you can declare
x,y, and time to all be unlimited. Would that solve your problem?
