Sure. look at the Mathematica help (there is a less polite internet
abbreviation for this, but I have refrained from using it), such as at:
erence.wolfram.com/mathematica/ref/format/NetCDF.html
or more importantly built into Mathematica. Notice that the "export" command
can take elements, and among other things the elements can define dimensions.
