You cannot.
Unlike attributes, while a variable is created it cannot be
removed, just renamed (for dimensions too).
The only way to remove a variable is to make a copy of the
file without this variable.


You can do it simply (if you don't want to create a program
to do this) with the netcdf operators (NCO). For example:
ncecat -x -v VarToRemove InputFile.nc OutputFile.nc
