One way to modify small files is to use the "ncdump" and "ncgen" 
utility programs that come with the netCDF library software.

You run "ncdump file.nc > file.cdl" on your input netCDF file.nc to 
produce an equivalent text file, file.cdl.

Then you edit the text file in whatever text editor you use, to create
newfile.cdl.

Then you run "ncgen -o newfile.nc newfile.cdl" to produce the new
netCDF file corresponding to the edits you made.

Here's some slides from a netCDF workshop providing more details:

There are also other programs that can be used to edit netCDF files
through a graphical user interface, but they are not all available
for Windows, so you might have to try to build them from source:
