What makes you think the program is not working?

You can read short data (2-byte) as integer data (4-byte), and you
will double the size of your data, but that's OK. Is this what you are
seeing?

If you do an ncdump on the file, do you see the data you expect?

Have you used ncgen to create a fortran program to read this file? Try
that, and compare it to your program.

If none of this helps, you need to send some more information.

Good luck!
