[ferret_users] Up side down

[Jian Ma <jianma@xxxxxxxxxx>]

Hi All,

I was always confused with the vertical coordinate of nc files. The
attribute "down" or "up" troubles me a lot. Is there any method in
ferret to correctly plot no matter what is defined in the nc file? Or
any method to reverse it in the nc file without rewrite it using
fortran?

Thank you very much,
Tony
