Hi Tom-

You're on the right track.  At this point, the IDV can
only handle vertical coordinates of height or pressure.
(Note that "mb" is not the standard abbreviation for
millibar.  Be sure to use mbar or hPa).

What is the vertical coordinate listed as in the file?

If you need more help, let us know.  It would help to
have access to a sample file.
