20051104: 20051104: sncross



Jimmy,

The hundredths units on pressure shouldn't cause a problem.
Your soundings should be ordered bottom to top (the only
problem going the other way is that filter for the winds won't work).
Presumably, there aren't any negative or 0 pressure levels.
Are they monotonic in your file?

I'd be happy to take a look if you want to post one of your files.
