Becky,

OK, I understand.

Right.

He is getting them from the Unidata IDD.  You will recall that the origin
of the data in the IDD is a McIDAS NOAAPORT box.

>We're just trying to figure out if this is a

Hmm...  Since GEMPAK got the same grids and decoded them correctly, it
struck me that the problem must lie somewhere in the XCD decoders.  This
is why I passed the message along to you guys in the first place.

>More AVN grids are

I hope so as well.

>I've put this into inquiry #10597 and closed the inquiry as an anomoly.  If 
>we find that it is an -XCD problem, then I'll re-open the inquiry.

OK.

Have a great New Year's eve!!
