Hi, I've searched the archives of gembud and other Unidata lists and have
a perplexing problem. We are trying to incorporate some dropsondes into
upper air analyses here, and are having problems extracting/decoding
dropsondes using gempak's dcuair routine.
I've tried using various iterations, including a helpful message
(potentially) I found online at
http://www.unidata.ucar.edu/support/help/MailArchives/gempak/msg03215.html
that suggested manual insertion of ^A^M^M at the start of the message and
^M^M^C at the end, but I can't get the message to decode.
The command I'm executing is:
dcuair -v5 -c 20020929/0940 -b 10 -a 50 -m 50 -w 10 -d testdrop drop.snd <
drop2.txt
In this case, I have created an empty unmerged sounding file to accept
output from dcuair, since just trying to allow dcuair to create one did
not work for me. In the above example, here is the log:
[6178] 080312/1250[DC 3] Starting up. Version 5.9.3

Can anyone help sort out the problem for us here, please? Thanks. I'll
post this to support, too. Paul
