20000202: Decoding archived data w/ DCUAIR

Patrick,

Dave blanchard must not have updated the program for 5.2.1. 
I was able to use the code from the 5.2.1 and it built with the 5.4
libraries and decoded your input data.

The tarfile is in ~gbuddy/nawips-5.4/contrib/snrawd.tar.Z

You can download this to a clean local directory and build in your 5.4
environment with:

zcat snrawd.tar.Z | tar xvf -
make

I have included your raw data in the directory as market.dat.
You should be able to decode the data by running:

% sncfil
 SNOUTF    Output sounding file              testme.gem
 SNPRMF    Sounding parameter packing file   SNMERG.PACK
 STNFIL    Station information file          snworld.tbl
 MRGDAT    Merge data file flag/part type    n
 TIMSTN    Times/additional stations         8/200
 Parameters requested: SNOUTF,SNPRMF,STNFIL,MRGDAT,TIMSTN.
 GEMPAK-SNCFIL>r

 SNCFIL PARAMETERS: 

 New sounding file:     testme.gem                                              
    
 Station file:          snworld.tbl                                             
    
 Number of stations in STNFIL:    1178
 Number of additional stations:    200
 Total number of stations:        1378
 Total number of times:              8

 This file will be an unmerged sounding file containing 
 mandatory and significant data below and above 100 mb.

Enter <cr> to accept parameters or type EXIT:
 The file has been created.
 Parameters requested: SNOUTF,SNPRMF,STNFIL,MRGDAT,TIMSTN.
 GEMPAK-SNCFIL>e


%  snrawd
 SNEFIL    Sounding edit file                market.dat
 SNFILE    Sounding data file                testme.gem
 DATTIM    Date/time                         870525/1200
 ADDSTN    Add station flag                  YES
 Parameters requested: SNEFIL,SNFILE,DATTIM,ADDSTN.
 GEMPAK-SNRAWD>r

 SNRAWD PARAMETERS: 

 Raw data file:    market.dat                                                  
 Sounding file:    testme.gem                                                  
 Time range:       870525/1200                                                  
           
 New stations will be added to the sounding file.

Enter <cr> to accept parameters or type EXIT:
 Parameters requested: SNEFIL,SNFILE,DATTIM,ADDSTN.
 GEMPAK-SNRAWD>e

% snlist
 SNFILE   = testme.gem
 AREA     = dset
 DATTIM   = 870525/1200
 SNPARM   = dset
 STNDEX   = SHOW
 LEVELS   = all
 VCOORD   = PRES
 OUTPUT   = T
 MRGDAT   = n

r


......



Everything is all set up to run in that directory with the nts files and
ancillary pdf, parm, err and hlp files. If you run elsewhere, you should 
copy those ancillary files to the appropriate directories under $GEMPAKHOME.
