  • Subject: 20041027: Decoding single sounding
  • Date: 27 Oct 2004 13:31:52 -0600
Nancy,

dcuair is used to decode the WMO format (TTAA, TTBB, PPBB, etc) sounding
data such as the bulletins in the IDD.

SNEDIT is used to import data of the format that snlist outputs. If you
put your ascii data into that SNLIST style, then snedit can be used.
The snlist output for your time is shown at the bottom of my reply.

For general reference you can download the data from FSL's web site and
decode with dcuair. Go to:
http://raob.fsl.noaa.gov/
Select the FAA604 (WMO/GTS format)
Then wrap the supplied bulletins with AFOS or WMO product delimeters
such as:

Decode the above "infile" with dcuair like:
cat infile | dcuair -c 030723/1200 -d - YYYYMMDD_upa.gem

After decoding, you should have snlist output such as:

 SNPARM = PRES;TEMP;DWPT;DRCT;SPED;HGHT

 STID = TUS           STNM =    72274   TIME = 030723/1200         
 SLAT =  32.11     SLON =  -110.93   SELV =   779.0
 STIM =  1200
