Robert,

The raw upperair reports aren't available in snlist. The only way to
output the PPDD portion would be to look at the unmerged decoded portion.

However, it is very simple to extract the ascii lines you want from 
the raw files you are storing using awk.

Below is a quick example of a csh script that uses awk to pull out the
lines of a report which matches a station desired through the line
containing an "=" character. You can modify the script as necessary for
a cgi by setting the ASTN and PART portion from your HTML and
the FILE names you wish to search through using any criteria needed.

<<<<<<<< sample csh script called upair.awk >>>>>>>>>
#!/bin/csh -f

set ASTN=72469
set PART=PPDD
set FILE=/shemp/data/ldm/upperair/1999070712_upa.wmo

awk -v ASTN=${ASTN} -v PART=${PART} \
   'index($0,ASTN) != 0 && index($0,PART) != 0 { print \
   while(index($0,"=") == 0) \
      { getline; print $0 } \
   printf "\n" \
   }' $FILE


Sample output: 

[343]chiz on flip --> upair.awk
PPDD 72469 NIL=
