OK.

To be precise, the products received by the LDM would have to be written
into a gdbm database in a particular manner to be used by Peter's 'weather'
application. Your FILE actions will simply write the products to disk
if/when they are received.

The easiest AND quickest way to figure this out yourself is by using
the LDM 'notifyme' utility. For instance, here is the notifyme invocation
that will check for the availability of the FOUS12 products in the queue
of the top level IDD relay, idd.unidata.ucar.edu:
notifyme -vxl- -f ANY -o 10000 -h idd.unidata.ucar.edu -p '^FOUS12 ....
([0-3][0-9])([0-2][0-9])'
Notes:
- '-o 10000' says to look back 10000 seconds from the present in the LDM
queue on the host idd.unidata.ucar.edu ('-h idd.unidata.ucar.edu')
- -p '^FOUS12 .... ([0-3][0-9])([0-2][0-9])' specifies the pattern to search
for in product's WMO header (note the single quotes around the pattern!)
This 'notifyme' invocation returned the following when I ran it a minute ago:
Mar 01 05:04:12 notifyme[16677] NOTE: Starting Up: idd.unidata.ucar.edu:

Mar 01 05:04:27 notifyme[16677] NOTE: exiting
Note:
- the last line that says 'exiting' was written because I killed the invocation
with CRTL-C
- the datastream containing the FOUS12 product is actually IDS|DDPLUS
For reference, WMO is a compound feedtype:
WMO == IDS|DDPLUS|HDS
A similar 'notifyme' invocation whose pattern expression ('-p') was the one you
had for
FOUS20 products listed nothing. This implies that the products with an ID that
would
match the pattern are no longer in the datastream, or none of those products
have been
received in the 10000 seconds previous to when I ran 'notifyme'.
The 'notifyme' utility is _extremely_ useful in:
- checking for the availability of products in the IDD
- testing patterns for use in pqact.conf actions
- searching through your own LDM queue to see if you have received
a particular product. To search your own LDM queue, simply leave
out the '-h hostname' specification.
Next:
A Google (tm) search using 'mos wmo header' as a search key yields a number of
useful documents describing MOS products. For instance:
http://www.weather.gov/mdl/synop/stadrg.php
contains information on 'Current GFS and Eta MOS Stations and WMO Headers'.
To test if any of the headers listed in the www.weather.gov page are available
in the
IDD (if the products are broadcast in NOAAPort, they will be in the IDD), use
'notifyme'
in a manner similar to the example above.
For instance, look up the MOS header for New Jersey stations in the
www.weather.gov
web page and you will find:
Northeast U.S. Region MOS text product WMO headers/AWIPS ids:
FOUS21 KWNO / MAVNE1 - GFS short-range MOS for Northeast U.S. {233}
FEUS21 KWNO / MEXNE1 - GFS Extended-range MOS for Northeast U.S. {233}
FOUS44 KWNO / METNE1 - Eta MOS for the Northeast U.S. {233}
So, try a notifyme using '-p FOUS21 KWNO' for GFS short-range MOS,
'-p FEUS21 KWNO' for GFS Extended-range MOS, and '-p FOUS44 KWNO' for
Eta MOS, all for the Northeast U.S.
One example of this is:
notifyme -vxl- -f ANY -o 10000 -h idd.unidata.ucar.edu -p 'FOUS21 KWNO'
etc.
> If not, is there another way to pull MOS text out of the LDM?
Please see my comments above and let me know if you have any questions.
> I spent quite a while searching the unidata support site
> but couldn't find much in the way of help for this one..
The MOS products are broadcast by the NWS, so they are the best source
for information on the WMO headers for the products.
> Thanks!
No worries.
Cheers,
Tom
