[IDD #LFO-343862]: No GFS 0.5degree since yesterday

Hi Gyorgi,

> Do I need to change anything in my setup?

Most likely yes.  NOAA/NCEP switched generation of products that get distributed
in CONDUIT to a new super computer, and part of the upgrade was a slight change
in the Product IDs for GFS model output.

Very simply, the change that was made (again, by NCEP, not us) can be seen in 
two
'notifyme' snippets:

pre-update of NCEP super computer:

data/nccf/com/gfs/prod/gfs.20220629/12/atmos/gfs.t12z.pgrb2.1p00.f003 
!grib2/ncep/GFS/#000/202206291200F003/RELH/500 hPa PRES! 000350
20220629T153848.938716Z

after update of NCEP super computer:

data/nccf/com/gfs/v16.2/gfs.20220629/12/atmos/gfs.t12z.pgrb2.1p00.f003 
!grib2/ncep/GFS/#000/202206291200F003/RELH/500 hPa PRES! 000350
20220629T153848.938716Z 

The change was 'prod' field is now 'v16.2'.

Give the above, your LDM pattern-action file action(s) that are used for 
processing CONDUIT
products will need to be modified to replace 'prod' in the extended regular 
expression
(ERE) with '.*'.  Here is an example of the kind of change we need to make for 
TDS GFS processing:

old action:

#
# GFS Global 0.25 degree analysis only
#
CONDUIT ^data/nccf/com/gfs/prod/gfs\.(........)/(..).*pgrb2\.0p25\.a
        FILE
        
/data/ldm/pub/native/grid/NCEP/GFS/Global_0p25deg_ana/GFS_Global_0p25deg_ana_\1_\200.grib2


modified action:

#
# GFS Global 0.25 degree analysis only
#
CONDUIT ^data/nccf/com/gfs/.*/gfs\.(........)/(..).*pgrb2\.0p25\.a
        FILE
        
/data/ldm/pub/native/grid/NCEP/GFS/Global_0p25deg_ana/GFS_Global_0p25deg_ana_\1_\200.grib2

Note that the 'prod' field was simply replaced by '.*' (no quotes, of course).

NB:

After making a change to a pattern-action file that is in active use, you do 
_not_
need to restart your LDM for the change(s) to take effect.  All you have to do
is:

-- edit the action(s) in the pattern action file(s)

-- check that there were no gross typos in the edit:

ldmadmin pqactcheck

-- if there were no errors indicated, send a HUP signal to the lead LDM server:

ldmadmin pqactHUP

re:
> I have ldm 6.13.16, and the new community gempak 15.0.

The version of the LDM will not matter, and I can't imagine that
the version of GEMPAK will matter either.

Please let us know if you have questions on the above.

Cheers,

Tom
