[GEMPAK #JXG-744458]: Missing GEM files on new servers

Scott,

There seems to be a number of problems with your GEMPAK/LDM configuration, but 
I think I can go through everything in this message. If you need further help 
we can talk about providing me with remote access to your system and I could 
take a more direct look. More on that later.

Firstly, in January 2005, the Environmental Modeling Center at NCEP changed all 
file references for the Eta model to NAM, and GEMPAK/LDM followed suit. The 
reason your scripts are unable to open these Eta files 
($GEMDATA/model/eta/${cc}${yy}${mm}${dd}${fh}_eta212.gem) is that they simply 
do not exist, instead they've been replaced by NAM/NMM directory and file 
names. You will need to change these direct paths in your scripts, I'm sorry to 
say.

The entry for Eta/NAM in your pqact.gempak

HDS|CONDUIT|NGRID (/mETA|MT.eta|MT.nam|^[LM]..... KWBE)
PIPE decoders/dcgrib2 -d data/gempak/logs/dcgrib2_ETA.log
-e GEMTBL=/home/gempak/GEMPAK5.11.4/gempak/tables

is technically correct, since it does specify "MT.nam", but "/mETA" and 
"MT.eta" are unnecessary - it does no harm to have them included, but there 
will be no results to process. MT.nam alone will suffice.

Notice that the above pqact entry does not explicitly define an output 
directory, instead the directory is read from $GEMTBL/config/datatype.tbl.

For example, on our system here at Unidata (GEMPAK 5.11.4) there are entries in 
$GEMTBL/config/datatype.tbl for

NAM $MODEL/nam YYYYMMDDHH_nam211.gem CAT_GRD SCAT_FCT -1 -1 -1 OFF/0/0 4
ETA $MODEL/nam YYYYMMDDHH_nam211.gem CAT_GRD SCAT_FCT -1 -1 -1 OFF/0/0 4
NAM20 $MODEL/nam YYYYMMDDHH_nam215.gem CAT_GRD SCAT_FCT -1 -1 -1 OFF/0/0 4
NAM40 $MODEL/nam YYYYMMDDHH_nam212.gem CAT_GRD SCAT_FCT -1 -1 -1 OFF/0/0 4

These entries specify the directory ($MODEL/nam) and filename 
(YYYYMMDDHH_nam211.gem, for example) for the above pqact entry to send the 
output (.gem files).

If you're seeing files written to $GEMDATA/model/eta/, then you probably have a 
GEMPAK version conflict, meaning the pqact entry is reading an old version of 
datatype.tbl with $MODEL/eta specified rather than $MODEL/nam - are you certain 
you're sourcing the Gemenviron or Gemenviron.profile file correctly? Are your 
environmental variables (result of 'env') specifying 5.11.4?

Have a look at these suggestions, see if this clears up some or all of the 
problems.

If you're still having trouble, one option is to allow me to remotely access 
your system to take a quick look and fix what I can. Obviously account details 
should not be sent through email, especially to this support account. You can 
give me a call at (303)497-8674 and we can talk on the phone if you would like.

Best,

Michael
