Re: suggested GEMPAK 5.9.3 NAM pqact entry issue


Have you made sure that the paths listed in $GEMTBL/grid/gribkey.tbl exist? The distributed gribkey.tbl file lists a directory of "data/gempak/model/" for most products (the "data" directory should exist in /home). This was a problem I encountered once. Files were being generated, but they ended up not where I expected. The same applies to the log file directory. Also, be sure that you created a decoders directory with the "dc" programs (another mistake I once made).

I assume you've already checked for missing tabs in the pqact entries. Otherwise, you should be getting the files (I'm running version 5.9.2, but otherwise with the same entries...getting the files
written fine.

I am having problems decoding the NAM grid 212 and NAM grid 215 models using the GEMPAK 5.9.3 suggested pqact entries (the ones shipped with the distro). I also had the same problem with 5.9.1. I only want to decode the 212 and 215 gris, so I have these entries:

# NAM #212 40km grid CONUS
HDS|CONDUIT     (/mNAM|/mNMM|MT.nam|nccf/com/nam).*#212
        PIPE    decoders/dcgrib2 -d data/gempak/logs/dcgrib2_NAM212.log
                -e GEMTBL=/usr/gempak/GEMPAK5.9.3/gempak/tables
# NAM #215 20km grid CONUS
HDS|CONDUIT     (/mNAM|/mNMM|MT.nam|nccf/com/nam).*#215
        PIPE    decoders/dcgrib2 -d data/gempak/logs/dcgrib2_NAM215.log
                -e GEMTBL=/usr/gempak/GEMPAK5.9.3/gempak/tables

However, nothing gets decoded.  (I do see the files arriving).

I have to use the entry to decode all NAM models (I don't want all of them) to get 212 and 215:

#HDS|CONDUIT|NGRID      (/mNAM|MT.nam|^[LM]..... KWBE)
#       PIPE    decoders/dcgrib2 -d data/gempak/logs/dcgrib2_NAM.log
#               -e GEMTBL=/usr/gempak/GEMPAK5.9.3/gempak/tables

I am not even seeing the logfiles (dcgrib2_NAM212.log, dcgrib2_NAM215.log) being generated so maybe the pattersn for 212 and 215 aren't correct?
