Hi Jimmy,
First, you'll have to change your ldmd.conf file in order to get the
data. Then, if you want to do something with the data, like file it or
send it to a decoder, you'll have to modify your pqact.conf file.
We have a web page that gives many examples for pqact.conf. It's also
helpful for ldmd.conf as it gives feedtypes and patterns for many
commonly requested products. Take a look at:
http://www.unidata.ucar.edu/packages/gempak/tutorial/pqact/decoders.tbl.
In that page, if you search on AVN, you'll find this:
# AVN model output
# Grid #201 N. Hemisphere 381km: ^Y.A... KWBC.*(/mAVN|/mSSIAVN)
# Grid #202 CONUS 190km: ^Y.I... KWBC.*(/mAVN|/mSSIAVN)
# Grid #203 Alaska 190km: ^Y.J... KWBC.*(/mAVN|/mSSIAVN)
# Grid #211 CONUS 80km: ^Y.Q... KWBC.*(/mAVN|/mSSIAVN)
# Grid #213 CONUS 95km: ^Y.H... KWBC.*(/mAVN|/mSSIAVN)
# Select any/all grids desired from [QAIJH]
#HRS ^[YZ].[QAIJH]... KWB. ([0-3][0-9])([0-2][0-9]).*(/mAVN|/mSSIAVN)
# PIPE decoders/dcgrib2 -d data/gempak/logs/dcgrib.log
# -e GEMTBL=/home/gempak/NAWIPS/gempak/tables
#
# Global AVN (Spectral) Thinned grids
# Grid octets I-P will be stitched togethir as a single global grid
#
#HRS ^H.[I-P]... KWB. ([0-3][0-9])([0-2][0-9]).*
# PIPE decoders/dcgrib2 -d data/gempak/logs/dcgrib.log
# -e GEMTBL=/home/gempak/NAWIPS/gempak/tables
# data/gempak/hds/YYYYMMDDHH_thin.gem
Although these examples are for pqact.conf, you can use these as models
for what to put in both your ldmd.conf and your pqact.conf files.
Notice that you can't quite use them directly in pqact.conf - they are
commented out, and for pqact.conf you must ensure that fields are
separated by tabs, not spaces.
Hope this helps. Let me know if you have further questions.
Anne
