20020219: CMC model data

Tim,

I have set up thelma.ucar.edu to relay the GEM model to you
at ldm.comet.ucar.edu (you are already receiving NEXRAD from thelma).
If you prefer to deal directly with CMC then they will need to know your IP
address since they had to allow the machine IPs through their firewall.
Anne-Marie will also have to add an ALLOW line to the ldmd.conf file for your
machine.

The following pqact.conf actions may be useful in filing and decoding the data:

#
# File the CMC GEM model by forecast hour
CMC     
CMC_GEM_reg_.*_.*_([12][0-9][0-9][0-9])([0-1][0-9])([0-3][0-9])([0-2][0-9])_(.*).grib
        FILE    data/cmc/\1\2\3\4_\5.cmcgem

#
# Decode the data into GEMPAK files using dcgrib2
CMC     CMC_GEM_reg.*
        PIPE    decoders/dcgrib2 -v 1 -d data/gempak/logs/dcgrib.log
        -e GEMTBL=/home/gempak/NAWIPS/gempak/tables


Let me know if you have questions regarding decoding, pqact.conf patterns etc.
