20030610: Decoders dchrly and dcmetr, Ps and Ts

Tim,

It might be that dcmetr isn't finding its packing file (you
either need GEMTBL set in the environment, or have to give the path.

Try the following pqact.conf:

WMO     ^S(A....|P.....|XUS80) .... ([0-3][0-9])
        PIPE    /pub/ldm/bin2/dcmetr 
        -e GEMTBL=/YOUR_NAWIPS_PATH/gempak/tables
        -d /pub/ldm/logs/decoders.log
        -n
        gempak/surface/YYMMDD_sao.gem

With -e, the GEMTBL environmental variable is defined so that sfstns.tbl 
and metar.pack are located. If you want a more complete station table, use
-s sfmetar_sa.tbl.
If you want the data in 20 minute time bins, instead of hourly, use -m 72.
