19990713: ACARS programs



Steve,

Ok...I repacked the tar file:
http://www.unidata.ucar.edu/packages/gempak/contrib/acars_990810.tar.Z

This is the pqact.conf action I am currently using:
PCWS    ^FSL\.NetCDF\.ACARS\.QC
        PIPE    -close  /usr/local/ldm/decoders/dcacars -v -b 30
        -e GEMTBL=/home/gempak/NAWIPS-5.4/gempak5.4/tables
        -l data/gempak/logs/dcacars.log
        data/gempak/acars/YYYYMMDDHHNN_acars.gem


The "-b 30" flag tells the decoder to bin the observations into 30 minute
files when the NN template is detected. So, I get 1 file for each 30
minute time period. The data within the file remains at 1 minute
observations. The -b time period is configurable....but probably not
necessary or useful to create files containing less than 30 minutes of
observations ince it would result in very few observations for
the composite sounding.
