20000614: 20000613: decoding profiler problems

Chuck,

If you want current/realtime profiler data- then I suggest you 
use the dcncprof decoder for the hourly and 6 minute profiler data in the
FSL2 data stream.

If you have old archived data in the BUFR format that you absolutely have to 
get at, then
we can work on that- but the NetCDF data gives you both options of hourly and 6 
minute
so that would be the prefered route for the future. I haven't looked at the 
BUFR stream
in quite some time, so there may be changes between FOS and NOAAPORT.

I checked, and I see that theta.eas.slu.edu is already receiving the FSL2 feed:
Jun 14 15:22:25 notifyme[4395446]: NOTIFYME(theta.eas.slu.edu): OK
Jun 14 15:22:30 notifyme[4395446]:    11988 20000614142715.331    FSL2 000  
FSL.NetCDF.NOAAnet.windprofiler.01hr.20001661400.*
Jun 14 15:22:32 notifyme[4395446]:   177528 20000614143032.831    FSL2 000  
FSL.NetCDF.NOAAnet.windprofiler.06min.20001661412.*


So, the thing to do is make sure you have dcncprof built (it requires the 
NetCDF library
so it doesn't get built by default).

Once NetCDF is installed, edit the file $NAWIPS/config/Makeinc.common and
define the locations of the include files and library respectively line:
NETCDFINC       = /usr/local/netcdf/include
NETCDF          = /usr/local/netcdf/lib/libnetcdf.a

Then just build the dcncprof (and dcacars if you want to get the PCWS data 
stream
from FSL to look at he aircraft observations/soundings).

cd $NAWIPS/unidata/ldmbridge/dcncprof
make clean
make all
make install
make clean

cd $NAWIPS/unidata/ldmbridge/dcacars
make clean
make all
make install
make clean


LDM pattern/actions shown in the pqact.conf examples in the GEMPAK www pages 
look like:
# FSL NetCDF Wind Profiler
FSL2    ^FSL\.NetCDF\.NOAAnet\.windprofiler\.(01hr)\.(.*)\..*
        PIPE    -close  /usr/local/ldm/decoders/dcncprof -v
        -l data/gempak/logs/dcncprof.log
        -e GEMTBL=/home/gempak/NAWIPS-5.4/gempak5.4/tables
        data/gempak/profiler/YYYYMMDD_pro.gem
FSL2

        PIPE    -close  /usr/local/ldm/decoders/dcncprof -v
        -l data/gempak/logs/dcncprof.log
        -e GEMTBL=/home/gempak/NAWIPS-5.4/gempak5.4/tables

        PIPE    -close  /usr/local/ldm/decoders/dcncprof -v
        -l data/gempak/logs/dcncprof.log
        -e GEMTBL=/home/gempak/NAWIPS-5.4/gempak5.4/tables
