Hi Andrïs,

I am happy to hear that things are working for you now!

Which decoder you want to use will depend on exactly what you want to do with
the data.  You would use the GEMPAK 'dcgrib2' if you want to use the data
in GEMPAK.

You could use the netCDF decoders package if you want to convert
the data into netCDF format.  After converting the data into netCDF you have
the option of using the netCDF utility 'ncdump' to list out the data from
the file as ASCII text.  Given this, I would recommend that you use the
netCDF decoders:

No worries.

By the way, I see that the latencies for your CONDUIT and NGRID feeds
are not very good:

    NGRID latency

The high latencies are likely a result of your feeding data over commodity 
Internet, and,
so should improve when your Internet2 connection is up and running.  Until 
then, you might
want to consider splitting your feed requests as I mentioned in a previous 
email.
