Decoding the SREF using Java Grib2Netcdf

I believe this is for Robb Kambic, but if anyone else has a comment please post.

Iâm trying to decode (grib2 -> netcdf) the somewhat new SREF model data.

Hereâs the NOAAPORT entry:

HDS|CONDUIT|NGRIDÂÂÂÂÂÂ ^[LM]..... KWBL ([0-3][0-9])([0-2][0-9][0-6][0-9])

ÂÂÂÂÂÂ ÂÂÂÂ FILEÂÂÂ data/awips_in/sref/input/(\1:yyyy)(\1:mm)\1\2_sref.grib

To decode I use the following:

ÂÂÂÂÂÂÂÂÂÂÂ ï[ldm@metbox4 sref]$ java -Xmx1024m ucar.nc2.iosp.grib.Grib2Netcdf input/200707200900_sref.grib 200707200900_sref.nc

With the following output:

ÂÂÂÂÂÂÂÂÂÂÂ ïFri Jul 20 18:00:23 GMT 2007 ... Start of Grib2Netcdf

read grib file=input/200707200900_sref.grib write to netCDF file=200707200900_sref.nc

ÂÂÂÂÂÂÂ at ucar.nc2.iosp.grib.Grib2Netcdf.main(Grib2Netcdf.java:87)

I assume the error has something to do with the fact that this is ensemble mean output.Â Is there any way to get this to decode?

Thanks for any help as always!
