Greetings!

I have been using the utility ucar.nc2.iosp.grib.Grib2Netcdf in toolsUI-4.1
successfully to convert High Resolution Rapid Refresh (HRRR) GRIB2 files to
netcdf-3.

When trying to use this utility in toolsUI-4.2, I am unable to write out
the file:

[manross@albion HRRR]$ java -Xmx512m -classpath
/mnt/home/manross/Programming/Java/toolsUI-4.2.jar

Unfortunately, I can't even find the Grib2Netcdf utility in toolsUI-4.3.

Is this utility no longer available or supported?  Is there anything like
it in 4.3?  If not, is there a chance that I could get this fixed in v4.2?

I'd be happy to supply the GRIB2 file if people want to test this.

Many thanks!!

-kevin.
