Greetings!I've been delving into the murky waters of BUFR for the past few months with the goal of converting our archive to netCDF. I'm working mainly (actually, exclusively up to this point) with NCEP-style BUFR files.
When I started this project, I naturally thought of netCDF java, but received errors when trying to open up the files I was wotking with, so I went with the NCEP BUFRLIB library and reacquainted myself with FORTRAN, and even learned some FORTRAN "OOP" along the way.
I'm at a point where I'm re-examining how to move forward and I've taken a look at netCDF java again and wanted to ask about the following errors when I open an NCEP BUFR file from the GTS:
manross@yslogin2[toolbox/java] % java -Xmx1024m -classpath JARS_Backup/netcdfAll-4.3.jar ucar.nc2.dataset.NetcdfDataset -in fouthsubset.bufr -out temp.nc

Obviously the error at the end is related to the inability to properly
read the file.
I am able to open the file in tools-UI and display the data, though the header column appears non-human-readable.
I know that the NCEP BUFR files come with the BUFR table embedded in them. Is this the source of the problem? If so, what is the best way around it?
