[Met_help] Question on pb2nc to create daily netcdf OBS files

[Case, Jonathan (MSFC)[]]

Sorry John,

I figured out a way to process multiple PREPBUFR files using the option
you suggested.  
Here's how I got it to work:

pb2nc pbfile1 netcdf_file PB2NCConfig -pbfile pbfile2 -pbfile pbfile3
-pbfile pbfile4

For each new pbfile, I have to again specify the "-pbfile" option.  

Thanks for the help!
Jonathan
