PB2NC Tool: Run

Next, run PB2NC on the command line using the following command:

bin/pb2nc \
data/sample_obs/prepbufr/ndas.t00z.prepbufr.tm12.20070401.nr.blk \
tutorial/out/pb2nc/tutorial_pb.nc \
tutorial/config/PB2NCConfig_tutorial \
-v 2

PB2NC is now filtering the observations from the Fortran-blocked input PrepBufr file using the configuration settings we specified and writing the output the NetCDF file name we chose. This should take a few minutes to run. As it runs, you should see several status messages printed to the screen to indicate progress. You may use the -v command line option to turn off or change the amount of log information printed to the screen.

Runtime Errors

Listed below are two common error message from the BUFRLIB:

• First common error message:
  +++++++++++++++++++++++WARNING+++++++++++++++++++++++++
  BUFRLIB: OPENBF - INPUT BUFR FILE IN UNIT 11 IS EMPTY
  +++++++++++++++++++++++WARNING+++++++++++++++++++++++++
  
• Second common error message:
  **************BUFR ARCHIVE LIBRARY ABORT*****************
  BUFRLIB: OPENBF - FIRST 4 BYTES READ FROM RECORD IN INPUT FILE
  CONNECTED TO UNIT 11 NOT 'BUFR', DOES NOT CONTAIN BUFR DATA
  **************BUFR ARCHIVE LIBRARY ABORT*****************

Users who encounter either of these runtime errors should consider the following:

• Ensure that BUFRLIB was built with the *same* family of compilers used to build MET.
• Go back to the PB2NC Tool: General page and follow the steps for running the cwordsh utility.
• Users running MET on a 64-bit machine should refer to the note on Running MET on 64-bit Machines.
