This process can be adapted for other BUFR data as well. For instance, from Brazil we received two different BUFR files

SYNOP-wsi.bfr

climat-wsi-test.bfr

To find the proper encoding function to replace bufr_encode_new in the script, we can use the ecCodes command line tool bufr_dump

bufr_dump -E python SYNOP-wsi.bfr > SYNOP-wsi.bfr.py

bufr_dump -E python climat-wsi-test.bfr >climat-wsi-test.bfr.py

This command generates a python script that contains the code to update the bufr_encode_new function.

    # Create the structure of the data section
    codes_set_array(ibufr, 'unexpandedDescriptors', ivalues)

As the bufr_encode_new function receives a handle ( ibufr) from the message_encoding function so the first line

ibufr = codes_bufr_new_from_samples('BUFR4')

is not needed as the message handle is provided by the message_encoding function.

The tool bufr_dump can generate code in Fortran90, Python, C and ecCodes filter language ( that can be executed and tested with bufr_filter command line tool). More information, examples etc available at

UPDATES

Updated the code to encode BUFR and fixed dataframes. Includes new command line options to provide the Wigos Identifier tables and log file, Jose Mauro Resende provided the Wigos Identifier csv file and contributed to the code.

This is a test program to encode Wigos Synop 
requires 

1) ecCodes version 2.8 or above (available at https://confluence.ecmwf.int/display/ECC/Releases)
2) python2.7

To run the program

   ./test_wigos_NEW.py -a Ascii_csv_file  -b output_Bufr -w WIGOS_TABLE_FILE -l logFile
   
Uses BUFR version 4 template  301150 307091

Author : Roberto Ribas Garcia ECMWF 27 Sep 2018
Modifications
Author : Roberto Ribas Garcia ECMWF 7 Nov 2018
         added new command line option to read the station codes
         changed logic to read station codes and update bufr accordingly
         added logging information 
         Roberto Ribas Garcia, ECMWF 24 Jan 2019 changed the encoding function
         to have one header.

Changed the bufr structure at request from Brazil. Now, there is only one bufr header and the different stations appear as subsets of the message.

The new program is not complete. Some work is requiered on the user side to fully adapt to the bufr structure and perhaps simplify the bufr_encode_new function.
