NetCDF to grib conversion: Undefined parameter table...
Added by Akio Hansen almost 10 years ago
Hi everyone,
at first thank you all for the very powerful and amazing cdo's! Yes, they really simplify our day to day work a lot!!!
I'm actually trying to convert the DWD RADOLAN composite radar reflectivity files from a binary format to a standarised grib file to work with the files in some program, which only supports GRIB1. So far, I've sucessfully converted the binary file to a NetCDF file and now try it to convert it to grib, which is also working more or less. But my problem is, if I look at the grib output file with e.g. wgrib or IDV I get always the following error message:
"wgrib -s raa00-pc_10015-1508101500-dwd---bin.grb
Undefined parameter table (center 0-0 table 212), using NCEP-opn
1:0:d=70010100:MSLMA:sfc:anl:NAve=0"
If everything would be fine, the variable should be 129.212, so the "Maximum/Composite Radar Reflectivity [dbZ]", as it is written in the GRIB table: http://grepcode.com/file/repo1.maven.org/maven2/edu.ucar/grib/4.5.5/resources/grib1/ncep/ncepGrib1-129.xml?av=f
I convert the netcdf file with the following command: "cdo -f grb -setparam,129.212 nc_file grb_file".
Therefore my question is, how could I set the parameter table for the conversion? I've also tested the cdo option "-setpartab", but this is only locally, or isn't it? Or what options do I also have to set?
Thank you very much for all your help!
Best regards from Hamburg,
Akio
PS. I've attached you the NetCDF file, which I will try to convert.

Hey together,
after another day of googeling and reading through the very valuable forum here, I found a solution using the "grib_set" command. Thus my script is now as follows:
@# Call cdo's for file conversion
cdo -f grb -setparam,129.212 nc_file grb_file_1
- Set correct GRIB parameters for GRIB table
grib_set -s table2Version=129 grb_file_1 grb_file_2
grib_set -s centre=7 grb_file_2 grb_file_3
grib_set -s indicatorOfParameter=212 grb_file_3 grb_file@
Thanks a lot for the impressive cdo tools!
