copy grib2 to netcdf
Added by Jure Praznikar almost 12 years ago
When I copy grb2 file to netcdf format, I get only 21 parameters in new netcdf file.
cdo -f nc 2010091918.grb2 2010091918.nc
In new nc file is no V component of wind.
If I use command ncl_convert2nc" (NCAR Command Language Version 5.2.0), then
in nc file are all 24 parameters including V component of wind.
I assume that in original grb2 file are 24 parameters, but after using cdo there are only 21 parameters?
cdo -V

The u and v component of the wind are stored in one GRIB2 record in your file. Multiple fields in single grib records are not supported in CDO, yet. I will check whether we can implement this support in one of the next CDO releases.
Thanks for this example file!
Cheers,
