Processing GRIB files with CDO for WRF input
Added by Steffen Stökler over 11 years ago
Hello everybody,
i experience some trouble when I try to use input GRIB1 files for WRF (ungrib.exe) after I merged them with CDO.
What I tried to do is simple:
I receive three separate ERA-interim datasets in grib format from ECMWF (1 that contains surface data, 1 contains data with pressure levels and 1 with static data).
All datasets are in the same gaussian N128 grid and cover the same region/timespan.
All I did is merge them to one big dataset that contains all parameters in a first step (using "cdo merge")and split them with "cdo -splitsel,1 infile.nc outfiles*" into many separate 6-hour datasets in a second step.
Now my question: Is it possible that some of the header information gets lost when merging the data? What would be an appropriate method to prepare grib data with cdo for WRF?
I hope somebody can help me! Thank you!
Best regards,
Steffen

Hello again,
in the meantime I solved the problem. It wasnt a CDO issue. I tried to merge the wrong data but now everything works fine with CDO!
Best regards
