zonmean: Argument 'data' not allocated!
Added by Franziska Winterstein about 5 years ago
Dear community,
I encountered an error using the zonmean operation. When applying the operation the process aborts and gives the following message:
Warning (stream_write_record): Argument 'data' not allocated!
cdo: putget.m4:805: putNCvx_double_double: Assertion `value != ((void *)0)' failed.
Abort
I am using cdo/1.9.8-magicsxx-gcc64 on the mistral postprocessing login nodes at the DKRZ. But I tried it with different versions and on a different machine with the same outcome (slightly different error message).
However, fldmean and other operations do work properly.
Do you have any suggestions?
Kind regards,
Franziska

Hi Franziska,
we need to know your data. Can you tell me where to find it on mistral.

Dear Karin,
the problem seems data independet, as I tried different files.
You find a file which did not work on: /scratch/b/b309109/R1EME-01_______205501_ECHAM5-mm.nc
Kind regards,

There is a directory called R1EME-01 and R1EME-01-re which contains different subdirectories. Can you tell me which file should be used? Are they empty?

Dear Karin,
sorry, the file was automatically deleted. It is again available under: /scratch/b/b309109/R1EME-01_______205501_ECHAM5-mm.nc (no subdirectory)
Kind regards,
Franziska

You have two horizontal and two vertical grids stored in the file. So, you have to tell cdo which one to use. You can do it with the selgrid operator or you select the variables of the same grid with selname.

Select all variables on grid 2 and compute the zonal mean:

Select the variable tsurf, which is on grid 2, and compute the zonal mean:

Dear Karin,
oh, thank you for pointing this out! It did not occured to me, that the included hybrid and scalar variables might be the problem.
Thank you very much for your help!
Kind regards,
Franziska
