SCM netcdf problem

Forwarded query from Lina

I have just started using the SCM from your job xlmjb. I copied it into my xlupb and ran it on postprocessing machine following . The job seems to have run, but I got errors like "Error defining NetCDF variable: q_timen" (for all variables in file "/work/n02/n02/lboljka/SCMDATA/"). What would I have to do to get past these errors to get some output and would it come out in my work directory like it usually does or somewhere else? Do I need to specify anything in STASH and set run time>0 or not?

Eventually, I need to vary ozone and maybe surface temperature as well in it and see model behaviour. I was just wondering what is the best way to do this and to get the right outputs as well.

Awaiting jobid

Hi Grenville

This is to give you a few paths… (looking at espp1) The job in UMUI is xlupb.
The file is set up as the output file in Atmosphere→ Model resolution → Single column model - its path is


The output files might go to my usual output folder (this is something I am not sure of)


or in the umui_runs folder (name of file: "output_file_trace")


Note that I had to rerun the thing to get this output as the folder otherwise deleted itself. Also in the job itself in umui window I tried using another name for output file "" which is now the selected one in there, but before "" was used (this was just to try it out).

My bld.cfg is in


The executable (filename: "xlupb.exe") is in


I hope this helps. I am not sure at what stage a problem occurred.
Thank you.

Best wishes

I am now having problems with library:

see file

espp1$ /home/n02/n02/lboljka/umui_runs/xlupb-258180029/output_file_trace3


UM Executable : /home/n02/n02/lboljka/um/xlupb/umatmos/bin/xlupb.exe

/home/n02/n02/lboljka/um/xlupb/umatmos/bin/xlupb.exe: error while loading shared libraries: cannot open shared object file: No such file or directory
xlupb: Run failed

Do I even have all the necessary libraries connected to my account? like the netcdf one that I need for previous error and now for this one?

Thank you.

Best wishes
