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
