MPAS crashes with EXIT CODE: 174

[Hung Nguyen]

Dear all,

I am running MPAS (compiled with SMIOL I/O library) with ERA5 data. I could use init_atmosphere_model to generate the init and lbc files but when I ran atmosphere_model, the model crashed instantly with exit code 174 (Please see the out_run.txt file). I am new to MPAS and do not know how to solve the problem. Below are the libraries and the compilers I used to compile the model:

netcdf 4.8.1.1
hdf5 1.12.1.1
ifort (IFORT) 2021.5.0 20211109
mpich-3.0.4

I also attached my atmosphere.namelist and the log.atmosphere.0000.out for your reference. Please help me solve the problem. If you need any additional information please kindly let me know.

Thank you

Regards,

In the out-run.txt file there are some messages like

Flerchinger USEd in NEW version. Iterations= 10

I think these errors (which unfortunately do not mention the word "error") often result from problems with soil fields. Could you check the soil temperatures in your initial conditions file to verify that they are reasonable for all non-water cells?

Dear mgduda,

Thank you very much for your reply. I have plotted a map of soil temperature from my initial conditions file and I notice something strange with the soil temperature over a part of China. I am not sure if it is the cause of the crash or not. I would like to ask if the soil temperatures cause the crash, how do I solve the problem?

Regards,

If the negative soil temperatures are only a result of the way that the soil temperature field was processed, then some adjustments to the processing workflow might help. On the other hand, if the soil temperatures in the original ERA5 files contain negative values (and assuming these should be in kelvins), then switching to a different dataset for soil fields might help.

From where have you obtained the ERA5 reanalyses, and in what format are they provided? What steps were used to convert to the "intermediate" format? Can you try making a plot of the soil temperature field from the original ERA5 files that you've downloaded?
