Error Occurs when submitting the CESM/CLM

[liren]

Hello everyone,

I am running a single point simulation using CLM5. After producing the surface date and forcing meteorological data, I submitted the simulation. However, it stops quickly and the "cesm.log.xxx" file shows:

...

I guess this problem may raise from the discrepancy between the file description file and the input configuration file (datm.streams.txt.CLM1PT.CLM_USRDAT).

Also, my meteorological forcing data is 2 hours time steps, which is different from the GSWP3v1 or CRUNCEP. But I did not find any method to set the correct time steps. Could you please tell me how can I set the time steps.

I will attach the configuration file. The output of "ncdump -h" of input NetCDF file is also attached.

Any help would be appreciated. Thank you very much!

For troubleshooting, it's often helpful to run a case without your modifications to see how it works. This may give you insights in what you may be doing wrong.

Making changes one-by-one can also be helpful in determining the problem. For example, maybe you could make a "dummy" dataset with 2-hour time steps using copies of the GSWP3 files to see if you can get it to work.

Hi Liren, I also met this error when I ran the modified source code and input data. Have you solved this error? Looking forward to hearing from you.

Best,
Yuan

Hi, I found this error is due to variable definition. As the log shows: "NetCDF: Variable not found". So double check the code or nc file about the variable name and character numbers. refer to: pio_support::pio_die:: myrank= -1 : ERROR: nf_mod.F90: 730 : NetCDF: Variable not found

Well ... I have read your thread, and they are totally different problem.
