forrtl: severe (66): output statement overflows record, unit -5, file Internal List-Directed Write.

Hi everyone,


I'm running into a persistent error when executing ./wrf.exe for a WRF-Chem simulation. The model crashes at the beginning of the run with the following error message:
forrtl: severe (66): output statement overflows record, unit -5, file Internal List-Directed Write.
From the log, it seems that the error occurs during the emission reading step, specifically when opening the file wrfchemi_00z_d01 at the first model time step. The message shows:
med_read_wrf_chem_emissions: error opening wrfchemi_00z_d01 followed by the Fortran runtime error.
Has anyone encountered this issue before or knows what might be causing it? Any insights or suggestions would be greatly appreciated. I've attached a zip file containing my namelist.input and rsl.error.0000 file for reference.Thank you so much in advance for your help!


Best regards

Hi,

I managed to resolve this issue. Here’s what I found and how I fixed it:

I first increased the debug level in namelist.input by setting debug_level = 300. This forced the rsl.error.* and rsl.out.* files to provide much more detailed output. After checking the detailed logs, I realized the model was crashing while trying to read the biomass burning emission files (wrffirechemi). The specific issue was a timestamp mismatch—the times defined in the wrffirechemi files did not align correctly with the simulation start/end times in my namelist.input.

So I disabled the biomass burning emission option in the &chem section of namelist.input. Once I removed those files from the workflow, the model ran successfully. Hope this helps!
 
Thank you for replying to my message. I will increase the debug level and try again. Once again, thank you.
 
The name 'wrffirechemi_d<domain>_<data>' in auxinput7_inname has some wrongly spelled letters. It really wasted a lot of my time. I hope that if anyone encounters this error again in the future, they can carefully check their spelling of the words.
