Problem Restarting WRF-Chem from 06 and 18 UTC Restart File

[Naser Mohammadzadeh]

Hello,

I am trying to restart my model at 06 UTC, but I get the following error:

1 input_wrf: wrf_get_next_time current_date: 2024-02-10_00:00:00 Status = -4 d01 2024-02-22_06:00:00 ---- ERROR: Could not find matching time in input file wrfbiochemi_d01 NOTE: 1 namelist vs input data inconsistencies found. -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 1313 NOTE: Please check and reset these options ------------------------------------------- Abort(1) on node 0 (rank 0 in comm 0): application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0

I initially thought the problem was related to my emissions, so I regenerated the EDGAR emissions with 6-hourly intervals. However, the error still occurs.

I also tried running real.exe with a start time of 06 UTC, but the same error appeared. I tested 18 UTC as well and encountered the same issue. The model only runs successfully when starting at 00 UTC and 12 UTC.

Does anyone know what might be causing this issue or how I can solve it?

Thank you for your help.

The files below are related to a simulation that was restarted from a 06 UTC restart file. I also used 12-hourly emission files for this run.

Naser,

I think it is because you are using 2 wrfchemi files, one for 00-11UTC and one for 12-23UTC. When running WRF-Chem with these two wrfchemi files, the restarts must start at either 00 or 12 UTC to allow the model to open these files.

If you must have your restart at another time, then change your wrfchemi files to individual hours and use the following in the namelist. Note that frames_per_auxinput5 is set to 1 and not 12.

 io_form_auxinput5                   = 2,
 frames_per_auxinput5                = 1,
 auxinput5_inname                    = 'wrfchemi_d<domain>_<date>',
 auxinput5_interval_m                = 60,
