I have timestamped wrffire and wrfchemi files but not read by real.exe (WRFV4.5)

[new_wrf1992]

I'm using WRF version 4.5 with the PREP-CHEM-SRC 1.5 utility to convert daily emission files for a two-day test case (from 2024-03-15 00:00:00 to 2024-03-16 00:00:00), with outputs every 6 hours (matching my met_em files).

I run PREP-CHEM-SRC daily and loop over each day to generate emissions. Then I use convert_emiss.exe to convert them into a single emission file (different files for different days).

• When I set chem_opt = 0, both real.exe and wrf.exe run without any issues.
• However, when I enable chem_opt and try to use the chemical emission files (wrfchemi*, wrffirechemi*), I get time mismatch errors in wrf.exe.
• Also, when chem_opt is enabled, real.exe fails and complains about missing emission files without timestamps.

• Summary:
  How to run multiple days (total simulation time):
  ------- when convert_emiss.exe does not generate timestamped outputs (without any external script),
  ------- real.exe does not read the timestamped outputs
  ------- wrf.exe says that one individual file (time stamped file created by external script) has time mismatch with the namelist. But it also reads one day file of aux_emissions.

I’m not sure how to correctly generate and link the chemical files so that both real.exe and wrf.exe can run properly. Can you help me resolve this?
