CMAQ Run Time Errors and Issues

Hello, I encountered an error while running version 5.3.3 of CCTM. The error is as follows:

Is this problem due to our lack of land and lighting files? But we don’t have these two files, can we avoid using them through what settings?

If you set CTM_ABFLUX to Y (or T) to turn on the option to model bidirectional exchange of ammonia, then E2C_CHEM, E2C_SOIL, and E2C_LU are required input files You need to either set CTM_ABFLUX to N or provide the required input files from EPIC, which provide information on fertilizer application.
Further information is available in the User Guide and on the FESTC site on GitHub.

Hello, sir

When I was setting the ICON input file, for the RESTART scenario, CCTM reads files like CCTM_MEDIA_CONC_{RUNID}\_{YESTERDAY}, but these files were not generated in my OUTPUT path. I wonder if this is due to the setting of CTM_ABFLUX as N? I set it to Y, the same problem occurred as that of the previous student.

Correct. As documented in Users Guide Chapter 7, the CCTM_MEDIA_CONC restart file is only being generated when CTM_ABFLUX is set to Y:

CCTM_MEDIA_CONC: Bidirectional modeling media concentration file

This 2-D CCTM file contains the soil NH4+ and pH concentrations and/or the soil, vegetation and water Hg concentrations. This file is only created when the CTM_ABFLUX environment variable or the CTM_HGBIDI variable in the RunScript is set to Y (Default is N) for either the M3Dry or STAGE dry deposition option. For STAGE, it is used to initialize the next day of the model simulation for either the CTM_ABFLUX == Y or CTM_HGBIDI == Y case. For M3Dry, it is only used to initialize the next day of the model simulation for the CTM_HGBDIDI == Y case while the the soil NH4+ and pH concentrations written to this file for the CTM_ABFLUX == Y case are purely diagnostic. As described in Chapter 6, M3Dry relies exclusively on input files generated by EPIC to derive the soil compensation concentration for the bidirectional NH3+ flux calculation.
