CMAQ emission file question

CMAQ Run Time Errors and Issues
,
1

Hello all,

I’m currently working with CMAQ_v5.3.3 and encountering an error related to my emis file. Interestingly, I have previously run the model successfully using the same file. After modifying the emission source file to include multiple vertical layers instead of just one (which is my final goal), I still encountered this error.

     >>--->> WARNING in subroutine RDTFLAG
     Time step not available in file GR_EMIS_001      for variable AACD
     M3WARN:  DTBUF 0:00:00   May 21, 2013  (2013141:000000)
     
     >>--->> WARNING in subroutine XTRACT3
     Time step not available for file:  GR_EMIS_001
     M3WARN:  DTBUF 0:00:00   May 21, 2013  (2013141:000000)


     *** ERROR ABORT in subroutine retrieve_time_de on PE 000
     Could not extract GR_EMIS_001      file
 PM3EXIT:  DTBUF 0:00:00   May 21, 2013  
     Date and time 0:00:00   May 21, 2013   (2013141:000000)

The error message suggests that there is an issue with the time step in my emis file. However, upon investigation, I couldn’t find any errors myself.

I have searched for similar questions online but haven’t come across a solution that addresses my problem.

I have attached the complete CTM_LOG file and the ncdump containing information about the emission file.
CTM_LOG_000.v533_intel_EA36EA_20130521.txt (11.6 KB)
ncdump4emisfile.txt (16.0 KB)

Greatly appreciate any assistance you can provide!

Best regards

Quick check: what does M3Tools program m3stat say about this date&time for this variable AACD in this file?

Thank you for the reminder! It is indeed due to an issue with the TSTEP in my emission source file. Specifically, the year was missing. After making adjustments, it can now run smoothly.
