Why CCTM_B3GTS_S has more than 24 hours inside

CMAQ
1

Hi,

I have been running CMAQv5.3.1 and CMAQv5.4.
In the biogenic diagnostic files from CMAQv5.3.1 I get consistent 24 hours per file. Yet in the CMAQv5.4 I am getting files that have 25 hours to 27 hours. I was wondering why this is happening in CMAQv5.4.

Thanks,
Kiarash

Hi Kiarash,

Thank you for submitting this issue. We have investigated the problem and believe we have a working fix. In tmpbeis.F, try changing the following lines:

      WSTEP   =   WSTEP + TIME2SEC( TSTEP( 2 ) )
      LASTTIC = ( WSTEP .GE. TIME2SEC( TSTEP( 1 ) ) )

      IF ( BEMIS_DIAG ) THEN
         DO K = 1, NSEF
            DO S = 1, MSPCS

to

      IF ( BEMIS_DIAG .AND. .NOT. L_DESID_DIAG ) THEN
         WSTEP   =   WSTEP + TIME2SEC( TSTEP( 2 ) )
         LASTTIC = ( WSTEP .GE. TIME2SEC( TSTEP( 1 ) ) )

         DO K = 1, NSEF
            DO S = 1, MSPCS

Warm regards,
Ben
