 *** ERROR ABORT in subroutine SA_IOLIST on PE 001       
 Error Opening SA_IO_LIST file

PM3EXIT: date&time specified as 0

According to the run instructions in the User Manual

The environment variable SA_IOLIST is set to the location of the ISAM control file.

SA_IOLIST 	path/filename 	Provide the location of the ISAM control file (discussed below)

In the tutorial for running CMAQ-ISAM

There are several places in your run script that would trigger this error.

  1. The environment variable CTM_ISAM is set to N, which prevents the environment variable from being set in the run script

If this is the case, then change:

setenv CTM_ISAM N

to

setenv CTM_ISAM Y

See this section of the run script.

#> Integrated Source Apportionment Method (ISAM) Options
 setenv CTM_ISAM Y
 if ( $?CTM_ISAM ) then
    if ( $CTM_ISAM == 'Y' || $CTM_ISAM == 'T' ) then
       setenv SA_IOLIST ${WORKDIR}/isam_control.txt
       setenv ISAM_BLEV_ELEV " 1 1"
       setenv AISAM_BLEV_ELEV " 1 1"
  1. there is an issue with the path for WORKDIR that is specified earlier in the script

setenv WORKDIR ${CMAQ_HOME}/CCTM/scripts #> Working Directory. Where the runscript is.

setenv SA_IOLIST ${WORKDIR}/isam_control.txt

  1. the isam_control.txt has been modified to a new name in the run script, and the corresponding file name and location does not match between what is in the run script and what is on the file system.
