CMAQv5.5. with off-line photolysis option

CMAQ
1

I tried to conduct a test case with off-line photolysis option on the latest CMAQ v5.5. I have used ‘set ModPhot = phot/table’ and successfully compiled the CCTM. I also run JPROC to generate the JTABLE for my modeling days. However, when I submit the job, the CCTM still tries to find the inline files showing errors like ‘PHOT_OPTICS.dat not found’.

I found the manual about the photolysis at CMAQ/DOCS/Users_Guide/CMAQ_UG_ch06_model_configuration_options.md at main · USEPA/CMAQ · GitHub which explain the option 1-6 for inline, but didn’t find how to run CCTM with offline JTABLE. Is there an evnriomental variable to switch between these two photolysis options? Thanks

I still didn’t figure out the solution. Any suggestion about the off-line photolysis option? Thanks!

@haohe.umcp,

Hi can you please post your runscript and any log files you may have?

Thanks!

@fsidi Sure. Attached is my run script and log file. It stopped before creating CTM_LOG files. I aslo attached the bldit file to compile the off-line (table) CCTM.

Hi @haohe.umcp,

I suspect this is a runscript issue, not a code issue. Try commenting out the following lines in the runscript:

  if (! (-e $CSQY_DATA ) ) then
     echo " $CSQY_DATA  not found "
     exit 1
  endif
  if (! (-e $OPTICS_DATA ) ) then
     echo " $OPTICS_DATA  not found "
     exit 1
  endif

Thanks. It solved the problem!
