Issue with making Ocean File time-dependent for CMAQ v5.4 (CB6r5m_ae7_aq) simulation

Hi everyone,

I was trying to make a time-dependent Ocean file which included time-dependent variables like OPEN, SURF, CHLO, DMS and their related TFLAG, in order to use daily-resolution DMS grid data to replace the monthly averaged version. However, when I tried to use this time-dependent oceanfile in my CMAQ simulation, it appeared that I encountered the error message “*** ERROR ABORT in subroutine retrieve_ocean_d on PE 026 Could not read OPEN from OCEAN_1" in the log. In this OCEAN FILE, the SDATE was ‘2017198‘; 25 days DMS data were incorporated; for OPEN and SURF, I just copied the first day result 25 times. Detailed information about my Ocean File are listed as follows.

I also noticed a similar issue solved by @barronh . Could you give me some suggestions to run simulation with a time-dependent Ocean file?

Thanks for your reply in advance!
