Describe your problem or question:
Hi,

I’m attempting to run an ENSO model with CESM version 2.1.5.

I’m receiving the error "iyear0 does not match start year" and am puzzled as to where that could be coming from. My run_env file has the REF_DATE stated as "1731-03-01" and the RUN_STARTDATE as "0001-03-01". My initial run_env file was replaced with a new one so this could be where the issue lies. However, I've had previous sample runs work with the aforementioned date configuration.

Help with this would be greatly appreciated.

Thanks,

Ian

Hi, there really isn't enough information here to answer your question. It would be helpful if you tell which component is giving this error, and what your run start type is. Often errors like these occur when "CONTINUE_RUN" is true, but it should be false. Or when you are trying to start a branch run, but should be doing a hybrid start (as you can't change the start date in a branch run). What changes occurred in your run_env file? That very well may be the issue as well.
