An inquiry about CESM2 monthly files

[hannay]

From user:

Hi Hannay,

I am a user of CESM2. I am sorry to bother you but I have an urgent question about the restart file and history file in CESM2. I am wondering if the restart file would include the accumulating history files in the middle of an accumulation period in CESM2? If it does not include, I need to stop immediately and rerun my simulations.

My experiments are very expensive so I got my restart file to be written every 10 days to avoid some abrupt stop due to memory problems or run-time limits. However, I later realized that the monthly history output may not be really monthly-mean values if my model stops before the end of one month and gets restarted from that time later. For example, if my experiment stops on Jan-20 and I restart from Jan-20, would my h0 files be the mean of whole Jan or be the mean of Jan20-Jan31 only?

Thanks a lot!

Your h0 files will be the mean of the whole January.

Note that this depends on the component. POP can also write restart history files, but it appears that CICE can not.
