Using CESM (cesm2_3_alpha16g) out of the box (unmodified) on derecho with a CMOM compset, if I create a run with a duration that is a fraction of a day, the time indicated by the name of the restart file for MOM6 does not match the time of the names of the other components. For example, the restart files generated for a case with STOP_OPTION=nhours, STOP_N=23 are:
c.23a16g.CMOM.T62_t061.restart.023.cpl.r.0001-01-01-82800.nc
c.23a16g.CMOM.T62_t061.restart.023.datm.r.0001-01-01-82800.nc
c.23a16g.CMOM.T62_t061.restart.023.mom6.r.0001-01-01-00000.nc
c.23a16g.CMOM.T62_t061.restart.023.dice.r.0001-01-01-82800.nc
c.23a16g.CMOM.T62_t061.restart.023.drof.r.0001-01-01-82800.nc
For a case with STOP_OPTION=nhours, STOP_N=25, the restart files that are generated are:
c.23a16g.CMOM.T62_t061.restart.025.cpl.r.0001-01-02-03600.nc
c.23a16g.CMOM.T62_t061.restart.025.datm.r.0001-01-02-03600.nc
c.23a16g.CMOM.T62_t061.restart.025.mom6.r.0001-01-02-00000.nc
c.23a16g.CMOM.T62_t061.restart.025.dice.r.0001-01-02-03600.nc
c.23a16g.CMOM.T62_t061.restart.025.drof.r.0001-01-02-03600.nc
It appears that the MOM6 component writes out a restart file for the start of the current day, rather than for the actual time of the final timestep. As a result, the short-term archiver does not move the MOM6 restart file to the restart directory in the archive location (though the other restart files do appear there).
Is there a MOM6 setting that I need to adjust to get restart files for times intervals of fractions of a day? Or is this a fixed limit?
Thanks in advance for any advice on this!
