Data assimilation cycles
The DATA_ASSIMILATION_CYCLES
setting within CESM denotes how many model
integration, filter and inflation cycles will be attempted within a single CESM
job submission. This a typical setting for CAM:
STOP_N: 6
STOP_OPTION: nhours
DATA_ASSIMILATION_CYCLES=4
Within a single CESM ./case.submit
job, the model will run for 24 hours
with filter and inflation running at 6-hour intervals.
This is a typical setting for POP:
STOP_N: 1
STOP_OPTION: ndays
DATA_ASSIMILATION_CYCLES=5
So within a single CESM ./case.submit
job, the model will run for 5 days
with filter and inflation running daily.
Note
The CESM RESUBMIT
setting is distinct from DATA_ASSIMILATION_CYCLES
.
The value that RESUBMIT
is set to denotes how many times
./case.submit
will be invoked. Each submitted job must be completed
within the period denoted by JOB_WALLCLOCK_TIME
.
