Hi @oleson,
I need your help. I carefully read userguide about spinup and I also look through the related content in CESM forum. But I am still confused about some details.
My research topic is about agricultural management. I want to use FHIST_BGC and I modify surface data and source code. My analysis period is 2010-2020. I wonder whether my spinup design as shown below is right.
First spinup:
I2000Clm50BgcCrop;
CLM_ACCELERATED_SPINUP=on;
RUN_TYPE=startup;
leave RUN_STARTDATE, GET_REFCASE, and RUN_REF* as default
STOP_OPTION=nyears
STOP_N=1000
vi my_cesm_sandbox/components/clm/tools/contrib/SpinupStability.ncl # run the script to decide whether the model is already spun up
Final spinup:
FHIST_BGC;
CLM_ACCELERATED_SPINUP=off;
RUN_TYPE=hybrid;
finidat=’the last restart file in the first spinup, i.e., *.clm2.r.*.nc’
leave RUN_STARTDATE, GET_REFCASE, and RUN_REF* as default
STOP_OPTION=nyears
STOP_N=200
vi my_cesm_sandbox/components/clm/tools/contrib/SpinupStability.ncl # run the script to decide whether the model is already spun up
Formal running (used to analyze):
FHIST_BGC;
RUN_TYPE=hybrid;
finidat=’the last restart file in the final spinup, i.e., *.clm2.r.*.nc’
leave GET_REFCASE and RUN_REF* as default
RUN_STARTDATE=2010-01-01
STOP_OPTION=nyears
STOP_N=10
The above setting is my sensitivity experiment, and it will start to run after modifying surface data and source code. To study the effects of the sensitivity experiment, I should do a control experiment that is used to compare with the sensitivity experiment. For the control experiment, if I do not modify anything, does it mean that I do not need to spinup FHIST_BGC? Is the following design right?
