【CESM】B compset CAM5_PM设置

2015-09-24
LZN

Since we don’t care about the chemical process when investigate the physical climate system, we hope to close the prognostic chemistry model in CAM5. For F compset, it is easy because a specific PM compset without active chemistry model has been provided by CESM. For B compset, there is no option like this.

Therefore, we try to capture the differences in FC5PM and FC5. We first see the differences in output flow after create_newcase command.

Clearly, a PM option has been added to the CAM5 component. We try put this full name to B compset.

Things never get so smooth~

set_compset: no match for compset 2000_CAM5%PM_CLM40%SP_CICE_POP2_RTM_SGLC_SWAV
            to see supported compsets issue

It seems that we have to change it in the specific configuration file.

We then try to seek the differences in xml files. In env_build.xml,  we found an interesting differences:

40c40
< <entry id="EXEROOT" value="/HOME/sysu_hjkx_ys/WORKSPACE/L_Zealot/cesm/F/F2000_F09_CAM5_CTRL/bld" />
---
> <entry id="EXEROOT" value="/HOME/sysu_hjkx_ys/WORKSPACE/L_Zealot/cesm/F/F2000_F09_CAM5PM_CTRL/bld" />
72c72
< <entry id="CAM_CONFIG_OPTS" value="-phys cam5" />
---
> <entry id="CAM_CONFIG_OPTS" value="-phys cam5 -chem none" />

That is fine. We then add argument “-chem none” to the env_build.xml in B2000CAM5 case, setup and build, smoothly!

Now we come to the atm_in differences between FC5 and FC5PM

Such a lot differences in input files as we expected.

We test the atm_in differences between B with / without “-chem none” argument, everything goes fine!

Now we run the model for several months to test the final results.

Configuration:

B2000_CAM5

0.9x1.25

Tianhe-2: 192PEs

 

output with” phys cam5 -chem none”:

 -rw-r--r-- 1 sysu_hjkx_ys sysu_hjkx 299965072 Sep 24 15:10 B_NO_CHEM_CAM5_TEST.cam.h0.0001-01.nc

output without “phys cam5”:

-rw-r--r-- 1 sysu_hjkx_ys sysu_hjkx 305056100 Sep 24 15:23 B_CHEM_CAM5_TEST.cam.h0.0001-01.nc

So without the aerosol active, it saves (49-23)-(30-10) = 6 min in each month. About 6/26*100% = 23% time saved.
